transaction code

[Former Member]

Hi friends,

I am working on a module pool program.

I need to know how to lock the transaction ( ztransaction - the transaction code created for my module pool program) .

I need to know how to make the transaction to be used only by a single user at a time.

please help me out with some logic.

Thanks in advance.

use meaningful subject for your questions

You can try this method, but i am not sure, this is the right approach.

Create a ZTABLE.

When somebody executes the transaction for the first time, create a entry in the ZTABLE and while coming out of transaction delete the entry from ZTABLE.

When somebody else executes the transaction, check whether entry is available in the ZTABLE, if yes, than give error message, else proceed with the transaction

Hi,

Use Enqueue and dequeue Lock function modules to lock the transaction from the user.

TO do so first you have to create a lock object in se11.

and use this lock object in the program.

Use Enqueue function modules to lock the TCODE and once you come to out of the transaction use dequeue function module to unlock the TCODE.
