• What is the cause and solution for SAP error message /PLMB/BA_GSS214 - External key &1 of synchronization must not be changed to &2 ?

  The SAP error message /PLMB/BA_GSS214 typically relates to issues with synchronization in the context of SAP PLM (Product Lifecycle Management) or similar modules where external keys are used for data synchronization between systems or components.
  Cause:
  The error message indicates that there is an attempt to change an external key from one value (&1) to another value (&2). This is not allowed because the external key is expected to remain constant for synchronization purposes. Changing the external key can lead to inconsistencies in data synchronization, as the system relies on these keys to match records across different systems or datasets.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Identify the Source of Change: Determine where the change to the external key is being initiated. This could be from a manual update, a data import, or a system process.
  
  
  Review Business Logic: Check the business logic or process that is attempting to change the external key. Ensure that it is designed to maintain the integrity of the external key.
  
  
  Correct the Data: If the change is not intended, revert the external key back to its original value. If the change is necessary, you may need to review the synchronization logic to ensure that it can handle such changes appropriately.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific module you are working with. There may be specific guidelines or configurations that need to be followed.
  
  
  Check for Custom Code: If there is any custom code or enhancements in your SAP system that might be affecting the external key, review and adjust it as necessary.
  
  
  Testing: After making the necessary changes, test the synchronization process to ensure that it works without errors.
  
  
  Related Information:

  User Roles and Permissions: Ensure that the user roles and permissions are correctly set up, as unauthorized changes to external keys may trigger this error.
