Need negative quantity non-inventory items on Credit Memo

Question

Version: (2007A)
Description of requirements: (Please provide a detailed description)
Our customer issues many invoices with a negative quantity line item for a miscellaneous non-inventory item. These non-inventory items are used to reduce the amount of the invoice regarding miscellaneous credits to their customers.  These are not discounts.
When the customer wants to credit these invoices, they canu2019t create a Credit Memo based on the invoice because SAP wonu2019t allow this if there are line items with negative amounts.
When they create a credit memo not based on an invoice, they arenu2019t allowed to enter a negative quantity for a line item as they are for an Invoice. They are forced to create a credit memo not based on an invoice the inventory item line items and an invoice or Journal Entry for the negative quantity line item to debit back the miscellaneous line amount.
As an example:
Invoice line item one for inventory item: qty one, price 100,line total $100.00
Invoice line item two non-inventory item misc credit: quanity -1, price 10, total -$10.00
Invoice Total $90.00
In Order to provide the correct credit amount, they have to create a Credit Memo not based on an invoice for line item one, qty one, price 100 u2013 value -100 and an invoice for the non-inventory item for qty one, price 10 -  value 10.00.
This creates a net credit for the customer of 90.00
This looks ridiculous to their customers when they see these transactions on their statements, creates extra work for the users and there is no link between the three documents.
By using inventory items for these miscellaneous credits, they can assign a sales revenue of their choice. They have multiple sales accounts and the GL posting is determined by the item group for the item. By assigning the desired item group to these non-inventory items, they can control which sales account is updated on their marketing documents when using these non-inventory items.
If they were to use the Freight items, they would need a separate freight setup entry for combination of item group and miscellaneous credit. Because they have so many Item Groups and types of credits, they would need a great many separate Freight Charges to choose from.
All of the above pertains to all of our customers. This customer has a custom add-on and their marketing documents are all created from custom objects.  They hit a button on the custom sales contract screen and an invoice is created.  When they hit another button on the screen, the selected invoice is credited. They have legally binding contracts for fixed quantities to be shipped, so we decrease the quantity shipped when creating an invoice and decrease the quantity shipped when a credit memo is created. The contract is fulfilled when the exact quantity contracted for has been shipped. Because the credit memo fails, we canu2019t update the custom objectu2019s remaining to be shipped, rendering it inaccurate from that time forward. (reducing the quantity shipped is part of the Credit Memo creation process).Creating Credit Memos and Invoices from the interface fixes the inventory count, customer balance, etc., but we have no way of fixing the sales contractu2019s quantity shipped & remaining to be shipped or linking the contracts to the documents created from the interface.
Business needs: (Please describe the impact on your business, if the functionality is not realized)
Examples: (Please describe a typical example, how the functionality should work.)
Credit Memos should allow negative quantities and line total amounts for non-inventory items, the same way that A/R Invoices do, so that credit memos can be based on invoices that have negative quantity non-inventory line items.
Current Workaround: (Please describe the workarounds you are using at the moment)
Please see above
Proposed solution: (Please suggest how the new functionality should work)
Credit Memos should allow negative quantities and line total amounts for non-inventory items, the same way that A/R Invoices do.

Hi Sean......
System is behaving properly as per its logic. Infact it does same in all the previous or upcoming versions.
If you have Item Type GRPO for Non Inventory Item it does not create any accounting but you can see the same during AP invoice.
GRPO for such type is only optional. For further clarification you can discuss this with your CA what he suggests. But i suggest you to raise AP invoice also for getting Account effect. Just see doing this in test DB you get your answer......
