• What is the cause and solution for SAP error message /SAPAPO/BLRG049 - System ignoring block number(s); block number(s) issued already ?

  The SAP error message /SAPAPO/BLRG049 System ignoring block number(s); block number(s) issued already typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an issue with the processing of blocks in the system. This error indicates that the system has received block numbers that it has already processed, leading to a situation where it ignores the duplicate block numbers.
  Cause:
  
  
  Duplicate Block Numbers: The most common cause of this error is that the same block number is being sent multiple times to the system. This can happen due to:
  
  A retry mechanism in the application that resends the same block number.
  A misconfiguration in the integration between systems (e.g., between SAP ERP and SAP APO).
  Network issues causing the same request to be sent multiple times.
  
  
  
  Concurrency Issues: If multiple processes are trying to process the same block simultaneously, it can lead to this error.
  
  
  System Configuration: Incorrect settings in the APO system or in the integration settings can also lead to this issue.
  
  
  Solution:
  
  
  Check for Duplicate Requests: Investigate the source of the block numbers being sent to the system. Ensure that the application or process generating these block numbers is not sending duplicates.
  
  
  Review Integration Settings: If the error is occurring due to integration between systems (e.g., SAP ERP and SAP APO), review the configuration settings to ensure that they are set up correctly and that there are no issues causing duplicate messages.
  
  
  Error Handling Logic: Implement error handling logic in the application that generates the block numbers to avoid resending the same block number if it has already been processed.
  
  
  Monitor and Log: Enable logging for the processes that generate and send block numbers. This can help identify patterns or specific conditions under which duplicates are being sent.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  System Performance: Ensure that the system is performing optimally and that there are no performance bottlenecks that could lead to delays in processing, which might cause retries.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for APO and the specific modules you are using to understand how block processing works.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
