Hi,

I think using SM01 you can lock the required transaction code.

Hi Ahmed,

By default sap locks a transaction when it is open for 1 user. so you don't have to do anything.

At one time a single user can change/edit a tcode.

hope this solves your doubt.

Hi,

If one user is using a tcode that is if he is editing or changing the things, then it will be automatically locked for other users for editing/changing, the other users can able to see the tcode in display mode only.

If you want to use the tcode especially for you, then ask concern basis for giving authorizations to the tcode and you can alone only able to use that tcode.

As others specified, if it is a standard transaction, then he locking is taken care of already.

If you want to lock your own(Custom transaction).

You have to create lock objects in SE11 transaction.

Then two (ENQUE_your object and DEQUE_your object ) function modules are generated.

You have to use one fm at the start of your transaction and the other at the end.

Hi,

We can do it through programmatically as well.

Check this code,

tables: tstc.

* To lock the Tcode
update tstc SET cinfo = 'A0'
          WHERE tcode = 'VA01'.

IF sy-subrc = 0.
  COMMIT WORK.
endif.

thanks\
