Line-side chaos, mixed lots and shipping short against an ERP total are manufacturing warehouse problems — not an inventory-report issue.
Raw and packaging near the line, finished goods near the dock. They need locations and statuses even if finance sees one plant code. A total in ERP will not tell a picker which cage is on hold.
Manufacturers come because someone shipped the wrong lot or fed the line from a blocked bin. Those rules belong in warehouse jobs, not in a monthly quality slide.
The work order says what to make. The warehouse says what may be issued and where finished goods sit. Integration is the product. Renaming MES as WMS is not.
Walk the last short shipment or the last line stop for missing components. That walk is a better requirements document than a generic manufacturing module list.
Because ERP answered "how many". The line is asking "which one, from where, in what status".
No. Plants have bins and picks. Field crews have people and kit. Different objects. See the field operations case if that is your pain.
If mix-ups are expensive, yes. If one person can see the whole room, you can start lighter and still model locations.
