• What is the cause and solution for SAP error message FARR_CONTRACT_MAIN129 - Event type of POB &1 must be the same as its leading POB ?

  The SAP error message FARR_CONTRACT_MAIN129 typically occurs in the context of contract management, particularly when dealing with Purchase Order (POB) events in the SAP system. This error indicates that there is a mismatch in the event types of the POB and its leading POB. 
  Cause:
  The error arises when the event type of a subordinate POB does not match the event type of its leading POB. In SAP, a leading POB is the primary document that governs the subordinate POBs. For example, if the leading POB is of type "A," then all subordinate POBs must also be of type "A." This ensures consistency in the processing of related documents.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Event Types: Review the event types of both the leading POB and the subordinate POB. Ensure that they match. You can do this by navigating to the relevant transaction in SAP where you can view the details of the POBs.
  
  
  Adjust Event Types: If you find that the event types do not match, you will need to adjust the event type of the subordinate POB to match that of the leading POB. This may involve changing the configuration or the data entry for the subordinate POB.
  
  
  Consult Documentation: Refer to the SAP documentation or help files related to contract management and POB processing for specific instructions on how to change event types.
  
  
  Check Customizations: If your organization has custom developments or configurations in place, ensure that these do not interfere with the standard behavior of POB event types.
  
  
  Testing: After making the necessary adjustments, test the process again to ensure that the error is resolved and that the POBs are processed correctly.
