when the program runs, use export statement.

EXPORT <value > to memory ID 'MEM_PROG_RUN'

and in the code check the value of the memory to see if the program is already running

Hi,

You can use the below code:

If not sy-batch is initial.

read the select options to an internal table.

use describe statement to get the no. of entries in Internal table.

if no. of items in itab is more than 1.

use stop.

Thanks,

Hi Ming,

What you can probably try is to lock the Company Code object at the start of the code(Start of selection)

ENQUEUE_ECOP_BUKRS

and at the end of the program deque it using DEQUEUE_ECOP_BUKRS.

at you selection screen, you can validate if the company code are not locked using the same FM: ENQUEUE_ECOP_BUKRS. If it is not locked, you can proceed . Else you can raise an error.
