Best Practices: Assigning the Right Priority
When jobs are waiting for a free batch process in SAP to be executed, their priorities determine which jobs go first.
When defining an SAP ABAP job in the Automation Engine, you also assign it a priority in the SAP system. You do this in the Job Class dropdown list on the SAP page of the Job object definition. The available options are A (highest priority, B and C (lowest priority).
Tip: Assign Job ClassA to system jobs (basis, warehouse and maintenance jobs in SAP executed by system administrators), as these are prerequisites for all other jobs to run smoothly.
