Re: warehouse facility set-ups

In our 1998 implementation of 405 CD we setup a warehouse where finished products to ship customers get final assembly.

We had to do a modification (program MRP80W)
to alter the planning file defaults so that material to be consumed for end item type-1 will come out of the shipping warehouse 21
while other parts of type 2 get their materials out of WIP warehouse 22
This because of system parameters expecting one warehouse in a facility to have the raw materials that go into manufactured parts.

This has worked fine for us.
We run MRP80W before MRP500 MRP600

Customer Orders call for materials to be shipped from the shipping warehouse.
Purchase Orders call for raw materials to be delivered where needed.
Production Orders end up in the right place.
No problems with warehouse setup.

BPCS 6.1 heavily modified (but not in manufacturing).

In our infinite 1998 wisdom, we set up a warehouse that is both a
manufacturing area and a shipping warehouse. It points to the same
facility.

Someone mentioned that it is an incorrect setup.

We have not been using planning data in the warehouse to our full
advantage but are planning to do so. Our fear is that we will have
problems when we start using the planning data.

Has anyone used a manufacturing warehouse and shipping warehouse for the
same facility? If so, has it created issues? Please expound.

Thanks.
