WMS does not reserve according to FEFO

(0) ShareShare
ReportReport
Posted on by Islam Ayman Emam 45

It was noticed that when releasing the load to the Warehouse (i.e. create sales work and its replenishment), the system does not look at the location where the oldest batch(s) is found, instead looks at the nearest location containing on hand and allocates it as the picking location for the replenishment work. Although all the setup made for FEFO batch reservation is made and checked on numerous times.

P.S. Standard reservation hierarchy and reservation at the location level is done once I release to Warehouse.

I made all revisions on the setup made for FEFO reservation with no hope. I even tried to investigate if this problem persists on CU10 (our current version).

Can someone help? Did anybody encountered this issue before?

I can email the word document I made upon request.

    Thank you all for your help and sorry for replying all late. Solved the issue with the query and closed the case with them. I identified to my customers the problem and the workaround.

    Hi Islam,

    'FEFO Batch Reservation' is not supported as a strategy on the Location directive of type 'Replenishment'. If you want, you can vote up this Idea to have this functionality added:

    ideas.dynamics.com/.../ID0002633

    Thanks for the document. It is excellent. I think you would get the behaviour you want if you it the 'Edit query' button (on the Location Directive Action for your 'Pick' replenishment location directive) and set some sorting on one of the Batch date fields. If you already tried, I am interested to hear why the 'workaround' is not suitable, if you have time to share.

    Alternatively, you might be able to do away with Replenishments altogether (to get your inventory from the warehouse locations to the loading dock). You could use Sales order work with two Pick/Put pairs on the Work tempalte (and a different Work class for each pair). In this way, you could use the 'FEFO batch reservation' logic on the Sales order location directive to find your storing locations.

    read guy's comment and the white paper.

    With batch below you still have some options so I think the answer you got was misinformed.

    In the location directive on the location directive action -  mark the line as batch enabled, and then select strategy = FEFO batch reservation.

    When work is generated, Ax will determine which batches to pick and guide the work user to pick from those locations. The initial work will be created exactly based on FEFO, but the work user will also be able to when necessary to pick a different batch number (potentially from another location).

    You also have a setting on the mobile device menu item to Force the user to pick oldest batch from a location.

    Alternatively organize your locations in a way that you don't have batches with different expiration dates (there's a setting about mixing batches on the warehouse management parameters for this).

    Batch below sorting: Set up the location directive action query to sort based on expiration date. This way, it will suggest you the location with the oldest batch.

    For true FEFO this requires that you organize your locations correctly, and  do not allow mixed batches. .

    The down-side of using batch below is that some of the features like same batch reservation, batch attributes and customer sellable days do not apply when it comes to batch below.

    After opening up a case with Microsoft, they stated that the FEFO reservation is not supported on R3 CU10 (and don't know for the newer CUs). And she gave me @Fatih solution as a "workaround". So I set the Batch expiration date sorted in Ascending order. However, neither me or the Customer is settling for this workaround.

    Thanks my friends.

    Hi Fatih,

    Not at all, but on R3 CU 10 that does not happen

    RE: WMS does not reserve according to FEFO

    Hi,

    I have tried this in my 365 environment as below: 

    • Created 2 batches with same expiration date of their BatchID: 2018-02-28 and 2018-03-31.
    • Created inventory of 10 pieces for BatchID 03-31 in both in Location1 and Location2.
    • Created inventory of 10 pieces for BatchID 02-28 in Location3.

    When I set strategy to None, in location directive action, work is created against Location1.

    When it is set to "FEFO batch reservation" then, application selects Location3.

    Am I missing some setup of yours? It seems to be working fine in my environment. Do you have any sorting or additional criteria in your location directive actions query?
