MODIFY_TASK

Use the MODIFY_TASK script function to modify active STANDARD Workflows and tasks in active STANDARD Workflows. You cannot use it with IF or FOREACH Workflows. MODIFY_TASK lets you change task properties for a particular Workflow, without editing the object definitions. The task properties in the Workflow override the settings in the object definition. For more information, see Object Properties in Workflows.

Overview

Before and after making modifications with MODIFY_TASK, you must always change the Workflow status with preliminary MODIFY_TASK script lines. Follow this sequence when you modify a Workflow with MODIFY_TASK:

1. Use MODIFY_TASK with the STOP_MODIFY parameter to stop the Workflow and allow editing.
2. Use MODIFY_TASK with other parameters to make one or more modifications to the Workflow.
3. Use MODIFY_TASK with the COMMIT parameter to activate your modifications.
4. Use MODIFY_TASK with the GO parameter to start the Workflow.

Syntax and Parameters

The basic syntax of this script function contains the following elements:

MODIFY_TASK (RunID, parameters, KEYWORD)

Where:

• MODIFY_TASK
  
  Modifies an active STANDARD Workflow

• RunID
  RunID of the active STANDARD Workflow to modify

• parameters
  One or more parameters specify which task to modify, or other parameters depending on the modification

• KEYWORD
  Specifies the action to take
  All available keywords are described in this topic.
  Note: Some keywords have additional parameters after the keyword.

Important!

• You must write the parameters of MODIFY_TASK in the order in which they are shown in the syntax samples in this topic.
• You must use commas as shown in the syntax samples even if you omit individual parameters.

Several modifications that you can perform with MODIFY_TASK require you to specify a particular task. Use one or both of the following parameters to specify the task:

• task name
  Name of the task
  Note: Use START or END when you want to modify the start or end box of a Workflow.
  Format: script literal, number, or script variable.

• sequence number
  Sequence number of the task
  The sequence number refers to the number within the Workflow, such as 3 for the third task. The sequence number is displayed in the task box in the Workflow editor. The sequence number is not the RunID. For more information, see Task Boxes in Workflows.
  Format: script literal, number, or script variable.

Notes:

• If you specify both the task name and the sequence number, ensure that they match the same task.
• If there are several tasks with the same name in the Workflow and you do not specify a sequence number, the system uses the task that has the lowest number.

Sample Scenario

You want to add two tasks to a STANDARD workflow when the workflow is active. This example demonstrates how to combine MODIFY_TASK functions with several different keywords to add and place the tasks, and create the required dependencies.

Prerequisites:

• Workflow object
  For the purposes of this example, the Workflow currently has one child task.
• Two executable objects (Task.01 and Task.02)

Goals:

• Both tasks are dependent on their predecessors in the Workflow:
  • Task.01 starts when the Workflow starts.
  • Task.02 starts after Task.01 finishes.
• The Workflow ends when Task.02 finishes.

Write the following script on the Process page of the child task that is currently in the Workflow.

Syntax

:SET &RUNID# = SYS_ACT_PARENT_NR(ACT)

:PRINT &RUNID#

:SET &RET# = MODIFY_TASK(&RUNID#, STOP_MODIFY)

:SET &RET# = MODIFY_TASK(&RUNID#, 'TASK.01', ,ADD_TASK)

:SET &RET# = MODIFY_TASK(&RUNID#, 'TASK.01', ,MOVE_TASK, 2, 3)

:SET &RET# = MODIFY_TASK(&RUNID#, 'TASK.01', ,ADD_DEPENDENCY, 'START', , 'NONE' )

 

:SET &RET# = MODIFY_TASK(&RUNID#, 'TASK.02', ,ADD_TASK)

:SET &RET# = MODIFY_TASK(&RUNID#, 'TASK.02', ,MOVE_TASK, 3, 3)

:SET &RET# = MODIFY_TASK(&RUNID#, 'TASK.02', ,ADD_DEPENDENCY, 'TASK.01', , 'NONE' )

 

:SET &RET# = MODIFY_TASK(&RUNID#, 'END', ,ADD_DEPENDENCY, 'TASK.02', , 'NONE' )

:SET &RET# = MODIFY_TASK(&RUNID#, 'END', ,REMOVE_DEPENDENCY, 'START', , 'NONE' )

:SET &RET# = MODIFY_TASK(&RUNID#, COMMIT)

:SET &RET# = MODIFY_TASK(&RUNID#, GO, FORCED)

Parameters

• SYS_ACT_PARENT_NR
  Retrieves the RunID of the Workflow that the task is in

• PRINT
  Prints the retrieved RunID in the activation report

• MODIFY_TASK
  Performs a modification to the Workflow, or to a task in the Workflow

