How to run master planning for a single item

Hello community members,

I have a requirement to run master planning for a single item using a specific master plan.

My scenario:

1. created a master plan called 30

2. Created a coverage group called 30 and attached it to Item T0200 which is a production item.

3. T0200 looks like this with, in red the on hand for each item within warehouse 11.

4. I ran master planning by filtering on coverage group 30

5. I was expecting to have a planned production order for T0200 and a planned purchase order for A0001, but no, here's what I'm getting instead.

Master planning is ignoring completely all the on hand on sub levels of my BOM item.

Is that a bug ? Is this scenario supported by master planning ? I'm just wondering.

If any feedback or any idea how I can do this, I'll appreciate your help.

Many thanks

Hy Sidik,

you are right, normaly I would also expect what you wrote. As the result is another there is anything we need to find out.

Are any site and warehouse data inside the used BOM for T0200 and D0002?

Are there any reservations on the stocked items?

Are there any other requirememts for the items we expect not to be purchased?

Did you delete all planned order before running master planning?

Take a look to the planned order where the requirements are coming from?

May be this is only the first step in the analyse of this behaviour, but we have to check multiple point.

Hope this helps

Hi Andreas,

Thanks for you help.

Are any site and warehouse data inside the used BOM for T0200 and D0002? Yes I have setup warehouse 11 for all Boms and components

Are there any reservations on the stocked items? No

Are there any other requirememts for the items we expect not to be purchased? No

Did you delete all planned order before running master planning? Yes

Take a look to the planned order where the requirements are coming from?

004737 and 004738 are coming from 004736

004740 - 004741 and 004742 are coming from 004739

I will add that this scenario can be played in a standard Contoso environment.

Hy Sidik,

I just did the setuo of T0200 (didn't fin that item) and sold one item.

I had the same behavour with the standard MasterPlan in USMF, had exact the same result like you.

So played around with item D0002 in a sales order, run mrp and master planing did NOT cretae a planned order as it is onhand available, thats correct.

After that a run mpr again aganst T0200 and the result was as we both expected.

I don't know exactly why, I know there is there some behaouviar regarding the BOM Levels an item is used. This will be regulary calculated as part of master planning. In case we filter mrp through item number or coverage group may this part was not run for item D0002. I assum thi scould be the point.

If you can reproduce still, please try this to

- delete als planned orders

- run BOM Level recalculation for all items

- run Mater planning

- share your result there

May be this is the root cause.

Still getting the same result

However if i run a full MRP without any filter, it works fine, but not if I run with a filter.

Hy,

for me too, Created also new master plan and coverage group, regardless which filter I take at master planing (no filter, Coverage group or Item number), the result is as we expect.

So I don't know where the difference is and I can*t reproduce the behaviour any more.

Finally I opened a MS case and seems to be by design
