>> we make to stock and don’t use MRPThat capital equipment mfg. I mentioned earlier is mostly stock too.
- In their case one machine order MRP will generate approx 400 PO suggestions and 200 job suggestions.
- The majority of materials are NOT non-stock, a couple reasons:
---- Purchasing has trouble with the number of PO's when they tried non-stock
---- Mfg could not keep track of materials received directly to the jobs - parts in bins just so they can find them.

Same problem.
They're using timephase, custom reports & custom dashboards are used to identify demand/supply links... based on dates.
Purchasing is manually creating fewer PO's manually setting of dates & qtys.
They tested the system running non-stock (lean).
It was definitely easier to understand supply/demand but resulted in more transactions.
Finally considered non value adding, too much "busy work".
Switched to doing more manually, consolidating to fewer transactions.... in general.
However it is much more difficult to verify supply/demand.
Especially when more than one machine order is in WIP.
