  Communicate with Team Members: If you are working in a collaborative environment, communicate with your team to understand what changes were made to the object.
  Check for Locks: Use transaction codes like SM12 to check for locks on the object. If you find that another user has locked the object, you may need to wait until they release it.
  Error Handling: Implement error handling in your processes to manage such conflicts gracefully, possibly by notifying users when their changes cannot be saved due to concurrent modifications.
