• What is the cause and solution for SAP error message W_MD029 - Temporary data generated while collective PO was created has been deleted ?

  The SAP error message W_MD029 indicates that temporary data generated during the creation of a collective purchase order (PO) has been deleted. This message typically arises in the context of the Materials Management (MM) module when there are issues related to the processing of collective POs.
  Cause:
  
  
  Temporary Data Deletion: The error suggests that the temporary data required for processing the collective PO was deleted before the system could complete the operation. This can happen due to various reasons, such as:
  
  A timeout or session expiration.
  An unexpected termination of the transaction.
  Manual deletion of temporary data by a user or system process.
  System configuration issues or bugs.
  
  
  
  Data Consistency Issues: If there are inconsistencies in the data being processed (e.g., missing or incorrect master data), it may lead to the deletion of temporary data.
  
  
  System Performance: If the system is under heavy load or if there are performance issues, it may not be able to handle the temporary data correctly.
  
  
  Solution:
  
  
  Retry the Operation: Often, simply retrying the operation can resolve the issue, especially if it was caused by a temporary glitch.
  
  
  Check for Session Timeouts: Ensure that your session is active and not timing out during the operation. If necessary, adjust the timeout settings in the SAP system.
  
  
  Review System Logs: Check the system logs (transaction SLG1) for any related error messages or warnings that could provide more context about why the temporary data was deleted.
  
  
  Data Consistency Check: Verify that all necessary master data (vendors, materials, etc.) is correctly set up and consistent. You can use transaction codes like ME1M (Vendor Material Info Record) to check for inconsistencies.
  
  
  Performance Monitoring: Monitor system performance to ensure that it is not overloaded. If performance issues are identified, consider optimizing the system or scheduling heavy operations during off-peak hours.
