Manufacturing part number not recognized in MARA

scenario:

we want to use a MPN for our material.

we have only ONE MPN per material and according to all the documentations I read, including Help.sap.com, if there is only one MPN there is no need to create a MPN type HERS but we can add it directly in the MPN in the material master of the internal number.

we added the MPN to the material master together with the vendor and the MPN profile and that worked but when we tried to create an info record for the MPN, we got a message that the material does not exist.

same for sourcing: when we tried to enter the MPN in the sourcing EMATN, we got a message that the material does not exist in table MARA.

settings in OMT0 are done, OMPN is done, AMPL is not used as we have only one MPN per material.

what am I missing?

If you use material type HERS, for which number do you then create the info record? for the HERS material number or for the MPN number?

I am not familiar with this process, but I really believe that you create info records with HERS material number.

And if you have just 1 MPN number then it means you create the info record with the normal material number, since this has the MPN number in the purchasing view, exactly like HERS materials have the MPN number in the purchasing view.

the documentation states that if there is a 1 to 1 relationship between the MPN number and SAP number, there is no need to create a material master for the MPN number: it should be sufficient to enter the MPN in the Purchasing view of the internal material master number.

info record must be created for both numbers and sourcing starts with SAP original internal number and the MPN is inserted in the overview EMATN field as stated here

if you have a material number 1234 and jut one MPN number MPN1 then you just enter MPN1 in the material master of material 1234

if you have multiple MPN numbers then you create HERS materials 2345 with MPN2, 2346 with MPN3 , 2347 with MPN4 , don't you?

When you create an info record, do you then create the info record for 2345 or for MPN2?

If you create the info record in this case for 2345 then you create the info record for 1234 if you have just a single MPN number. Logic or not?

not really: the internal number remains the same for all the manufacturer numbers: if you have SAP internal material 1234, the multiple MPN numbers are for the material 1234.

so you create material MPN1 HERS where the internal material will be 1234, same for MPN2 HERS always for material 1234 etc.

at the end, in transaction MP01 (approved MP list) you enter internal number 1234 and MPN materials MPN1, MPN2 etc etc.

the info record must be created for 1234, MPN1, MPN2 etc etc. In sourcing list you enter 1234 but in the overview screen you also enter MPN, MPN etc materials.

MARA should recognize these materials and if there is only 1 MPN for material 1234, SAP should recognize it from the MPN entered in MPN in PURCHASING view in material master 1234.

you cannot create several times the same material number, any HERS material has its own material number, you get it automatically if you have internal numbers whenever you do MM01.

see here a book excerpt: https://books.google.de/books?id=WoxeBAAAQBAJ&pg=PA654&lpg=PA654&dq=material+type+HERS+MPN&source=bl&ots=n2CLgJ0a9N&sig=7JyBEYxJiJ0LErBmzStCaPa-Pl4&hl=de&sa=X&ved=0ahUKEwjo7sXF9MLTAhXK0RoKHQcOCssQ6AEITTAE#v=onepage&q=material%20type%20HERS%20MPN&f=false

cannot see the excerpt, it shows only the link to the book.

but we are saying the same thing, just in a different way.

the material HERS is the manufacturer part number which contains info about the link to the internal SAP number.

but it is not a SAP number that contains a manufacturer number.....

so if I created 3 HERS MNP materials that have the same SAP internal number, I can enter them in the approved parts.

my question remains tho: if I only have one MPN, I do not need to create a HERS material for it: I can insert it directly into the material master of the internal SAP number and that should be sufficient for me to be able to create a PIR and sourcing with MPN.

see also this short but good document about the creation of MPN

my question remains as well, do you create info records with the HERS material numbers or with the MPN numbers in cases where you use HERS?

I suspect your APN Profile does not allow you to order with the MPN number. Check the profile, unfortunately if you have already created the profile it'll be hard to determine this. Try and create a new profile and see what options are available. You will notice, there's checkmark to allow you to create info records for HERS and your own material
