Could somebody explain me why Source of Supply is sometimes not filled with appropriate data ?
Here is my detailed case :
I have maintained a quota between 2 suppliers.
For supplier 1, I have a contract and no PIR.
For the supplier 2, I have only a PIR.
In the source list, I put the contract for supplier 1 and an entry for supplier 2. Both are relevant for MRP.
I am putting some independant requirements on the material (MD61) and running the MRP.
The PR are well splitted between the 2 sources, but in the PR associated to supplier 2, PIR is not indicated in Source of Supply and sometimes even Purchasing Organization is not found.
In the cases Purchasing Organization is found, but not the PIR, when I am converting the PR in PO, the PIR is found at PO creation.
I do not understand what is missing for the system to put all information directly in PR.
Thank you for your help !
