MRP Inventory Acknowledgement Across Sites

Within our main company, we have several sites for different locations. Several of which hold inventory on parts but the part is setup for manufactured in our main site as it’s default site settings. When we run MRP, MRP does not seem to “see” the available inventory in the other sites as available to use inventory to fulfill orders from. We then have purchase suggestions for the raw materials that do not match expected amounts (over stated.)

I suspect we need to adjust some settings but not sure which.

The parts are setup as manufactured in site A and are manufactured there but then shipped to Site B for inventory overflow. The preference would be that MRP sees all the inventory and makes need to make job suggestion based on the open total balance not just what is needed to fulfill demand in site A where all the orders run through.

I think that’s going to be tough. At face value, you need a part in site A to be both source type “Manufactured” and source type “Transfer,” which is impossible, of course.

There is such a thing as pull quantity which works for subassemblies that you have stock of. It corresponds to “Auto Consume Stock” on the PartPlant record, FYI for MRP.

But I doubt it works in your case for several reasons.

  1. I think it only works in the same site
  2. You don’t need subassemblies pulled; you need the main assembly pulled, and that seems to be grayed out

So, I’m out of ideas. Maybe others have something.

I have no experience with shared warehouses (across sites). No use case here, and they scare me, honestly. Like I need more complexity! But perhaps that’s a possibility for you? Not even sure if it would do what you need.

Thank you for the thought.

Since everything is within “close proximity” meaning in the same city. I’m thinking we need to bring everything under one site and use multiple warehouses to resolve. Personally, I’m with you on shared warehouses. At the point that it’s shared, I would think that it makes sense to bring back into the main site.

I will look at our MRP settings and see if that is flagged. That might be able to help and can test in our testing environment.

Not exactly sure how you have it set up, but if you don’t have it this way already, you can have multiple sites defined on one part. Then one site would be type “manufactured” and the other “transfer”. Is this how you have it set up currently?

edit: I think I see what Jason was getting at with needing to have one site set to both manufactured and transfer.

That does sound closer to what you are describing in real life, but people have perfectly good reasons to split by site, and I’m not going to judge.
