For one particular part, MRP run is not generating the planned order. This material has a safety stock on it and when MRP runs, it would not create the PO. Instead, the available quantity is goin in negative.
Below is the config of the material:
MRP type : PD
Max stock level : 0
Procurement Type : F
Planned del time : 14 days
Service level : 0%
Safety stock : 10
strategy grp: 40
Availability check: 02
Please let me know if you have experienced similar issue and if there is any config to check.
There is nothing mentioned why it should execute planning for that material.
what is the current stock situation? are there any orders?

I will try this in testing. However, is this the manual step usually? Shouldn't the batch job create this file? Please let me know what batch job/program creates this file so I can check in the system.
I am not able to see the files for NETCH for other parts as well unless there is some other setting out there.. I will look and respond if this solution works. thanks so much for your help.
As Jurgen said, maintian the 'X' for NETCH in MD20 and you can verify the results whether the MRP is creating planned order or not in MD02/MD03 by selecting the check box 'display results before they are saved'. This is like a test run kind of thing.
Let me know if you need any more help.
Are you working in a retail system?
if you do, then check in WSL3 or WSL10 if your material is listed
because it is not planned despite of planning file entry when this listing is missing.
Sap explains the planning file in OSS Note 205681 - MRP: Planning file
entry for material requirements planning
That type is not allowed in our system and it's not retail. Moreover in the DBVM, i see only files for BOMs and not regular MRP material/parts.
here is the screenshot from QA env. QA env is also a recent prod copy so same behavior.
look at highlighted column. I was expecting to create planned order right there instead of negative. shown below MD21 and MD04 after running Md02.
below are the screenshots:this is a variant of mrp run which runs every 15 min. My only confusion is in the table DBVM, I don't see the NETCH files for these kind of materials ( only configurable BOMs or marketting material) however on ME21/in dbvm, I do see the file for this material that none of the
flags are checked ( not even NETCH). So I am unsure how these files are getting picked by batch when there is only one variant as below.
Below is ME03 screen
i would concentrate on material master first.
MRP1 -> MRP4 several importatnt fields like
Plant-sp.matl status , Planning time fence, Lot size, Scheduling values, Coverage profile , Discontin. ind,...just compare them with other 'correct' materials
also please run MM04 and try to find out all relevant changes
regarding MD21 i would try the following entries:
I've compared before opening this thread MRP1-MRP4 tabs and no difference there except lead time. And also I looked at any recent changes already and the recent change to this material was done to add the safety stock. So I compared the other material that has safety stock on it.
Also I've tried creating the files with NetCH and tried running md02, no changes.
Is there anything needs to be changed specifically after safety stock is added?
Thanks for your help,
MMBE shows 15 quantity which matches to MD04 available stock quantity. The problem is that the planned order nto getting created.
Although, I checked in MARC table for any record that has AHDIS = 1 and there are zero such records in the production system. And in QA I changed that value to 1 and ran MD02, and it deleted ALL planned orders so obviously it won't work.
Ok. The other check that comes to mind is the MRP group usage. By chance do you see this being used? A MRP group has its own set of parameters like planning horizon etc which has an impact on the PFE's again. Check the Pl.horizon of the MRP group, if used and ensure that it is not zero for instance, if used again. Recommendation is to have it similar to the plant level setting.
Aside, Have seen your reference to DBVM table above. Your MD04 screen shots show only Material/Plant and not Material/MRP area/Plant and hence DBVM is irrelevant in your case and for details you should be checking MDVM only.
just wanted to update you all that the issue was that there was a information record for this part with a planned delivery time = 999 which pushed all the planned orders way far in the future and created the issue. I wasnt aware MRP actually takes into consideration the lead time on the information record but not the material master data ( which in fact was correct in this instance). Is this standard ? or there is any setting for this in spro?
