• What is the cause and solution for SAP error message /SMB/DEFINITION031 - Illegal call: GUID may not be changed ?

  The SAP error message /SMB/DEFINITION031 Illegal call: GUID may not be changed typically occurs in the context of SAP Business One or related applications that utilize GUIDs (Globally Unique Identifiers) for object identification. This error indicates that there is an attempt to modify a GUID, which is not allowed since GUIDs are meant to uniquely identify records and should remain constant once assigned.
  Cause:
  
  
  Modification Attempt: The most common cause of this error is an attempt to change the GUID of an existing object or record in the database. This can happen due to:
  
  Custom code or scripts that incorrectly attempt to update the GUID.
  Data migration processes that improperly handle GUIDs.
  Manual changes in the database that violate the integrity of the GUID.
  
  
  
  System Configuration Issues: Sometimes, configuration issues or bugs in the system can lead to this error, especially if there are inconsistencies in how GUIDs are generated or managed.
  
  
  Solution:
  
  
  Review Custom Code: If you have custom code or scripts that interact with the database, review them to ensure that they do not attempt to modify GUIDs. Ensure that any operations involving GUIDs are read-only.
  
  
  Data Migration: If this error occurs during a data migration process, ensure that the migration scripts or tools are correctly handling GUIDs. They should not attempt to change existing GUIDs.
  
  
  Database Integrity: Check the database for any manual changes that may have been made to GUID fields. If changes were made, revert them to their original values.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidelines on handling GUIDs in your version of SAP Business One or related applications.
