  Programming Errors: Custom programs or modifications that interact with the locking mechanism may inadvertently create lock keys with incorrect lengths.
  
  Solution:
  
  Check Lock Key Generation: Review the code or configuration that generates the lock keys. Ensure that it adheres to the expected length and format. This may involve checking custom ABAP programs or configurations in the system.
  Clear Locks: If the locks are not needed, you can manually clear them using transaction codes like SM12 (for lock entries) to delete any orphaned or incorrect lock entries.
