• What is the cause and solution for SAP error message /SAPAPO/OM_SYNC020 - RPM inconsistent or RPMCALL started ?

  The SAP error message /SAPAPO/OM_SYNC020 RPM inconsistent or RPMCALL started typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an inconsistency in the Resource Planning Module (RPM) or when a call to the RPM is already in progress. This can happen during various operations, such as planning runs or when trying to access certain functionalities within the APO system.
  Causes:
  
  Inconsistent Data: The RPM may have inconsistent data due to previous failed operations or incomplete transactions.
  Concurrent Processes: Another process may be running that is accessing the RPM, leading to a lock or conflict.
  System Configuration Issues: There may be configuration issues within the APO system that are causing the RPM to behave unexpectedly.
  Database Locks: Database locks on the RPM tables can prevent new operations from being executed.
  
  Solutions:
  
  
  Check for Running Processes: Use transaction codes like SM66 or SM50 to check if there are any active processes that are currently using the RPM. If you find any, you may need to wait for them to complete or terminate them if they are stuck.
  
  
  Consistency Check: Perform a consistency check on the RPM data. You can use transaction /SAPAPO/RPM_CHECK to identify and resolve inconsistencies.
  
  
  Restart the RPM: If the RPM is in a locked state, you may need to restart it. This can often be done by executing the relevant transaction or program that initializes the RPM.
  
  
  Review Logs: Check the application logs (transaction SLG1) for any additional error messages or warnings that could provide more context on the issue.
  
  
  Database Administration: If you suspect database locks, you may need to work with your database administrator to identify and resolve any locks that are preventing access to the RPM.
  
  
  System Configuration Review: Review the configuration settings for the RPM in the APO system to ensure that everything is set up correctly.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message. There may be patches or updates that resolve known issues.
