On-hand performance issue - Cleaning jobs impact

(0) ShareShare
ReportReport
Posted on by

Dear all, 

Since our go-live last summer, we have seen the performance of the Inventory > Inquiries > On-hand getting worse and worse. Not only the display of the form but also the export to Excel (which is needed on a regular basis by our Sales reps) are taking sometimes hours to display/run.

FYI : we are using the Warehouse Management module and AX 2012 R3 (CU10). 

After searching around, we have found a couple of blogs suggesting to run several Cleaning jobs to reduce the size of the InventSum and WHSInventReserve tables; namelly :

  • On-hand entries aggregation by financial dimensions
  • Warehouse management on-hand entries cleanup). 

Our main concern with these jobs is to understand the full impact they have on other aspects of AX.

The only detailed explanation we  found on the second job (WHM on-hand) is  : 

A possible user impact is that if we have deleted all records for e.g. the license plate level, then the functionality where we can see that we at some point had on-hand at a license plate does not work as expected, simply because we have no on-hand entries to represent that.

This is the functionality where Quantity <> 0 is checked in the Dimension Display settings when viewing on-hand.

We didn't find much on the other job. 

What we are looking at, appart from theoretical description is a first hand experience on the impact of those jobs. Doesn't anyone already ran them ? With what exact impact (negative or positive). 

thanks !

    Hi David,

    There is a good write up for the first one you mention here:

    [View:https://blogs.msdn.microsoft.com/axsupport/2016/05/11/key-clean-up-features-for-inventsum-and-inventdim-tables/:750:50]

    For me, the On-hand aggregation job removes records that you will never need. i.e. it should have only positive benefits. However, if you use Standard Cost, you will want to install the updated hotfix KB2951209 (included in CU12), else you may get an error when updating standard costs after running the job.

    I have one customer running this job weekly, and plan to use it routinely on new implementations. The reason we used the job in the first place was for two reasons.

    • We needed to delete some License plates, but were unable to, even though the LPs contained no stock.
    • The On-hand inquiry contained an ever increasing number of records with zero quantities

    It was suggested as a solution for both problems by MS support.

    Thanks Guy,

    We'll have a look at the Standard Cost bit as we are indeed using it in some of our companies.

    We've however been running those 2 cleaning jobs on our TEST environment are don't see that much of a improvement in the On-Hand screen...

    On the same topic : do you know if the "On-hand entries cleanup" would aso have a positive impact on the on-hand ?

    Hi David,

    Sorry, I've never needed to use that clean up job.
