Item having 0 price is going through credit check

Hi,

We are facing following issue-

Our sales order is having multiple line items including a line item which creates network.

When we enter the line items with price in sales order, the sales order goes into credit check. Then we review & release the sales order from credit check.

Then we enter the item which creates network. This item is having 0 price (Not relevant for pricing). However, when we enter this line item, sales order is going again in credit check.

Ideally since this item is not relevant for pricing, SAP should not again put credit block.

Have anybody faced similar issue?

Appreciate your help in advance,

Shashi