• STOP_MODIFY
  Stops the Workflow for modification purposes

• ADD_TASK
  Adds a task to the Workflow

• MOVE_TASK
  Moves the added task to the desired place (identified by the column and line) in the Workflow

• ADD_DEPENDENCY
  Draws a line to the predecessor of the added task to create a dependency

• REMOVE_DEPENDENCY
  Deletes the line to a predecessor task to remove the dependency

• COMMIT

Stopping, Committing Changes and Starting the Workflow

Use MODIFY_TASK with status parameters to stop the Workflow, make and commit your changes, and start the Workflow again. You must stop and start the Workflow to use the other MODIFY_TASK parameters described in this topic.

Syntax

MODIFY_TASK (RunID, status [, FORCED])

Parameters

• status
  Status to set for the Workflow
  Format: AE name, script literal, or script variable
  Allowed values:

  • COMMIT
    Activates modifications without starting the Workflow
  • GO
    Starts a stopped Workflow
    Use the parameter FORCED to start a workflow even if its Monitor is open for editing purposes
  • STOP
    Stops the Workflow
  • STOP_MODIFY
    Stops the Workflow for modification purposes

• FORCED
  (Optional) Starts a stopped Workflow even if the Workflow Monitor is open for editing purposes
  Use this keyword in combination with the GO Status.
  Important! Modifications made by another user will be lost if you stop the Workflow while they are editing.

Notes:

• You can only stop and start other Workflows, but not the Workflow that the script itself is in.
• You cannot use MODIFY_TASK to edit the Workflow that the script is in.

Examples

The following example stops the MM.DAY Workflow, and allows you to carry out modifications.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RET# = MODIFY_TASK(&RUNID#, STOP_MODIFY)

The following example starts the MM.DAY Workflow even if another user may be editing the Workflow.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RET# = MODIFY_TASK(&RUNID#, GO, FORCED)

Modifying Workflow Contents

The following keywords let you modify the contents of an active Workflow:

• ADD_TASK
  Adds a task in the Workflow

• REPLACE_TASK or CLONE_AND_REPLACE
  Replace a task in the Workflow

• MOVE_TASK
  Moves a task in the Workflow to a different position within the Workflow

• ACTIVE
  Activates or deactivates a Workflow task

Adding a Task or External Dependency

Use MODIFY_TASK with ADD_TASK to add a task to an active Workflow. Use the EXTERNAL keyword to add a task as an external dependency.

The task that you add is not automatically linked with other tasks. Use MODIFY_TASK with ADD_DEPENDENCY to draw the required lines. Use MODIFY_TASK with MOVE_TASK to place the task in the right place in the Workflow.

Syntax

MODIFY_TASK (RunID, object name ,, ADD_TASK [, EXTERNAL [, Workflow name]] )

Parameters

• object name
  Name of the object to insert into the Workflow
  Format: script literal, number, or script variable

• ADD_TASK
  Adds the task

• EXTERNAL
  (Optional) Adds the task as an external dependency

• Workflow name
  (Optional) Name of the Workflow to which the external dependency refers
  Format: script literal or script variable

Notes:

• Write 2 commas after the object name parameter. This third parameter is the sequence number of a task within the workflow. It is irrelevant when you add a task.
• If the Workflow is configured so that tasks inherit the AE priority of the Workflow, then the task that you add also inherits that priority.

Tip: Use the sequence number that the function returns to specify the task when making other modifications to the added task.

Example

The following example adds the object FILE.INPUT to the Workflow MM.DAY.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &RET# = MODIFY_TASK(&RUNID#,"FILE.INPUT",, ADD_TASK)
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

Replacing a Task in a Workflow

Use MODIFY_TASK with REPLACE_TASK or CLONE_AND_REPLACE to replace a particular task in the Workflow with another object. You can only replace an external dependency with an external dependency, and a regular workflow task with a regular workflow task.

Parameters

• REPLACE_TASK or CLONE_AND_REPLACE
  Replaces the task with the object that you specify

  • REPLACE_TASK 
    Sets the status of the old, replaced task to inactive

Example

The following example uses MODIFY_TASK with REPLACE_TASK to replace an external dependency (MM.GET.FILES) by an other external dependency (MM.FILE.INPUT).

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &RET# = MODIFY_TASK(&RUNID#, "MM.GET.FILES",, REPLACE_TASK, "MM.FILE.INPUT", EXTERNAL)
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

Moving a Task in a Workflow

When you use MODIFY_TASK to add a task, the added task is placed in an available empty spot in the Workflow. Use MODIFY_TASK with MOVE_TASK to move the task to the desired place in the Workflow. Specify the column and line of the desired empty place.

