Scenario on Purchasing Process - Freight Charges to Different Vendor

Question

Hi Experts,
We have a business scenario here that we want to implement on the MM - Purchasing Process.
My Client's industry is on Selling Mixed Concrete. Every time they make Contract with Scheduling Agreements, for Raw Materials like Cement 20MM or DUST, on each available Plant from a partner company on a different location. Some of the Location are not inside the country as well.
When we do Scheduling Agreement, we do a blank quantity for example, 30,000 for 20MM on Plant A and 10,000 for 20MM on Plant B. During the creation of Schedule Lines, we key in differect schedules of delivery (incl PGR). Then by the end of the Period, we create a Vendor Invoice.
However on some delivery item, we have a scenario where from a specific Vendor A, we have a Vendor B that delivers our Materials to our Plant (Transporter Vendor). So we have to create another Invoice for them. We have to have 1 Invoice for the Supplier and 1 Invoice for the Transporter Vendor.
I understand that SAP can do 2 Vendor assignment on PO, 1 for Material Goods and 1 for Freight Charge. The Amount will sum up per Ordered Item and during PGI, the Material Cost will be based on this amount. I'm okay with the first statement but the summed amount is not okay with some scenarios.
The problem with some scenarios is that we should not base the Freight Charge on the schedule quantity. We agreed that the Quantity to be considered for Freight Charge is based on their Shipment Tonnage Agreement (which is weighed on the Vendor 2's side). Then for the Schedule Line Qty, we have to take the Average Weight from our side and from their side, and that should be the Schedule Line Qty. The Amount to be posted in PGR line item should be the amount from the Schedule Line Qty and the Freight Charge based on the Shipment Tonnage Agreement and the Material Cost will be valuated with the sum of these values. At the end of the Month, we create an Invoice for the 2 Vendors at the same time: one with Freight Charge the other on is the Stock Amount.
So for this requirement, is there a way we can add another Quantity, based on the Shipment Tonnage Agreement to calculate the Freight Charge inside, And the Transporter Vendor, in the Schedule Line Conditions to be included in the PGR?
Please suggest me configurations to do this also.
Thanks a lot for your suggestions.

Hi Cruz,
If your requirement is to bill on the monthly average basis for the freight vendor, you can create new condition type for freight based on quantity. Use the calculation type 'M' - Quantity monthly price, in conjunction with the scales and use the scale basis 'C' if the freight cost is fixed based on your shipment agreement.
If your agreement is based on no.of shipments use the scale basis 'S' - no. of shipping units.
Even if these two are not suiting use the scal basis 'G' - formula and define the calculation based on your requirement.
Once this is configured for the condition type. Then maintain the conditiona values accordingly.
Hope this is helpful.
