SAP Business Workflow - Function Modules

Function modules are sub-programs that contain a set of reusable statements with importing and exporting parameters. Unlike Include programs, function modules can be executed independently. SAP system contains several predefined function modules that can be called from any ABAP program. The function group acts as a kind of container for a number of function modules that would logically belong together. For instance, the function modules for an HR payroll system would be put together into a function group.

Following Function modules can be used in the workflow in SAP system −

  • SWW_WI_CONTAINER_READ − This function module is used to read the container elements in SAP workflow.

  • SWW_WI_ENABLE − This is used for unlocking of workitems against execution.

  • SWW_WI_DISABLE − This function module is used for locking workitems for execution.
