I'm having a situation here that i would need your help.
From IW51 i'll create a sales order VA01 and just before creation i would need to do some validation on the plant and service center and then change the Ship-to-party value to another.
I am not sure on which exit or badi offers that functions. the ones that i've found is EXIT_SAPLV46H_002 and EXIT_SAPLV09A_004. Both of this doesn't work.
If any one of you has encountered this problem and manage to resolve it please help me resolve mine as well.
