Unfinished scheduling processes/Item process duration statuses

(0) Share

Report

Posted on by Ree-G

Hi all,

I have been doing a lot of investigations on ways in which to improve the processing time of Master Scheduling batch, including looking at the "Unfinished scheduling processes" and turning on track "Process task duration". I have turned this on and can navigate around, however the issue I am having is finding support with what the data actually means, specifically the "Status" columns.

EDIT - Thanks to Colby Gallagher for pointing out the screenshots aren't showing.

For "Unfinished scheduling processes" the available statuses are
Installisation
Recalculating Item Levels
Deleting and inserting data
Coverage planning
Futures messages
Action message
Updating Dynamic Master Plan
Auto Firming
Statistics
Ending

For "Item process duration" the available statuses are
Deleting and inserting data
Coverage planning
Futures messages
Action message

Can anyone shed any light on what these statuses actually mean? Or point me in the direction of where I can find this information?

Thanks in advance.

Awwwww.. Getting Master Planning faster..

The closest thing to getting all these defined is a lecture on the learning portal where a performance tuning Master Planning session was given for the 2016 conference I believe. Just search for master planning performance. The standard best practices to get it down to 3 and a half hours are documented on the premier support blog.

I also wrote a blog post with some observations from tuning Master Planning. It doesn't have to be 3 and a half hours for a major enterprise organization. I've taken 2 very large multinational implementations to under an hour. And I could have gotten it down to under 10 minutes but the implementations stopped me from further tuning after I got it down to a point where they were satisfied.

Search Master Planning Performance on the learning portal. That will give you the closest thing to the definitions. It will also give you a chance to do all the standard things like planning with future messages and action messages, being well indexed, cleaning master planning tables, Then, after you cover the basics focus hard on "deleting and inserting data" and "coverage planning". Deleting and inserting data covers which items will get planned. Coverage planning is where the actual planning takes place.

These are all common terms used in master planning in Dynamics Ax and their meaning seems to be self evident.

This short video outlines the general concepts https://www.youtube.com/watch?v=E2n1a3OITIE

You can see the same presentation in slide/pdf format here https://www.axug.com/HigherLogic/System/DownloadDocumentFile.ashx?DocumentFileKey=69a2cec2-006b-a8dc-b6a5-c75a76eb91d2

for actions and futures see https://community.dynamics.com/ax/b/timsaxblog/archive/2016/11/02/master-planning-messages-in-dynamics-ax-2012

also see this two part series https://www.ebecs.com/blog/master-planning-unplugged-volume-2-coverage-and-item-planning

For performance follow the best practise guidelines on the support blog/technet for hardware configuration, database configuration, Ax configuration. run sql maintenance tasks especially to update statistics.

Set your coverage fences only as far ahead as you need.

Check Negative days parameter on the coverage group and the value should not be less than the lead time of the items assigned to the coverage group

Check Positive days parameter on the coverage group - should not be 0 or empty (else inventory will not be taken into account for planning and unneccessary new planned orders will be created.)

In all the companies master planning is executed, set the Master planning parameters – ‘Use of cache’ to Maximum

Use helpers for master planning

Request , helper threads when running master planning, set the Scheduling helpers - Number of helpers parameter in the Master scheduling dialog to a value greater than zero.

TechNet: http://technet.microsoft.com/en-us/library/gg242496.aspx

The number of threads requested by planning should not be greater than the sum of available batch threads on all batch servers in the selected batch group that runs master planning.

Either set the number of master planning helpers to be lower than the sum of available batch threads, on all batch servers in the selected batch group to run master planning, or increase the number of threads on selected batch servers

check the latest hot fixes related to lead times applied to your environment.

One example is KB article 2938941: https://mbs2.microsoft.com/Knowledgebase/kbdisplay.aspx?WTNTZSMNWUKNTMMYZWLSWZQTLLRPPXLZNRORZMMMSSMTMNPU

Also check whether you need this hotfix - LCS
https://fix.lcs.dynamics.com/Issue/Resolved?kb=3159477

Use multiple AOs for mrp and preferably run out of hours.

If performance is still an issue, then disable scheduling optimization i,e. set uncheck Scheduling optimization timeout
