Creation of PR with certain Doc type from MRP


My requirement is for creating Auto STO. PR's are getting through MRP and I want them to be converted to a specific PO Document Type.

I have created new PR Document type and assigned this to newly created MRP Group in Tcode OMDT and in PO Document type, I have made it to create only the specific PO Document Type. I have my Source List and info record in place and tagged MRP group to the material which I am using.

Now the problem Part :

When the MRP is run ( I am not expert at MRP), Most of the times PR document type is getting created what I am desired but source of supply not being pulled (I have only one source in the source list and MRP is been selected as 1)

And surprisingly if I change the validity period to a year before in source list and run MRP, then source list is determined properly but not document type.

I am confused how its happening.

Master Data, configuration from MM side looks fine to me. But not able to understand anything from MRP is creating an issue...Please help on this

    Did you check the valid from date of material in MRP 1 view.

    Coming to automatic p.o as you mentioned above,

    1) Activate "Automatic P.O" in material master "Purchasing" view.

    2) "Automatic purchase order" must be flagged in the control data for the purchasing data.

    3) Info record must be maintained for respective combination of material and vendor.


    In info record "general data" tab we have option of supply option "Availlabe from & available to".If you make use of this field, you do not have to maintain numerous source list entries.

    Hope this may help you to analyze your situation.

    Dear Sreekanth,

    While running the MRP system will check the material master data first i.e. Procurement type, MRP Type and lot size, Quota usage and MRP Group. here especially MRP Group is used for capturing the PR Document type

    if the procurement type is F/F30 /F40 then system will check the info record for this material combination who is vendor (if one or multiple)

    then system will check the Source list (Here source list should be valid as per the info record and will maintain the MRP Relevant ) here system will confirm that which vendor combination it has to generate the proposals

    lly if you maintain the Quota usage in the material master and Lot size then it will check the quota percentage for each vendor by considering the source list MRP Relevant vendors combination

    • As a general rule, just one question per thread, the content in the body should have a relation to the subject. If the question is answered, either by a user or by yourself, then the question should be closed. In case you found the answer yourself you should update the discussion with the solution.

      If you get new problems then you should open a new question. This is less confusing for the people, as they do not need to read countless replies until they understand the problem or know that the first 50% are not related to the current question at all.

      To your question: I am not aware of any customizing where a document type could control the appearance of a company code.

      This is usually to do with assignments plant to company or purchasing organization to company or plant.

      And I expect the same issue for any document type.
