We've a peculiar problem in the data that is getting CIF'd to APO. Following describes our data set up & then the problem we are having -
1. Our design is to have a Plant in the SAP system (locn type 1001) for each sub-contractor.
2. For each sub-con we also have a Vendor location (type 1011) maintained in SAP. Process is, when a Sales Order comes in a sub-con P Req is cut to the (sub-con) Vendor, who in turn gets the material from the "plant" & so on.
3. Now, when we are sending over Products to APO from ECC, some (few only) of the materials are getting extended to the sub-con vendor location there by causing Source of supply determination issues at the time of Order ATP (we use CTP process with Immediate Planning procedure)
Question - What causes few Products to get extended to the (subcon) Vendor location (in addition to his Plant)?? & how to fix this issue?
Any idea would be a big help
