Planning Network MRP - Share Purchased Parts

Hello,

 

We have two sites, Site A and Site B set up in a planning network. Both sites A and B can purchase Part 1 from an external supplier. The Site A internal supplier is setup as a multi-site planned supplier for Part 1 on the internal Supplier for Purchase Part on Site B. If Site B has demand for Part 1 and has no on-hand quantity, the planning network MRP is creating a purchase requisition from the external supplier even though we have sufficient on-hand quantity at Site A to fulfil the demand at Site B.


Is this standard behavior? Is there a way to change this to have the planning network MRP recognize the available stock in Site A and create an internal distribution order instead of an external purchase requisition? The external supplier is the primary supplier on both sites and should stay that way, but if stock is available at the other site, we’d like to use that rather than buying more.

 

Thanks for your help,

Dylan​

Hi ​@Henk Visscher, our sites are near enough to each other that we just made one site the primary buying site and the other is supplied from that primary site when needed. It’s not an ideal solution, but something that we were able to make work. I would have expected that by default planning network MRP would consider supply at other sites within the planning network before looking to purchase from an external vendor, but that doesn’t appear to be the case.
