  Error Message
  WPLG009: Call module is not maintained; see long text
  
  Cause
  This error occurs in SAP Workflow when the system tries to execute a call module (a function module or a method) that has not been properly maintained or configured in the workflow customizing. Essentially, the workflow is trying to call a module that either:
  
  Has not been assigned in the workflow customizing,
  The module name is incorrect or missing,
  Or the call module configuration is incomplete or missing in the relevant workflow container or task.
  
  
  When does it occur?
  
  During workflow execution, especially when a step involves calling a function module or method.
  When the workflow step is configured to call a module, but the module is not maintained in the workflow customizing.
  When the workflow container or task does not have the required call module assigned.
  
  
  Solution
  
  
  Check Workflow Customizing:
  
  Go to transaction SWDD (Workflow Builder).
  Open the workflow and locate the step that causes the error.
  Check the Method/Function Module assigned to the step.
  Ensure that the call module is correctly maintained and assigned.
  
  
  
  Maintain Call Module in Workflow:
  
  Use transaction SWO1 to check the Business Object and its methods.
  Verify that the method or function module is correctly defined and active.
  If a function module is called directly, ensure it is maintained in the workflow customizing.
  
  
  
  Check Workflow Container:
  
  Verify that the workflow container has the necessary data elements and that the call module is correctly linked to the container elements.
  
  
  
  Check for Missing or Incorrect Module Name:
  
  Sometimes the module name might be misspelled or missing.
  Correct the module name in the workflow step.
  
  
  
  Transport and System Consistency:
  
  If the workflow was transported from another system, ensure that all related objects (function modules, methods, etc.) are also transported and active.
  
  
  
  Activate the Workflow:
  
  After making changes, activate the workflow and test again.
  
  
  
  
  Additional Information
  
  
  Transaction Codes:
  
  SWDD - Workflow Builder
  SWO1 - Business Object Builder
  SWI1 - Workflow Log (to analyze workflow errors)
  SWU3 - Workflow Customizing (to check workflow settings)
  
  
  
  Related Notes and Documentation:
  
  SAP Notes related to workflow errors often provide guidance on call module maintenance.
  Check SAP Help Portal for workflow configuration and call module assignment.
  
  
  
  Debugging:
  
  Use the workflow log (transaction SWI1) to identify the exact step causing the error.
  Debug the workflow step to see which module is being called and why it is not maintained.
  
  
  
  
  Summary
  
  
  
  Aspect
  Description
  
  
  
  
  Cause
  Workflow step calls a module (function module/method) not maintained or incorrectly assigned.
  
  
  Solution
  Maintain the call module correctly in workflow customizing (SWDD, SWO1), check container and module names, activate workflow.
  
  
  Related Info
  Use SWI1 for logs, SWU3 for customizing checks, ensure transport consistency.
