Change Item Quantity in the Billing Document ( Proforma Invoice )

Question

Hi,
There is a requirement from the client to change the quantity at item level in the billing document ( Order based Proforma Invoice ) after it is saved.
As SAP does not allow to change in the VF02 transaction, Please let me how to change quantity at the item level of the billing document.
Please let us know if we need to use any user exit or any other system modification.
Regards

Hi Venkat Rama Reddy
First of all Welcome to SDN forum
Now coming to your query , your requirement cannot be fulfilled  as standard SAP doesn't .Because ,First of all at billing level you cant change the item quantity , then in VF02 it is not possible.But if your clients requirement is to change the item quantity in VF02 , then first of all do VF11->VL09->VL02N and here you can change the picking quantity and then do the billing ,as once if you change the picking quantity then at billing item  level also the item quantity will change
Check with the following user-exit  USEREXIT_SAVE_DOCUMENT_PREPARE. Here with the help of the Technical consultant include the requirement that after saving the billing document we can change the item quantity
But it is not suggestible to change the item quantity at billing level . As once you save the billing document , an accounting document will be getting created.
