How to handle effect of sales price increase in already invoiced sales

Question

Our customer is dealing with parts made by metal.As metal prices are fluctuating, Customer need to raise prices of products.In some cases as the customer of customer take time in approval of prices increase, when our customer receives approval from his customer, he generates supplimentary bill, which is actually the price difference between old price and new price.
The issue is in this scenario,  material movement is not involved, so in SAP B1 if we take the same item which was supplied to customer earlier, then inventory will not allowed.
Request to suggest the correct process to record the accounting and tax effect in case of price difference case.

samir,
Direct Solution,
1.Reverse the ar invoice by ar credit memo.
2.Create a new delivery for customer with new price.
3.Raise ar invoice.
There is a work around as below,
1.Create a excisable item master as Item Code Supp.Inv.
2.Do goods receipt for item with qty as 1 and unit price
as total price difference(for all items) post good receipt to inventory account (to inventory account impact happens in case of delivery).
3.Do delivery for customer with qty as 1 and price difference
as unit price and with reqd. excise tax code.
4.Do Outgoing ex. invoice frm delivery
5.Raise ar invoice frm delivery.
Hope this solution will solve the problem.
