The business case for this is that we need to ensure we keep sufficient SMI stock to cover the pulls into our stock for a week.
I have written a function that manages this, but it does unapprove PO’s and kick off the approval routine, so I was hoping Purchasing Kanban is the answer.
Good news - it does work, you just need to be follow the instructions below. The key thing, is to assign the SM PO prior to any good been receipted.
The follow instructions from Epicor support solved it for me:
Production Management>Job Management>Setup>open Kanban Type,
Make sure there is a Kanban type with a Purchase Action type =Purchase - if there isn’t one you will need to create one,
Note the description of the Kanban type,
Save record
Production Management>Job Management>Setup>open Part,
Create a new part that is purchased and stock,
Save the record,
On the Plant>Warehouse tab select a bin location for the warehouse, Right click & add a new bin which is Supplier managed
Type in a minimum on hand quantity of 100 and a maximum on hand quantity of 200,
Select the Kanban type Purchase,
Type in a Kanban quantity of 5,
Save the record
Material Management>Purchase Management>General Operations>open Purchase Order Entry,
Create a new PO, list a supplier id,
Add a new line for the part created above for a quantity over the Minimum Qty set for the Kanban part for example 110 and list a unit price,
Save the record and note the PO number
Go back to part in part maintenance,
Under the Plant>Warehouse tab type in the PO and Line that was just created,
Save the record
Material Management>Shipping/Receiving>General Operations> open Receipt Entry
In the Summary Tab> type in the PO created above
type in a new Packing Slip, when prompted to add a new record, click yes
in the Summary Tab > Pending PO Lines Tab> double click in the line
go to Stock > Detail Tab> make sure the supplier qty and our qty are 110 & that it is receiving into the supplier managed bin
Save the record
**At this moment your OnHandQty is over the minimum Qty
Reduce that OnHandQty to below the Minimum Qty by using e.g. quantity transfer.
Go back to the PO in Purchase Order entry - refresh the screen - notice there is a release added to this PO with a quantity over the Minimum qty which would fulfill the minimum on hand quantity that was set up for the part in the part master file.
