Material group in Material master

Dear All Warm greetings
How to configure display of materials through material group? For end users
Example when my user wants to view any material, system should only show the materials which he should as per material group
Example while create Purchase requisition/Purchase order & display of material from MM04
I tried by using parameter id in user profile, own data
WGR & WM1 but doesnu2019t work
Pleas advice me how can i process, Help he out with some solutions.

I am a little unclear of your requirements.
SET/GET parameters (from 'user profile own data') generally only work when the field is displayed on a selection screen for a program. The parameter will then automatically populate the field on the selection screen.
As it happens, the two parms WGR and WM1 you mentioned are not used by any programs that I can see.
MM04 does not contain material group, assigning a set/get parm to your userid wouldn't change much anyway.
If you are talking about making it easier for your users to select a material, based on materials assigned to a material group, then you could try the F4 help on Material 'L - Material by Material group' Here, you could enter the MatGrp and then have displayed a list of the materials that are assigned to that group. From this list the user could select the appropriate material.
If you are talking about pre-populating the Material Group field in ME51 (probably other screens as well), try using parameter MKL in your user parameters. You should log off/log on after changing a SET/GET parameter to see the effect.
If you are talking about PREVENTING a user from displaying materials outside of a particular MatGrp, then you should consult with your authorization team to see if they can provide a solution.

Restrict material groups at PR/PO creation for items w/o material master

Dear SAP experts
I have one question related to restricting material groups which are possible for selection during purchase requisition or purchase order creation.
The material group is created and several material master records are linked to it. Now the requirement is that when users are creating either purchase requisitions or purchase orders it shouldn't be possible to select that specific material group>
But this should be valid only if PR or PO are being created for items without material master record. If PR/PO is created for item with material master record then the restriction should not take place.
What would be the nicest solution to achieve that?
Thank you all in advance for your help.

Miha

Hello Prakash
Thank you very much for your answer. i think it is a very good starting point.
However I am not too familiar with authorization group configuration of material groups.
Right now in our system (transaction OMSF) field authorization group is empty for all existing material groups.
Does this mean that for the material group that I want to have restricted I need to have two entries: one with Authorization group ZOK and another with ZNOTOK (or whatever the naming would be)?
Furthermore I would like to ask you where is then the link between authorization group and user exit?
And thirdly: do you perhaps have some more details which user exit(s) are relevant for our topic?
So far thank you very much and I hope that you can provide me also with additional info.

How to create material group in material master.

hi guru's
can anybody explain me how to create a new material group in material master.
i wantto add a material group while creating material master MM01..
thanks
sap-mm

Hi,
In this step you create material groups.
You also have the option of using the same transaction to carry out the following activities:
Creating superior hierarchy levels
Assigning the superior hierarchy levels to a material group hierarchy
Assigning the base material group to the material group hierarchy
Assigning characteristics profiles below material group level
Requirements
Your R/3 System is configured as an SAP Retail System.
Activities
1. Create superior hierarchy levels
   You create hierarchy levels using transaction WG01 (creating
   material groups) via menu options MG environment --> Hierarchy
   level --> Create
2. Assign the superior hierarchy levels to a material group hierarchy
   You assign hierarchy levels to a hierarchy using transaction WG01
   (creating material groups) via menu options MG environment -->
   Hierarchy level --> Maint. MG hierarchy
3. Create material groups (base material groups) and then maintain the
   pre-defined materials (reference material/material group material)
4. Assign the base material group to the material group hierarchy
   You assign the material group to the hierarchy using transaction
   WG01 (creating material groups)
5. Assign characteristics profiles below material group level
   You assign characteristics profiles using transaction WG01
   (creating material groups)
Further notes
When creating material groups and then maintaining the pre-defined materials (reference material/material group material) you should be aware of the following.
As these materials can be created automatically using a minimum of data, you should follow this procedure with a check and possibly further maintenance, especially of plant-specific data. The material group reference material should be defined in as much detail as possible so as to keep the workload to a minimum when you have to create more materials for this material group.
All hierarchy allocations involving a material group (base material group) and a higher or lower hierarchy level can be carried out on the initial screen (there is no need to switch to the detail screen). All further hierarchy allocations can be defined top-down when you maintain material group hierarchies.
Only the material groups are transported automatically!

" Item Category Group" in the material master?

Hi,
I'm going to use inbound delivery for purchase order, so I'm going to do it as follows:
1) Create a new "item category group Y001"
2) Create a new "item category Y001 (copy from ELN then change the movement type to 101, and set it relevant to putaway)",
3) Replace the item category group in the material master with Y001
4) Determine the item category via transaction 0184 as the following ways:
     "Delivery Type" EL    +
     "Item Category Group From Material Master" Y001    +
     "Item Usage" V     +
     'Item Category Of The Higher-Level Item"
     ==> "Determine New Delivery Item Category" Y001
My question is, If I change the item category group in the material master, is there any effect to SD part?
Thanks.

hi
General item category group
Materials grouping that helps the system to determine item categories during sales document processing.
*If a group is configured specific to distribution channel, it has priority if the corresponding activity is distribution channel-dependent
Item category group from material master
A grouping of materials that the system uses to determine item categories during the processing of sales documents.
the difference between the two lies in the specificity to the distribution channel

Purchase group in Purchase order from creator not from Material Master

Hi All,
Can you please help me with the next one?
Points rewarded.
In the materialmaster is purchase group 44B entered but
The default purchase group of the buyer is 55C. Is it possible
that the value 55C is automaticaly placed in the PO when
the buyer creates the Purchase order?
At this moment always the default value from Material
master is proposed.
Thank you in advance,
Eric.

