Restrict Material type creation using MM01

[joseph_chen5]

Hi experts,

We want to restrict some user's usage when access MM01 with limited material type. I have done below steps:

1. We hae a material type ZNBW

2. Create an authorization group ZNBW in SE54.

3. In OMS2, Assign Authorization group ZNBW to material type ZNBW ( I use the same name of material type and authorization

group).

4. Create a role which contain MM01

5. In authorizaiton object M_MATE_MAR, M_MATE_MAT, and M_MATE_VKO, assign only activity 01 and Authorization group

ZNBW.

6. Assign this role to testing user.

After above actions, the testing user is still able to create new materials of other material types, can anyone tell me what's wrong with my action? How can I do the MM01 restriction?

Hi,

If there is no auth group on the other material types then the user will be able to create them. If the auth group is blank then there is no effective check performed.

You need to put auth groups on all the types that you want any kind of restricted access to and provide the corresponding sets of auths to the relevant users.

Hello Alex,

Thanks for your response. So you mean if I have 10 material types I need to assign each of them to an authorization group. After that I just can restrict some material types into users. if there is one material type which doesn't assign to an authorization group, this restriction will not effective, is that right?

Hi Joseph,

Your understanding is correct.

The Authorisation Group concept usually works on the principle that if there is no group against that item, the check for that object is not effective.

As Shekar pointed out, you don't have to create the auth group in SE54 as the field in OMS2 will allow any 4 chars. I prefer to create the groups but nothing forces you to.

Hello Shekar and Alex,

Thank you for your information.

Cna you help to check my steps?

In SE54, I don't need to create authorization group for my purpose, right?

And in OMS2, I need to assign an aurhotirzation group for each material type and so that I can restrict the MM01 with material

types in authoirzation object M_MATE_MAR, MATEMAT, and M_MATE_WGR. Is that right?

Hi Joseph,

All you need to do for material type restriction is

1. Assign auth group in OMS2

2. Restrict M_MATE_MAR appropriately

3. Transport config & role changes

M_MATE_MAT & M_MATE_WRG are for material groups which is a different way of classification.

Thats a very interesting comment. Infact you pinned it perfect

there is a subtle difference in M_MATE_MAR and M_MATE_MAT,as you rightly pointed out

If we consider FInished goods as a Group of products that are "ready for sale" and if this is considered as group FGRP

you could also seggregation on materials that are finished products but have different attributes (it could be size, pattern or any other differences) - these are defined as material types. But these material types are still a sub set of the Finsihed Goods group

you can also have material groups created based on similar material attributes (all products that have a similar design pattern can be one material group, and this material group can be applicable to different group of products, this means a material group can belong to not only FGRP but also to FXXX)

Now, M_MATE_MAR will restrict on the material type you created (ZNBW)

As Alex mentions M_MATE_MAT would restrict on the product group under which you have the material type and M_MATE_WRG will restrict on the material group in which you prefer to have this material type

wow......took some effort to sort it right in my head

Hello all,

I am so appreciate for your advice. After assign authorization group to all material types I can restrict MM01 authorization with limited material types as our purpose. Thank you very much.

step 2 is not needed, the authorization group defined in the material atrributes via OMS2 has no relation with the authorizations group created from SE54

M_MATE_MAT and M_MATE_MAR are fine, M_MATE_VKO does not have a restriction on the material type

> 6. Assign this role to testing user.

check all other roles in the test user

Hi Sir,

Pl. note i have tried all the above remedies to resolve my issue for the Material Type restriction but still facing issue.

Requirement : There are 5 material types and i want to allow the user for one material type only.

When user enter's the transaction mm01 then he should only able to create for the material type to which he is authorized ( the material type "XXXX" ) only. and not for the rest 4 material types.

But using the above steps i am unable to restrict.
