How to stop MRP from generating PR

[former_member1180733]

Dear all,

I have one material with MRP setting as follows :-

MRP Type = VB

Reoder point = 1.0

Planning Cycle = blank

Lot size = EX

Max lot size = 0

Max stock level = 0

Now, although there is no reservation and the current stock is zero. The MRP batch job still generate the PR.

MRP parameter :-

Processing key NETCH

Create pur.req. 1

Schedule lines 3

Create MRP list 1

Planning mode 3

Scheduling 1

Question :-

1. What is the right setting for me to configurre.

2. Do I need to delete/reset planning file entries and how ?

Hi,

First check your MD61 is there any requirement pending.

Dear Rajendra,

There is no requirement types was found for that material in plant so and so.

Thanks.

what elements do you see when you execute MD04 for this material?

what is the quantity in your requisition?

[former_member1180733]

The qty created is one as per Reorder point.

Dear Husain,

If the reorder point level is 1 means,for that material you can use the MRP type as PD itself.

Is that a business requirement that strictly you have to use VB - Manual Reorder point planning?

Generally this MRP type is used for for the materials that are planned as per the normal consumption for the bulk materials or say

low cost items.It depends on the business req.once when the stock goes below the reorder point level,during the next MRP run

the system creates the procurement proposal for that material.

Normally this reorder level say you can fix it as 100 or 200 as per the past history or the average consumption.

If you want the system to create planned orders for the same ,check with the MRP control parameter value as 3 - create planned

orders during batch MRP run.

Dear Mangalraj.S,

Basically, the requirement is to keep very minimum stock if the material is too expensive. So, if there is a reservation generated from the work order, MRP will trigger the PR. Now, since the plan delivery date of the material is 6 months in advance, MRP still generate new PR although the old PR has converted to purchase order.

P/S :

> I appreciate the link that you have attached and consider point for it.

the delivery of the PO is beyond the planning horizon, hence it is not taken into consideration for MRP run.

[former_member1180733]

Dear Jurgen L.

Now, if I simulate in test client without any outstanding PO generated beyond planning horizon period. Why it still generate PR ?

Can you explain on planning horizon that can trigger PR during MRP ?

Thanks in advance

what did you see in MD04?

[former_member1180733]

Dear Mangalraj S.

Now, is it true that I must increase the stock equal or more that reorder point ? The problem is excpeted delivery date is in Jan 2010. The GR can only be performed next year.

Mangalraj.S,

1. The reorder point is 1 the current stock now is zero.

2. After MRP run the PR created with qty 1.

3. My expectation is no PR generated since there is no reservation/demand needed.

Thanks

Dear Husain,

Whether there is any reservation or demand for this particular material,but the sysem will create a PR for this material for 1

quantity as the current stock is zero.This is the standard SAP behaviour for reorder point level fixed materials during MRP run.

Come back with your further queries.

Dear Husain,

Unable to understand exactly your query, based on what i understand

You want MRP should not create ant PR for one particular material

then just make MRP type as ND

Check in MD61 what is your requirement. Based on that only it will trigger the pr
