  The SAP error message PR237, which states "You are changing an existing data record," typically occurs in the context of data entry or modification in SAP, particularly when dealing with master data records such as vendor, customer, or material records. This error indicates that the system has detected an attempt to change a record that is already existing in the database, and it may be due to various reasons.
  Causes:
  
  Duplicate Entry: You might be trying to create a new record with the same key as an existing record.

  Check for Duplicates: Verify if the record you are trying to create already exists. If it does, you may need to update the existing record instead of creating a new one.
  Use the Correct Transaction: Ensure you are using the correct transaction code for updating existing records (e.g., using MM02 for material master updates instead of MM01 for creation).
  Review Authorizations: Check your user authorizations to ensure you have the necessary permissions to modify the record.
  Check for Locks: Use transaction SM12 to check if the record is locked by another user. If it is, you may need to wait until the lock is released.
