MRP run for unchanged material.

[Former Member]

Dear Experts

I have an issue like this.

Since 4 years material (X) not came into MRP run. But suddenly that material (X) came into MRP Run on 04.10.2015.

Material Master:

Material Type: ROH

MRP Type: V1

Reorder Point: 1

Lot Size : HB

Maximum Stock Level : 1

MRP Controller: XYZ

Procurement Type : F

Availability check : 01

Material (X) lastly changed on 10.12.2011

Material (X) lastly Procured on 02.01.2010

Material (X) lastly issued on 08.12.2010

Since 08.12.2010 Material stock is Zero.

No Material Master changed.

No MRP Controller changed.

No Variant changed since 6 years.

Material is not assigned to any BOM.

We are running MRP on every Sunday since many years.

Even though stock is "Zero" since 08.12.2010, Why suddenly Purchase Requisition is generated on 04.10.2015 MRP Run.

Note: Not only the X material many material came into MRP Run on 04.10.2015.

Please kindly help

Hi Mohammad,

Check for any other background job that has run during that day for consistency check of planning files ? This material should be a part of MRP run long back as per the Material master settings. It seems planning file consistency check is carried out recently, either manually or by a background job.

Hello

A other option is that the planning file was not marked for this material and now you ran MRP with key NEUPL, so all the materials were planned, including this one.

Hi Caetano

variant is not changed and in that variant since many years we are using NETCH and we never changed to NEUPL.

hi Mohammad,

in DBVM table can you please check at what date and time planning file entry been changed.

like DBVM-USTMP = 20,120,109,145,517 means date = 2012/01/09 time 14:55:17

Hi Solomon

I am unable to get any data in DBVM table.

I am passing the Material number in that table.

Hi Mohammad,

One option is that the material was not in your planning file entry (then was not included in your MRP run) and somehow it was recently added.

You can check the planning file in MD21

Hi Mariano

Thanks for the response.

As per my knowledge If any changes happened in Material Master then an entry will appear in MD21.

But i didn't changed any Material Master since 10.12.2011.

Hi Mohammad,

That is partially true.

If the material is not in your planning file entry, even if you change something in the material or consume the inventory, the planning file entry is not updated.

This is the reason why you should have a background job of MDAB in order to generate your planning file entry.

Now once the material is part of your planning file entry.. then everytime that there is a modification, this modification updates the planning file entry in order to run the MRP.

You will find lot of thread that explain this in the SCN community.
