AE does not only provide Job objects for operating systems but also for standard software solutions such as SAP, PeopleSoft, Oracle Applications and Siebel. These solutions to not have a JCL (Job Control Language) but interfaces.
Hence AE Script provides a range of special functions which facilitate the execution of processing statements. These functions are created with a graphical interface (FORMS) which additionally have an online connection to the particular standard system. Dropdown lists can so be used to select attributes for the functions (e.g. printer name etc).
Alternately, the statement can also be stored as usual in the Process tab of the Job object (script editor).
