Determination Of Requirement Types

Dear Experts,

For "Determination Of Requirement Types Using Transaction", there are 6 Strategies (according to the HELP in SPRO) as below -

    1. First, an attempt is made to find a requirements type using the strategy group in the material master.
    2. If the strategy group has not been maintained, the system will determine it using the MRP group.
    3. If the MRP group has not been defined, the system uses the
material type instead of the MRP group when accessing the corresponding control tables.
    4. If no requirements type is found here, the system assumes a special rule and attempts to find a requirements type with the aid of the item category and the MRP type.
    5. If this is not possible, a last attempt is made to find a requirements type with the item category only.
    6. If the last attempt fails, the system declares the transaction as not relevant for the availability check or transfer of requirements.
    Would like to ask the followings -
    Q1) For the above Strategy 3, where can find the relevant configs. for the "Material Type" and the "Corresponding control tables" ?
    Q2) In OVB8 (Maintain Requirements For Transfer Of Requirements), if our company's config. is as below, what functions are being controlled by this config. ?

      Q3) In OVB5 (Maintain Requirements For Purchase And Assembly Orders), if our company's config. is as below, what functions are being controlled by this config. ?

      For your advice on the above questions.

      Many Thanks,

      KH Fong

      • Hi KH Fong,

        I have no idea why you are unable to search and find the suggested material. I tried all three searchs I showed and found multiple instances of content addressing your question. https://blogs.sap.com/?p=49249 comes right up and does a very good job of explaining how to use the functions you seek. If the blog does not show up with the direct link, then I would check with your IT department or service provider to find out why.

        Not much more either Veselina or I can do for you if your browser can't return information properly.

      • Dear Michael Appleby,

        Thanks for your advice on the above link. Actually it is difficult to search the required info. under this link as below -

        "........Else, In place of MRP Group, Material Type is used (IMG Guide > Production > MRP > Define MRP Groups for each Material Type)........"

        The above link (blog) should be mainly related to "Availability Check" / "ATP" so it cannot be searched by inputting keywords like "Requirement Type" / "Determination Of Requirement Type".

        Just one more question for the above Q1 -

        Even if it is completed to "Define MRP Groups for each Material Type", is it still required to maintain the "Strategy Group" for the "MRP Group" (as Strategy 2 for Determination Of Requirement Types) so as to fulfill the Strategy 3 for Determination Of Requirement Types ? If so, what is the purpose of this Strategy 3 as the Strategy 2 has already been fulfilled for the Determination Of Requirement Types ?

        Many Thanks,

        KH Fong

      • Hi Kwok,

        Sorry, but I have no idea. I got involved to help you search properly so that you could do the research yourself.

        Regards, Mike
