I need some guide how to lock custom function e.g Z_FUNC_CALSALR, the scenario will be like this:

When ever user run program A that call this function , other user which also running Program B that call this function will be paused until the function release from lock status.

Hi,

Maybe you could be use a parameter Ztable.

The FM Z_FUNC_CALSALR set a flag on this table at start and reset this flag at end.

Program B has to check this flag to know if the function is running.

Hi,

Use FM:RS_ACCESS_PERMISSION to lock/Unlock your custom function module,once your function module get locked any other person could not suppose to use the same so throw a message in this case ,after every call Unlock it agian by calling same function module.

Thaks and regards,

If you want to lock a function module then you have two use these two function modules

DEQUEUE_ESFUNCTION

ENQUEUE_ESFUNCTION

Pass FUNCNAME = you function module name to ENQUEUE_ESFUNCTION for locking and DEQUEUE_ESFUNCTION for unclocking.

Use these functions in your function module or outside it as required.
