Inventory Batch Reservations

(0) ShareShare

Posted on by 584

Hi.   We have an AX2012 R2 implementation with Auto reservation ON for Sales (in AR Parameters), and  with NO tick on "reserved ordered item" in Inventory & Warehouse parameters.   The basis for these settings was that we want to be able to auto reserve against physical available stock and not against stock being purchased from a vendor or being manufactured by us (on a production order).   Being a process manufacturer, we tightly control batch numbers.  They are automatically allocated on receipting inbound goods, or manually allocated in production orders.   All inbound goods requiring quarantine are attributed with the appropriate item model group that specifies quarantine management.

The issue we have is that whilst items on sales orders are not auto reserved against purchase orders, they do seem to be auto reserved against incomplete production orders.   As a result, when we RAF a production orders we will get as many quarantine orders as there are reservations.   For example ...

Production Order  .... 2000 each of a Finished Good ... batch number manually entered in inventory dimensions.

Sales order lines raised ...    10 ea, 20 ea, 200 ea. for the finished goods.  These appear to be auto reserved against the production order batch number.

RAF the production order ... AX created 4 quarantine orders  - QTY of 10, QTY of 20, QTY of 200, QTY of 1770. 

This is not the solution we expected!!  And you can imagine the mess we have when we have a produced item that spans many sales orders!   We have a manual workaround (very messy) ... but we need a fix asap.

Is it possible that by manually allocating batch numbers in production orders we are inadvertently opening the door for sales auto reservations?  

Is it possible that this is just the way AX2012 R2 works?

Help greatly appreciated!!

    In the planning parameters and your firming process for the production orders I presume your marking is set to Extended/Standard? This links the production order supply to the demand and splits it out, so if there is a quality issue it impacts on the related sales order. It is not the only element impacts on, but as a start point check the setting and do some tests with this set to None.
