Object Collision Message Not Appearing

[sanjay_ram]

Hi,

In our config client 2 consultants tried to change the same object in OBA1 t.code but the standard transport object collision message is not appearing.

Is there any BASIS settings required to turn this checking on?

Hello Sanjay,

Applications must lock objects as needed. This should be part of the ABAP code of the application.

Nothing on basis level defines the locking logic of the applications.
