Hi
This problems occurs when you have manual discount condition types. Occassionally due to user errors more discounts will be entered and hence the order value/line item value becomes negative.
1. Define a new meaningful billing block like 'Negative value...'
2. In an appropriate userexit make the coding for the functionality as, while saving the document either in VA01 or VA02, the system should check the line item netvalue and if the value is found negative, then this specific billing block should be applied automatically at item level.
3. This will not allow the billing of this line item and only other items in the order will be billed. This will lead to invoice split. If you wish to avoid the invoice split, then the billing block should also be applied to the header billing block field (VBAK-FAKSK) also. This will block the entire document for billing, though the problem is not with all the line items.
