MRP run for unchanged material.

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,

    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

    Kind Regards,

    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.
