• What is the cause and solution for SAP error message BUP_RELATIONS145 - Multiple changes to time-dep. relship record not permitted (roundtrip) ?

  The SAP error message BUP_RELATIONS145 indicates that there are multiple changes being attempted on a time-dependent relationship record in a roundtrip scenario, which is not permitted. This typically occurs when you are trying to update a business partner's relationships in a way that conflicts with the system's rules for handling time-dependent data.
  Cause:
  
  Concurrent Changes: The error often arises when multiple changes are being made to the same relationship record simultaneously, either in the same session or across different sessions.
  Time Dependency: The relationship record is time-dependent, meaning it has specific validity periods. If changes are attempted that overlap or conflict with existing records, the system will prevent these changes to maintain data integrity.
  Roundtrip Processing: This refers to the process of sending data back and forth between the SAP system and an external system or interface. If the external system sends conflicting updates, it can trigger this error.
  
  Solution:
  
  Check for Concurrent Sessions: Ensure that no other sessions or users are trying to modify the same relationship record at the same time. If possible, coordinate changes to avoid conflicts.
  Review Time Validity: Check the validity periods of the relationship records you are trying to change. Ensure that the changes you are making do not overlap with existing records.
  Batch Processing: If you are processing multiple changes in a batch, consider breaking them down into smaller batches to avoid conflicts.
  Error Handling in Interfaces: If this error arises from an interface or external system, implement error handling to manage conflicts and ensure that only valid changes are sent to SAP.
  Consult Documentation: Review SAP documentation or notes related to business partner relationships and time-dependent data to understand the specific rules and constraints.
  
  Related Information:
  
  Transaction Codes: You may want to check the relevant transaction codes for managing business partner relationships, such as BP (Business Partner) or BP_REL (Business Partner Relationships).
  SAP Notes: Look for SAP Notes that may address this specific error or provide additional guidance on handling time-dependent relationships.
  Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance, especially if this is affecting business operations.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
