• What is the cause and solution for SAP error message /PLMI/GSS_R2X061 - Loading is not possible; synch. unit has already been synchronized ?

  The SAP error message /PLMI/GSS_R2X061 Loading is not possible; synch. unit has already been synchronized typically occurs in the context of SAP's Logistics Execution (LE) or Production Planning (PP) modules, particularly when dealing with synchronization units in the context of goods movements or production orders.
  Cause:
  This error indicates that the synchronization unit you are trying to load has already been synchronized. This can happen due to several reasons:
  
  Duplicate Synchronization: The synchronization unit has already been processed or synchronized in a previous operation, and the system does not allow reloading it.
  Incorrect Process Flow: The process flow may not be followed correctly, leading to attempts to synchronize a unit that is already in a synchronized state.
  System Configuration: There may be configuration settings in the system that prevent reloading of already synchronized units.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Synchronization Status: Verify the status of the synchronization unit in the system. Ensure that it is indeed in a synchronized state and check if any further actions are required.
  
  
  Review Process Flow: Ensure that you are following the correct process flow for loading or synchronizing units. If you are trying to perform an operation that is not allowed at this stage, adjust your process accordingly.
  
  
  Consult Logs: Check the application logs or transaction logs for any additional error messages or warnings that might provide more context about why the synchronization unit cannot be loaded.
  
  
  Revert Changes: If the synchronization was performed in error, you may need to revert the changes or unsynchronize the unit if the system allows it.
  
  
  Configuration Review: If the issue persists, review the configuration settings related to synchronization units in your SAP system. Consult with your SAP Basis or functional team to ensure that the settings are appropriate for your business processes.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error message. There may be patches or updates that resolve known issues.

  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes that may help in monitoring or managing synchronization units, such as LB10 (for loading), COHV (for production order handling), or VL01N (for creating outbound deliveries).
  Documentation: Review SAP documentation related to Logistics Execution and Production Planning for best practices on handling synchronization units.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
