Source Determination - Source list not considering while MRP run


I have maintained Quota arrangement for V1 and V2 vendors and in source list Vendor V3.

While MRP run in MD03, it is creating PR and doing source dtermination only for V1 and V2 vendors, It is not considering vendor V3.

While MRP run it is generating PR's for V1 and V2 and after that it is creating Planned order, but it should create another PR for vendor V3 from Source list.

Where i am missing.



I would suggest yout to test the source list in connection with another material for which no QA exists. Check whether MRP uses it.

If it is OK, try to maintain a similar QA for it and test what happens during MRP run. You can use sandbox environment.

QA should be considered during manula PurReq if you mark the "Source determination" check box in ME51N. But please be aware of this:

In connection with the quota arrangement, the splitting quota is only relevant to Materials Planning, not to Purchasing. In Materials Planning, requirements can be split up among various vendors. This is not possible in Purchasing.
