[former_member185978]

Hi Experts,

When MRP runs @ 2:15 AM with the below Parameters , some Planned orders are created ( it should not ) instead of Sch Lines.

Please let me know what is the reason of creation of Pln orders?

MRP Parameters:

Scope of Planning --> Blank

Processing Key NETCH

Create Pur Req 2

Schedule Lines 2

Create MRP List 1

Planning Mode 1

Scheduling 1

Check box Display material List UnTick

Check box Parallel Processing Tick

User Ext key  : PRD

User exit parameters ICP PART

When I check MD16, there are 12 Pln Order created  For Eg :

Material Number     EXXXX

Order start           :12/09/2013

Order finish          :02/17/2014

Proc Type            :F

Pln Order number : 6065650

In Material Master for EXXXX MRP1.

Base Unit of Measure EA       each        MRP group            001

Purchasing Group     xxx                  ABC Indicator        E

Plant-sp.matl status                      Valid from

MRP Type             VB            Manual reorder point planning

Reorder Point        3                    Planning time fence  365

Planning cycle    Blank                MRP Controller       xxx

GR Processing Time   5   days             Planned Deliv. Time  70  days

Planning calendar Blank

SchedMargin key  Blank

User is manually converting this pln Order to Schedule lines whenever it get created.

I did check some of the blogs and it says , Planned ord will get created instead of Sch lines when the requirement lies outside the opening period.

FOr this above Material where can I see whether the requirement lies outside the opening Period?

Please let me know if you need any more information in this regard.

Will reward pts.

Hi Suraj,

Yes you are right! Yesterday before your reply I found this was the issue and I am in a process of analysis in Quality server ( by just giving blank ) and trying to confirm whether this is causing an issue.

In Quality I am trying to remove Sch Margin Key with blank values in Material Master and its not accepting anymore without values.

Anyhow thanks for your helpful answer. Will let you know once Corrected in production.

With Regards,

Hi Bala,

Try setting schedl margine key 000. Which ia standard SAP value. If you dont find any suh value then try to find possible value(f4) and select thebone with 0 opn prd ( first column towards right)

Hello

I wrote the following document about problems on source determination during the MRP:

http://scn.sap.com/docs/DOC-50026

You should take a look on the section "schedule lines are not generated".

Also, if you have a MRP group assigned to this material, you should take a look on the settings defined for the "creation indicator".

put the cursor into the Schedule Lines field in your MRP parameters and press F1

the F1 help will tell you what you have to check, and that this indicator is only used if it is not set in the other objects.

2-Go to ME01 for this code, check MRP related data.It must be 'Create Schedule Lines'
3-Check Mrp Control Parameter - SA Del Schedule Line must be 1 : Do not create Sch lines.
