  SAP Error Message:
  WXP773 Unexpected return code &1 for FB 'ENWUEUE_E_WISP_PLSZN'
  
  1. Cause
  
  The error message WXP773 indicates that a function module (FB) call returned an unexpected return code.
  In this case, the function module (or function block) is 'ENWUEUE_E_WISP_PLSZN'.
  The placeholder &1 is replaced by the actual return code received, which is not the expected one.
  This usually happens when a function module or a remote-enabled function module (RFC) returns an error or an unexpected status that the calling program does not handle.
  The function module 'ENWUEUE_E_WISP_PLSZN' is related to SAP Workflow or SAP PI/PO (Process Integration/Process Orchestration), specifically in the context of queue processing or message handling.
  The unexpected return code could be due to:
  
  Communication issues (e.g., RFC destination not reachable).
  Incorrect parameters passed to the function module.
  Backend system errors or inconsistencies.
  Authorization or system configuration problems.
  Queue or message processing errors.
