Control Delivery split based on diff in exchange rate (let. of credit)

Hi Team,

We have a scenarios where the user does nto want split in delivery because of differecne in Exchange rate for line items.

In my case when Letter of credit si assigned to line item.

I understand this as standard behavior that a delivery splits happens based on difference in exchangerate.

My question is to control this split, will it be a right to control it by routine in copy controls routine form order to delivery or we consider the user exit.

So, kindly assit me to solve this or do we have any standard setting by which i can control. this.

Thanks in advance
