Automatic purchase proposal creation with Source of Supply Priority rule setups.

Dear SAP Community members,

I have been testing the function of planning with “Source of supply priority rule” in ByDesign, but I believe the result of the function is not aligned with the help document “Source Determination in Planning.” Please guide me though this.

The below is the case that we have been testing.

1. The planning data of the material is set with “Supply of Source Priority Rule” for all of the sites.

2. The list price is maintained for this material (external procurement). When I check the source of supply of the material, I can see the list price.

3. There is not enough inventory for a sales order.

4. When I run the planning in Product Planning details, ByDesign creates a stock transfer proposal from other site where there is no inventory of this material.

For #4, My expectation is that ByDesign should create purchase proposal because there is no available inventory in other sites (internal procurement).

Please tell me if you have any advice on what I might be missing, or this is actually the expected result.

Sincerely,

Yamato Tomaru
