• What is the cause and solution for SAP error message /SAPAPO/RSP773 - Release has already been started ?

  The SAP error message /SAPAPO/RSP773 Release has already been started typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an attempt to start a release process that has already been initiated. This can happen in various scenarios, such as during the planning or execution of a release in the Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS) modules.
  Cause:
  
  Duplicate Release Attempt: The most common cause is that a release process (like a planning run or a heuristic) is already in progress for the same planning object or data set.
  System Locking: The system may have a lock on the data due to the ongoing process, preventing another instance from starting.
  User Error: A user may have inadvertently tried to start the same process multiple times.
  
  Solution:
  
  
  Check Running Processes: 
  
  Use transaction codes like SM37 (Job Monitoring) to check if there are any jobs currently running that correspond to the release you are trying to start.
  If you find a job that is still running, you may need to wait for it to complete or, if necessary, terminate it if it is stuck.
  
  
  
  Review Lock Entries:
  
  Use transaction SM12 to check for any lock entries related to the release process. If you find locks that are no longer needed, you can delete them (ensure you have the necessary authorizations and that it is safe to do so).
  
  
  
  Wait for Completion: If the process is legitimate and running, simply wait for it to complete before attempting to start the release again.
  
  
  Check for Errors: If the previous release process has failed, check the logs for any errors that may have caused it to hang or not complete properly.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific release process you are working with for any additional troubleshooting steps or known issues.
  
  
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team or SAP support channels for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM37 for job monitoring, SM12 for lock entries, and SLG1 for application logs.
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message.
  System Performance: Sometimes, system performance issues can lead to processes taking longer than expected, which may cause confusion regarding whether a process is still running or has failed.
  
  By following these steps, you should be able to resolve the /SAPAPO/RSP773 Release has already been started error and successfully manage your release processes in SAP APO.
