• What is the cause and solution for SAP error message WS_MASS007 - Choose start after event or immediate start ?

  SAP Error Message:
  
  WS_MASS007: Choose start after event or immediate start
  
  Cause:
  This error occurs when you are trying to schedule a workflow or a mass workflow start in SAP, but you have not specified the start time correctly. The system requires you to choose whether the workflow should start immediately or after a specific event. If neither option is selected, the system raises this error.
  In other words, the workflow start parameters are incomplete or inconsistent — the system needs a clear instruction on when to trigger the workflow.
  
  When does it occur?
  
  When starting workflows via transaction SWUS (Mass Workflow Start).
  When scheduling workflows in background jobs or via workflow templates.
  When configuring workflow start conditions and the start time is not properly set.
  
  
  Solution:
  
  
  Specify the Start Time Correctly:
  
  In the workflow start screen (e.g., SWUS), ensure you select either:
  
  Immediate start (start the workflow immediately), or
  Start after event (choose the event that triggers the workflow start).
  
  
  
  
  
  Check the Workflow Start Parameters:
  
  If you are using a custom program or BAPI to start workflows, verify that the parameters related to start time or event are correctly filled.
  
  
  
  Review Workflow Template:
  
  If the workflow is triggered by an event, ensure the event is properly defined and linked to the workflow.
  
  
  
  In Mass Workflow Start (SWUS):
  
  When you select workflows to start, the system prompts for start options. Make sure to select one of the options:
  
  Immediate start
  Start after event (and specify the event)
  
  
  
  
  
  If using background jobs:
  
  Check the job scheduling parameters to ensure the workflow start time is defined.
  
  
  
  
  Additional Information:
  
  Transaction SWUS is commonly used for mass starting workflows.
  The error message is a safeguard to prevent workflows from being started without a clear trigger.
  If you want the workflow to start immediately, simply select the immediate start option.
  If the workflow depends on an event (e.g., creation of a purchase order), select the event start option and specify the event.
  This message helps avoid workflows being stuck in an undefined state.
