  Use New Syntax: Replace the old lock key definitions with the new syntax as recommended in the SAP documentation. This may involve changing how the lock keys are declared or used in your programs.
  Testing: After making changes, thoroughly test the affected programs to ensure that they function correctly and that the lock mechanisms work as intended.
