How to handle Multiple vendors MOQ in Navision

Dear All
I would like to know how Navision MRP handle multiple vendor with different MOQ.
EG: I have an item with the demand of 20 quantities. At the time of demand, this item is tagged to one vendor named ‘VEDOR1’. ‘VEDOR1’ has the MOQ of 200.this MOQ is updated to SKU card .then run a MRP and place the order for the quantity 200 for the ‘VENDOR1’. Then I added one more vendor named ‘VENDOR2’.’VENDOR2’ has the MOQ of 500. Where can I enter this MOQ for calculating MRP?
Thanking you,

I think In Navision MOQ is defined for item and not for vendor

You may need to customize.