Hi,
You have to look at the overall process.
The idea of the Purchasing Group is to indicate which buyer manages that material in that plant.
SO when the system (or a user) generates a requisition for that item at that plant, the system then knows who should convert it etc.
So my question to you would be, "why have you got a default P group in the material master record that is NOT the buyer who manages that item at that plant?"
If several buyers share a list of materials then just use one P group for the "group" of buyers, instead of separate P groups for each buyer.
The system doesn't have the option to automatically overwrite the P group on the requisition because this may be someone just "helping out" the buyer who is busy and so it does not mean that the requisition should be changed to be linked to this other P group.
You already have the field "created by" on the PO and so if you need to report on who created what, then simply use this field instead of P group.
But the P group on the material master (and therefore the requisition) shoudl ALWAYS be the P group that will convert reqs for this item plant combination.

Authorization Group Material Master

Hello,
i am trying to restrict a user from accessing a single material. I am using Authorization Object M_MATE_MAT for this. When I use transaction mm03 to go on the material master I see a field for the Authorization Group but when I go to the same view in mm02 (View: Basic Data 1) I don't see the field Authorization Group or the section Material Authorization Group. Where can I enter the Authorization Group for a Material Master.
Thanks everyone - I'd really appreciate an answer,
Johannes
Edited by: Johannes Hintsch on May 15, 2009 12:17 PM

HI..
You will have to make the field to display in OMS9.
Double click on MM02 - - >then for number 36 make the field as optional entry or required entry as desired.
Right now it must be showing in Hide.
After changing you will be able to see in MM02 and make the entry there.
Hope it helps,
Swapnil

Change Excise Duty Group on the Material Master

What are the steps to change the excise duty group in the Material Master (MARC- OITAXGRP)? I am getting a message 'Excise duty tax group cannot be changed due to posted stock'.
We realised some of materials have been setup with incorrect excise duty group at a few plants and there have been a lot material movements posted (101s, 301s). But is the best way to fix this?
Do we have to reverse all the documents or is it good if we zero the inventory and then it will allow us to change?
Is a direct table update of the table an option?
Please advice.
Thanks in advance
Srini

you can't change the excise duty group if there is a stock for the material.
there is a steps that you need to follow if you inisist to change:
- zerorize the stock in the current period (all stock types)
- zerorise the stock in previous period (all stock types)
- then only you can change the excise duty group.
these steps can only be carried out when the two posting period are still open, so normally you should do it at month end.

Material group in material master for different plants

Warm greetings Masters of Material Management
We have one material master for three different plants example 1000, 2000 &3000 with same material group with different valuation class
If we change material group in plant 2000 it is reflected in 1000 & in 3000
My question is this the standard practice that material group changed in one plant will be reflected in other plants
Regards
shamul heq

Thank u Amola
The current situation, if user change material group for plant 2000, it is effected in plant 1000 & in 3000
the impact of this is in purchase requisition
As the release statergy is triggered from material group to different department
How can we solve this issue

In Material Master Screen,functionally what is Requirement Group in the MRP

In Material Master Screen,functionally what is Requirement Group in the MRP Screen.Pls explain its functionality

Hi,
The safety time / actual range of coverage ensures that the planned warehouse stock covers the requirements of a defined number of days. It therefore serves as a time float and thus works alongside the safety stock, which acts as quantity float.
The system simulates bringing the requirements forward by the specified number of days and the planning for the receipts, created for these requirements in the planning run, is also brought forward by this number of days.
Prerequisites
·   You have set the Safety Time indicator in the material master record (MRP 2 View) to define whether the safety time is only to apply to independent requirements or to all requirements.
·    In the material master record (MRP 2 View), in the Safety Time/Actual Range of Coverage field, you have entered the number of workdays by which the requirements are to be brought forward.
·    If, in addition to this actual range of coverage, you also want to define a different number of workdays in certain periods or a safety time less than one day then, in Customizing for MRP in the activity Define Period Profile for Safety Time/Actual Range of Coverage you can define a period profile and assign it to the material in the material master record.

Multiple group - single material master data

Dear friends ,
I am doing material master data as follows.
Ex. Water Bottle - Material Group - may be (Aqua) or (Bislary) or (Saiganga) or (Balley).
means when i will make material master it will become 4 material master with 4 group as bellow.
1) Water bottel-Aqua
2 )water bottle-Bislary
3 )Water bottle-Saiganga
4) Water bottle-Balley.
By my requirement is that it should be only one material master code , with facility of 4 material group.
Whatever i need i will select at the time of PO.
Regards,
Mahesh.

Hi,
You just go for single material code creation as WATERBOTTLE and then as you needed, you can go for Split Valuation where same material WATERBOTTLE at a plant can have different stock quantity and value for different groupings {(Aqua) or (Bislary) or (Saiganga) or (Balley)}
http://www.sap123.com/a/29/#split-valuation
OR
Go for Batch Management where you are just subdividing the material WATERBOTTLE according to the characteristics{(Aqua) or (Bislary) or (Saiganga) or (Balley)}
