• What is the cause and solution for SAP error message WFRE_CON200 - ******** 200 - 250 Messages for reference module interface ******** ?

  The SAP error message WFRE_CON200 with the text pattern like:
  ********  200 - 250  Messages for reference module interface  ********
  is related to the Workflow Runtime Engine (WFRE) and typically occurs in the context of workflow processing, especially when there are issues with the reference module interface or communication between workflow components.
  
  Cause
  
  Reference Module Interface Issues: The error usually indicates that there are problems in the communication or message exchange between the workflow runtime engine and the reference module interface.
  Message Queue or Buffer Problems: The workflow runtime engine uses message queues to communicate with different modules. If these queues are full, corrupted, or messages are not processed correctly, this error can occur.
  Configuration or Transport Issues: Incorrect configuration of workflow components or transport inconsistencies can cause this error.
  Authorization or System Resource Issues: Sometimes, insufficient authorizations or system resource constraints (memory, buffer sizes) can lead to this error.
  Version or Patch Level Mismatch: If the workflow runtime engine and the reference module interface are on different patch levels or incompatible versions, communication errors may arise.
  
  
  Solution
  
  
  Check Workflow Logs and Traces:
  
  Use transaction SWI1 (Workflow Log) to check the detailed workflow logs for errors.
  Use transaction ST22 to check for any dumps related to workflow runtime.
  Use transaction SMQ1 and SMQ2 to check outbound and inbound queues for stuck or failed messages.
  
  
  
  Check and Clear Workflow Queues:
  
  If queues are stuck or full, try to process or clear them.
  Use transaction SWU3 to check workflow configuration and fix inconsistencies.
  
  
  
  Verify Configuration:
  
  Run SWU3 (Workflow Customizing) to check and correct workflow configuration.
  Check the settings of the reference module interface in the workflow customizing.
  
  
  
  Check Authorization:
  
  Ensure that the user running the workflow has the necessary authorizations.
  
  
  
  Apply SAP Notes:
  
  Search for SAP Notes related to WFRE_CON200 or workflow runtime errors.
  Apply relevant patches or corrections as recommended by SAP.
  
  
  
  System Resources:
  
  Check system logs (transaction SM21) for resource-related errors.
  Increase buffer sizes or memory if needed.
  
  
  
  Restart Workflow Runtime:
  
  Sometimes restarting the workflow runtime engine or the related work processes can resolve transient issues.