Syntax

MODIFY_TASK (RunID, [task name], [sequence number], MOVE_TASK , Column, Line)

Parameters

• MOVE_TASK
  Moves the task

• Column
  Number of the column to which to move the task
  Format: script literal, number, or script variable

External Dependency Tab

The following keywords let you modify settings on the External Dependencies tab of an external task in a Workflow.

• EXTERNAL_SATISFACTION
  Defines when an external task is expected to end

• EXTERNAL_STATUS
  Sets the expected status of an external task

• EXTERNAL_ELSE_ACTION
  Defines the action to take when an external task does not fulfill expectations

• EXTERNAL_TIMEOUT_ACTION
  Defines the action to take when an external task times out

More Information:

• External Dependency Tab

Defining the Execution Settings of an External Dependency

Use MODIFY_TASK with EXTERNAL_SATISFACTION to define how the Workflow handles an external dependency. The Workflow is configured to expect the external task to start or end at a particular time, such as before or after the current Workflow starts. EXTERNAL_SATISFACTION lets you modify the settings that determine the expected lead time.

Syntax

MODIFY_TASK (RunID, [task name], [sequence number],EXTERNAL_SATISFACTION , lead time satisfaction [, duration])

Parameters

• EXTERNAL_SATISFACTION
  Defines the lead time satisfaction

• lead time satisfaction
  Defines when the external dependency is considered as fulfilling expectations:

  • LOGICAL_DATE
    Checks if the external task was activated on the same logical date as the Workflow
  • LAST_EXECUTION
    Checks if the external task end is after the last Workflow execution end
  • BEFORE_START
    Checks if the external task end is within a period before the Workflow starts
  • AFTER_START
    Checks if the external task end is after the current Workflow starts

• duration
  (BEFORE_START only) Period in HH:MM:SS format
  Format: script literal or script variable

Example

In the following example, the lead time for the external dependency MM.GET.FILES commences when the Workflow starts.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &RET# = MODIFY_TASK(&RUNID#, "MM.GET.FILES",, EXTERNAL_SATISFACTION, "AFTER_START")
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

Setting the Expected Status of an External Dependency

Use MODIFY_TASK with EXTERNAL_STATUS to set the status expected for an external task.

Syntax

MODIFY_TASK (RunID, [task name], [sequence number], EXTERNAL_STATUS , status)

Parameters

• EXTERNAL_STATUS
  Sets or removes the expected status of an external task

• status
  Expected status for the external task:

  • End status
    Status such as ENDED_OK
  • NONE
    The system only checks whether the task ended within the lead time, regardless of the status

Example

In the following example, the MM.DAY Workflow expects an ENDED_OK status from the external task that is called MM.GET.FILES.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &RET# = MODIFY_TASK(&RUNID#, "MM.GET.FILES",, EXTERNAL_STATUS, "ENDED_OK")
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

Defining the Else Action of an External Dependency

Use MODIFY_TASK with EXTERNAL_ELSE_ACTION to define the action to take if an external task does not get the expected status, or does not end within the expected time.

Syntax

MODIFY_TASK (RunID, [task name], [sequence number], EXTERNAL_ELSE_ACTION , WAIT|SKIP|CANCEL [, Alarm object] )

Parameters

• EXTERNAL_ELSE_ACTION
  Determines that action is to be taken when an external task does not get the expected status at least once, or does not end within the expected time

• WAIT, SKIP, or CANCEL
  Defines the action to take:

  • WAIT
    Waits for the external task to complete
    Note: Use MODIFY_TASK with EXTERNAL_TIMEOUT_ACTION to define the timeout for this action.
  • SKIP
    Skips the external task
  • CANCEL
    Cancels the Workflow

• Alarm object
  (Optional) Name of a Notification object of Alarm type to start if a timeout occurs
  Format: script literal or script variable

Example

In the following example, the MM.DAY Workflow is canceled if the external MM.GET.FILES task does not end as expected. When the script cancels the Workflow, it starts a Notification object called DAYSHIFT.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &RET# = MODIFY_TASK(&RUNID#, "MM.GET.FILES",, EXTERNAL_ELSE_ACTION, "CANCEL", "DAYSHIFT")
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

Defining the Timeout Setting of an External Dependency

Use MODIFY_TASK with EXTERNAL_TIMEOUT_ACTION to define the timeout setting of an external task when you use WAIT and define an Else action.

