• What is the cause and solution for SAP error message SWF_EXP_001181 - Mandatory parameter missing ?

  The SAP error message SWF_EXP_001181 indicates that a mandatory parameter is missing in the context of workflow execution. This error typically arises when a workflow is triggered without all the required parameters being provided, which can prevent the workflow from executing correctly.
  Cause:
  
  Missing Parameters: The most common cause is that the workflow is expecting certain parameters to be passed to it, but they are not being provided. This can happen if the workflow is called programmatically or through a transaction that does not supply all necessary data.
  Configuration Issues: There may be issues in the workflow configuration where the mandatory parameters are not defined correctly.
  Custom Development: If there are custom workflows or enhancements, they may not be handling parameters correctly.
  
  Solution:
  
  Check Workflow Definition: Review the workflow definition in the SAP Business Workflow (transaction code SWDD). Ensure that all mandatory parameters are defined and that they are being passed correctly when the workflow is initiated.
  Parameter Mapping: If the workflow is triggered from a custom program or transaction, ensure that all required parameters are being passed correctly. You may need to check the code to ensure that the parameters are being populated.
  Debugging: Use transaction SWI1 (Work Item Selection) to find the work item that generated the error. You can analyze the workflow instance and check the logs for more details on which parameter is missing.
  Check Workflow Logs: Use transaction SWI6 to view the workflow logs and identify which parameters are missing. This can provide insight into what needs to be corrected.
  Consult Documentation: If the workflow is part of a standard SAP process, refer to the relevant SAP documentation or notes for any specific requirements regarding parameters.
  Testing: After making changes, test the workflow to ensure that it executes without errors.
