• What is the cause and solution for SAP error message CRM_PS_ACTIVITY017 - Leading Transaction GUID is mandatory when FM is called in event callback ?

  The SAP error message CRM_PS_ACTIVITY017 indicates that a Leading Transaction GUID (Globally Unique Identifier) is mandatory when a Function Module (FM) is called in an event callback. This error typically occurs in the context of SAP CRM (Customer Relationship Management) when dealing with activities or transactions that require a unique identifier to track the context of the operation.
  Cause:
  The error is triggered when:
  
  A function module is invoked in an event callback without providing the necessary Leading Transaction GUID.
  The system expects a GUID to identify the transaction context, but it is either missing or not correctly passed to the function module.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Function Module Call: Ensure that when you are calling the function module in the event callback, you are passing the Leading Transaction GUID correctly. This might involve checking the parameters being passed to the FM.
  
  
  Identify the Source of the GUID: Determine where the Leading Transaction GUID should be sourced from. It may be available from the context of the event or may need to be retrieved from a previous transaction.
  
  
  Modify the Event Callback Logic: If the GUID is not being passed correctly, you may need to modify the logic in your event callback to ensure that the GUID is included in the function module call.
  
  
  Debugging: If you are unsure where the issue lies, consider debugging the event callback to see the values being passed and identify where the GUID is missing.
  
  
  Consult Documentation: Review the SAP documentation for the specific function module you are using to understand the required parameters and their significance.
  
  
  Check Custom Code: If you have custom code that interacts with standard SAP function modules, ensure that it adheres to the expected input parameters, including the Leading Transaction GUID.
