Procedure doesn't work when called using button

Hello All.
I have two procedures, autocreate_delivery and transact_move_order.
I wanna call each procedure using different button.
When i called procedure autocreate_delivery using when-button-pressed trigger, it worked properly.
When i called procedure transact_move_order, it didnt work, but it worked well when i ran it using oracle sql developer.
I didnt find any error message.
Anybody can help me?

Thanks in advance
