• What is the cause and solution for SAP error message WE021 - Choose one processing option only ?

  SAP Error Message:
  
  WE021 - Choose one processing option only
  
  Cause:
  This error occurs during IDoc processing when more than one processing option is selected simultaneously for an inbound or outbound IDoc. SAP requires that only one processing option be chosen at a time to avoid conflicts in how the IDoc is handled.
  For example, when processing an inbound IDoc, you might have options like:
  
  Process immediately
  Collect and process later
  Archive only
  
  If more than one of these options is selected at the same time, the system throws the WE021 error.
  
  When does it occur?
  
  During inbound IDoc processing (transaction WE19, WE02, WE05, or background processing).
  When manually processing IDocs and selecting processing options.
  When the partner profile (WE20) is configured with conflicting processing options.
  When using transaction BD87 (Inbound IDoc processing) and multiple options are selected.
  
  
  Solution:
  
  
  Check Processing Options:
  
  Ensure that only one processing option is selected for the IDoc processing.
  For example, if you are processing IDocs in transaction BD87, select only one of the options such as "Process immediately" or "Collect and process later," but not both.
  
  
  
  Review Partner Profile Settings (WE20):
  
  Go to transaction WE20.
  Check the inbound parameters for the partner.
  Make sure that only one processing option is set for inbound processing (e.g., either "Trigger immediately" or "Collect and process later").
  
  
  
  Check Custom Programs or User Exits:
  
  If you have custom code or user exits that set processing options programmatically, verify that they do not set conflicting options.
  
  
  
  Use Standard Transactions Correctly:
  
  When using WE19 (Test tool for IDocs), ensure that only one processing option is selected before triggering processing.
  
  
  
  
  Additional Information:
  
  
  Transaction Codes:
  
  WE20: Partner Profiles (to configure processing options)
  WE19: Test tool for IDocs
  BD87: Inbound IDoc processing
  WE02 / WE05: IDoc display and monitoring
  
  
  
  SAP Notes:
  
  Check SAP Notes related to WE021 for any specific patches or updates.
  
  
  
  Documentation:
  
  SAP Help Portal and IDoc processing guides explain the processing options in detail.
  
  
  
  
  Summary:
  WE021 error means multiple processing options were selected simultaneously for an IDoc. To fix it, select only one processing option either in the partner profile or during manual processing.
