• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR2042 - Synchronization not allowed ?

  The SAP error message /SAPAPO/OM_ERROR2042: Synchronization not allowed typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an attempt to synchronize data that is not permitted due to certain conditions or settings in the system.
  Cause:
  
  
  Data Locking: The error may arise if the data you are trying to synchronize is currently locked by another process or user. This can happen if another transaction is being processed that involves the same data.
  
  
  Configuration Settings: There may be specific configuration settings in the APO system that restrict synchronization under certain conditions. For example, if the planning area is set to not allow synchronization for certain data types or during specific time frames.
  
  
  Inconsistent Data: If there are inconsistencies in the data between the APO and the connected systems (like SAP ERP), the synchronization may be blocked to prevent further issues.
  
  
  User Authorizations: The user attempting the synchronization may not have the necessary authorizations to perform the action.
  
  
  Solution:
  
  
  Check Data Locks: Investigate if there are any active locks on the data you are trying to synchronize. You can use transaction codes like SM12 to check for locks and SM21 for system logs.
  
  
  Review Configuration: Check the configuration settings in the APO system to ensure that synchronization is allowed for the specific planning area and data types you are working with. This may involve reviewing the settings in the planning area configuration.
  
  
  Data Consistency Check: Perform a consistency check between the APO and the connected systems. You can use transaction /SAPAPO/CONSISTENCY_CHECK to identify and resolve any inconsistencies.
  
  
  User Authorizations: Ensure that the user has the necessary authorizations to perform synchronization. This may involve checking roles and permissions assigned to the user in the SAP system.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to this specific error message for any additional troubleshooting steps or patches that may be required.
