  SAP Error Message:
  WXP823 Unexpected return code &1 for FB WIS_PLAN_DISP_INTERF_LOG
  
  Meaning / Cause:
  
  This error occurs during the execution of a function module (FB) named WIS_PLAN_DISP_INTERF_LOG.
  The message indicates that the function module returned an unexpected return code (the placeholder &1 is replaced by the actual return code).
  Typically, this means that the function module encountered an issue or exception that it did not handle as expected.
  The function module WIS_PLAN_DISP_INTERF_LOG is related to the SAP Business Warehouse (BW) or SAP Logistics Information System (LIS), specifically dealing with planning and dispatch interface logging.
  The unexpected return code could be due to:
  
  Incorrect or missing input parameters.
  Data inconsistencies.
  Authorization issues.
  System or interface communication problems.
  Custom enhancements or user-exits causing unexpected behavior.
  
  
  
  
  Common Causes:
  
  Incorrect Input Data: The data passed to the function module might be incomplete or invalid.
  Authorization Issues: The user executing the function might lack necessary authorizations.
  Interface or Communication Errors: If the function module interacts with external systems or interfaces, communication failures can cause unexpected return codes.
  System or Configuration Issues: Missing or incorrect configuration in LIS or BW planning interfaces.
  Custom Code or Enhancements: Modifications or user-exits might cause the function module to behave unexpectedly.
  
  
  Solution / Troubleshooting Steps:
  
  
  Check the Return Code:
  
  Identify the actual return code (&1) from the error message.
  Look up what this return code means in the context of the function module or SAP documentation.
