Item with multiple replineshment ploicy

jangid2k3

I came across a semifinish item "A" which is purchase from two different sources.
Apart from purchase this item is also manufactured inhouse.
This semifinish item is further used in a Finished good Item "B" which is manufactured inhouse.
How should I define this semifinish item"A" & its replineshment policy.

I am using Nav 4.0

There can only be one default method, and therefore you define it as the most common.

The purchase order suggests the default vendor, if planning chose another, they make this decision, they also make the decision to make the product in house rather than purchase it, but this would have to be manually handled.
