Free goods by header net value not Quantity

Question

Regards
My client wants to make a sales promotions as the free goods SD. The difference is that free goods should not be given by the bought quantity of certain material, they should be given from the header net value of an order.
For example:
If a customer have an order with header net value of 100$ from only materials that has certain material pricin group, it should receive one free good.( All the materials in the order have the same material pricing group)
If a customer have an order with header net value of 200$ from only materials that has certain material pricin group, it should receive two free goods.
If there are ways to make this happen please let me know i would really appreciate it.
Thanks

Hi ronald,
The userexit option is very tough to do.
You are using a right userexit, but how are you coding it? Whats your design and flow?
The BDC are programmable recordings of a standard transaction. Hence you will be able to record the way in which you add a line item to sales order. Ths recording is automatically converted into lines of code by SAP. Then you insert your checks and balances between these lines of code to make it behave the way you want the sequence of transactions to work.
My thought was to make a recording of adding a new line item, in change sales order transaction(va02), with item category as Free of Charge(FOC). Then in the code, I wanted to check for material pricing group, if found correct, then would go finding the net value of sales document. If the value is above the limit, calculate the target quantity. Then follow the rest of the recording and add a new line with FOC as item category.
But this was a seperate transaction, which could be applied seperately and not to be done automatically in sales order. This was becuase say if you switch off the promotion tomorrow, then you will not have to worry abt removing the same functionality from sales order, you just need to de-activate the transaction.
Then there would be issues of doing hardcoding the net value limits, free good quantity in the user exit which is not at all recommended.
Hope this helps.
