Will MRP always select the default vendor when creating purchase orders?
Or will MRP recommend an alternate vendor (with a shorter lead time) if the preferred vendor’s lead time will not be quick enough for a Production Order/Sales Order.
But… MRP should be looking at lead times and making sure that you are purchasing your materials so they won’t be late.
Are you saying that MRP does this already, or that in theory it “Should” but does not at this time?
Assumign that it does this already, what lead times does it look at? Just the Mfg Lead time from the inventory planning tab on the stock item, or does it also take into consideration the lead time from the Vendors tab on the stock item?
Yes MRP already looks at the vendor lead times for the preferred vendor of the item warehouse detail.
For additional information on which values and lead times MRP uses, the MRP white paper covers this in the appendix:
