Mass deletion of previous demand/requirements

[Former Member]

Hi,

We have migrated from Discrete to repetitive.

But there were some dependent requirements and Production orders open.

Every time i run mrp i get planned orders for these requirements.

I have checked the demand in MD62 but i could not find any demand in those dates.

How to delete these requirements in mass or at table level.

I have been through some links and found that it can be deleted at table level using MDPB table if yes can you tell me how to use it.

Thanx in advance.

Try running MRP by setting up a background job during off-peak hours with the following parameters...

Processing key            NEUPL   Regenerative planning
Create purchase req.      2       Purchase requisitions in opening period
Schedule lines            3       Schedule lines
Create MRP list           1       MRP list
Planning mode             3       Delete and recreate planning data

Scheduling                2       Lead time scheduling and capacity planni

Hello,

Try with planning mode delete & re-create.

or else check MD74 - deletes only the PIR

I'm surprised you use NEUPL and planning mode 3 for daily MRP run. Either you do not have many materials or your server hardware specs are really high.

This variant is used for mrp run which is carried out once in a month.

Hello,

Use Tcodes- MD74 & MD75 to delete OLD PIR's in system which are not assigned to any sales requirement.

So run MD74 & MD75 then close/delete any open production order before running new MRP.
