Quota arrangement for FG From DC to Plants

[raviram08]

My client's requirement is like this 

To distribute an MRP-run forecast for finished goods (FG) products from a distribution centre (DC) to three different plants in percentages.

Example Scenario:

• Distribution Center (DC): 1,000 units forecasted.
• Plant A: 50% allocation → 500 units
• Plant B: 30% allocation → 300 units
• Plant C: 20% allocation → 200 units

How do you map this in SAP using a Quota arrangement? Do we need to create vendor master data for plants? Please help in detail for set up.

Thanks
