Budget control system

Hi Experts,

I am new to BCS ( Budget control system) , I have a doubt in update profile. I am using update profile 0350 which is updating commitment as well as payment budget when i create PR ( purchase requisation and Purchase order)

My scenario is that when i create PR and PO , this is to be update commitment budget at the same time no need to update payment budget.

Can any one update me how to resolve this issue.

Thanks & Regards,

Y.Kiran Babu.
