  Check Naming Conventions: Ensure that the name of the lock parameter adheres to SAP's naming conventions. Typically, names should be alphanumeric and should not contain special characters or spaces.
  Review Lock Object Definition: Go to transaction SE11 (Data Dictionary) and check the definition of the lock object. Ensure that all parameters are correctly defined and that their data types match what is being passed in the code.
