Prerequisites checks were fulfilled:
1) PIR is created with Vendor, Material, P.Org
2) Material has sourcing obligatory
3) Source list is created with P.Org and with valid dates: Vendor is marked as fixed.
Is there any other setting I maybe have overseen?
---
The field "fixed vendor" is not considered by MRP.
If you have several sources of supply and you always want
to have one of them selected by MRP, make sure that the field MRP is only
marked as 1 for this source of supply.
Tcode: ME01
Source List MRP field need to be marked as 1 - Record