Syntax

MODIFY_TASK (RunID, [task name], [sequence number], EXTERNAL_TIMEOUT_ACTION , timeout length, WAIT|SKIP|CANCEL[, Alarm object])

Parameters

• EXTERNAL_TIMEOUT_ACTION
  Determines the length of time to wait when you define an Else action with WAIT

• timeout length
  Timeout duration in HH:MM:SS format
  Format: script literal or script variable

• WAIT, SKIP, or CANCEL
  Defines the action to take:

  • WAIT
    Waits for the external task to complete
  • SKIP
    Skips the external task
  • CANCEL
    Cancels the Workflow

• Alarm object
  (Optional) Name of a Notification object of Alarm type to start if a timeout occurs
  Format: script literal or script variable

Example

In the following Workflow, there is an external dependency on a task that is called MM.GET.FILES. The Workflow skips the external task if the task fails to end as expected within 1 hour.

:SET &RUNID# = GET_UC_OBJECT_NR("MM.DAY")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &RET# = MODIFY_TASK(&RUNID#, "MM.GET.FILES",, EXTERNAL_TIMEOUT_ACTION, "01:00:00", "SKIP")
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

Modifying the Value of a Variable

Use MODIFY_TASK with VALUE to modify the value of a variable stored on the Variables & Prompts tab:

• Object variable
  Modify an existing variable value, or create a new variable with a specified value.
• PromptSet variable
  Modify an existing variable value of a PromptSet control.

• Variables Page
• Prompt Sets Page

Syntax

MODIFY_TASK (RunID, task name, sequence number, VALUE,PROMPTSET NAME|<VALUE>, VARIABLE|NEW VARIABLE, "VALUE", [SELECT|DESELECT|CLEAR|SPACE])

Parameters

• VALUE
  Modifies the value of a variable:

  • Modifies the value of an existing object variable, or creates a new object variable
  • Modifies the value of an existing PromptSet variable

• PromptSet name or <VALUE>
  Specifies the variable:

  • PromptSet name
    Name of the PromptSet object
  • <VALUE>
    Name of the object variable

• variable
  (Object variables only) Name of the new variable if the object variable does not exist yet
  Note: Write the variable name without the leading ampersand

• value
  (Optional) Value to set for the variable
  Note: You must set a value if you are modifying a PromptSet variable that is an array.
  Format: script literal or script variable

• SELECT, DESELECT, CLEAR or SPACE
  (Optional) Modifies the values selected in the variable:

  • SELECT
    (PromptSet variable arrays only) Selects rows of an array
  • DESELECT
    (PromptSet variable arrays only) Deselects rows of an array
  • CLEAR
    (PromptSet variable arrays only) Deselects all rows of an array
  • SPACE (default)
    Changes the PromptSet variable or object variable value to empty text
  Note: These keywords let you select or deselect values when the variable allows multiple values. Use these parameters to manage values from PromptSet controls such as checkboxes. The selected values can be values selected by a user, default values, or values defined for the Workflow.

Examples

In the following example, the script activates a Workflow, and stops the Workflow for modifications. The script creates a variable and assigns a value the variable.

:SET &RUNID# = ACTIVATE_UC_OBJECT("JOBP.NEW.01")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &MODIFY# = MODIFY_TASK(&RUNID#, "SCRI.NEW.01", 4, VALUE, "<VALUE>", "&&VARIABLE#", "Vienna")
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

In the following example, a Script object has an assigned PromptSet. The script modifies the values of the PromptSet variable CKG#, that is an array of values from a checklist control. The parameters in MODIFY_TASK, VALUE select the Test01 value from the PromptSet variable.

:SET &RUNID# = ACTIVATE_UC_OBJECT("JOBP.NEW.01")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &MODIFY# = MODIFY_TASK(&RUNID#, "SCRI.NEW.01", 4, VALUE, "PRPT.NEW.01", "CKG#", "Test01", SELECT)
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)

In the following example, the value of the PromptSet variable Textfield01# is set to mytextfieldvalue.

:SET &RUNID# = ACTIVATE_UC_OBJECT("JOBP.NEW.01")
:SET &RETSTOP# = MODIFY_TASK(&RUNID#, STOP_MODIFY)
:SET &MODIFY# = MODIFY_TASK(&RUNID#, "SCRI.NEW.01", 4, VALUE, "PRPT.NEW.01", "Textfield01#", "mytexfieldvalue")
:SET &RETCOMMIT# = MODIFY_TASK(&RUNID#, COMMIT)
:SET &RETGO# = MODIFY_TASK(&RUNID#, GO)
