MMAM - how to change material group

Hi guys,
could you pls tell me all conditions that must be fulfilled when I want to change material group in MMAM?
current group - HAWA, new group -ROH
thanks a lot,
I

Hi,
   I believe you want to change material type. Below are the prerequisites to change the material type:
1. If you use the material ledger, the material must be settled in
2. If the old material type did not require you to specify a price control (for example , standard price or moving average price)
      for the material, the new material type must not be configured such that it allows only standard price as the price control.
3. If the material has been maintained from PRT (Production resource tools) view, this view must also be allowed for the new material type.
4. If the material is not configurable material, the new material type must not be allowed only for configurable materials.
5. If inspection plans are required for quality management inspection of the material, they must be allowed for the new material type.
6. The material type ID indicator(presently used only in Retail) must be the same for the old material type and the new material type.
7. If the material is already in stock, or if reservations, or purchasing documents exist for it, the following conditions must also be met:
   A) The stock values of the material of the new material type must be updated the same G/L account as the stock values material of the old material type.
   B) Quantiites and values of the material of the new material type must be updated exactly the same way in all plants as quantities and values of the material of the old material type.
C) If there is a transfer requirement for the material and if quants of the material exist, the new material type must also allow the material data to be maintained from the warehouse management view.
8. In Customizing for the material master , the following indicators must have the same setting for the old material type and for the new material type:
A) Material for Process Indicator
B) Manufacturer Part Indicator
9. If the material , whose material type you want to change ,was handled in batches and if,due to the maintenance statuses of the new material type, the material can no longer be handled in batches,although batch still exist, you can not change the material type.
Thanks,
Venkat

Change material group for an existing material

Hi all,
What is the steps to change a material group for an existing material?
Is there any impact on the reports if I were to change the material group of an existing material?
Thanks and regards,
JT

Yes, You can change in MM02 and also while changing you will get the folloeing Warning message..
You are changing material group, but material already used by purchasing
     Message no. M3531
Procedure
     When changing the material group of a material that is already being
     used by the purchasing department, you should note that:
     o   The purchasing statistics show how much of a material group has
         already been ordered. Unitl the change is made, the material is
         managed under the old material group and therefore the old material
         group statistics are updated. From the moment the change is made,
         the new material group's statistics are updated.
     o   Some purchase orders may derive from contracts with item categories
         referring to material groups. If this is the case, the material
         cannot be used after the change has been made.
     o   Every purchase requisition is allocated to a release strategy that
         can depend on the material group. A new release strategy may apply
         to a new material group. Purchase requisitions that were created
         before the change are subject to the old strategy; purchase
         requisitions that were created after the change are subject to the
         new strategy.

How to change Material Type

Hi All,
I have created new material type as ZINS ( Insurance spares ).
Now,I have to change ZSPR ( Spares) material to ZINS material type.
In system there are no liabilities for this material.But ,I am getting following error while executing T-code :-MMAM.
Error :- " Change Material Type
The material type cannot be changed.
The reasons for this are:
QM inspection data exists for the material. In this inspection data,
it is defined that a plan is required for the inspection. However,
inspection plans are not allowed for the new material type.
    Plant
    1100
    6001
Task lists already exist for specific TL types for the material
The new material type does not allow assignment of task lists for these TL types "
I want to know is there any settings required while creating new material type in quality module,as this error seems to be related to Quality module.
Please help,as this is very much urgent.
Thanks.
With Best Regards,
Rajesh

Hi Vivek and Murali,
Thanks for your answers.
In my question ,I mentioned that,
In system there are no liabilities for this material.I want to know is there any settings required while creating new material type in quality module,as this error seems to be related to Quality module.
I got answer,while creating new material type it was not assigned to in quality module.I need to assign the task list type Q to the new Material type.
I have done configuartion as follows, ( Path: SPRO -> Quality management -> Quality Planning -> Inspection planning -> Assign Task List Type to Material types).
Once again thanks for your help and support.

Rajesh

What are the impacts of changing material group of a Material ?

Hi,
Could some one tell me in detail about the impacts of changing material group of a material that is active in procrement?
Thanks,
Veera

Hi,
If you are changing it from one valid group to another valid group and both will still be there afterwards, then the impact is small, but important.
The data in the Info systems and BW etc. will have been updated with the the "old" material group and so if you tried to compare them you would find differences.
It is something that does happen from time to time and as long as the two groups will still be ther afterwards there should be no reason why this would cause any technical or system problems. The effect is purely on the historic data.
I have seen this done several times in many implementations and so far it has not caused any major problems apart from some reports "appearing" wrong if you compare them against other reports that involve historical movements.

How to create material group hierarchy ?

Hi,
I would like to know how to create material group hierarchy in ECC 6.0
Thanks in advance for your help,
Kind regards,
Yann

Hi ,
The material group hierarchy and product heirarchy is used in SD of ECC 6.0 . These can be created in Logistics General -> Material Master-> settings for Key fields--> Data Relevant to Sales and Distribution-> 1)
define product categories
2)Define material groups
But If you want to make of use of this in SRM ,I won't think it is available . I guess Probably this is avl for CRM .

MEMASSPO - change material group - message ME 664

I would like to change the material group (MATKL) in PO item. In ME22N it is impossible (MATKL only displayed). When I tried to use MEMASSPO I've got a message ME664.
I changed the material group in material master but PO was created earlier. I would like to have the data consistent. What can I do?

Please check this answered link:

How to change material type and industrial sector of the exsisting material

Hi,
There is an issue where user wants to change material type and industrial sector of the exsisting material .Is it posible to do so??
IF not ,how can we delete that material from material master so that another material with same number and required material type and industrial sector can be created.
Points will be definitely rewarded.
Thanks
Rohit

Hi Rohit,
You can change the material type in MMAM trxn code if the material dosenot conatain any open purchase requisitions, open reservations & open purchase orders. Also material stock should be zero.
Remember the new material type should have same attributes same as old material type.
OLD Material New Material
1) Standard Price 1) Standard Price
2) Manufacture part 2) Manufacture part
profile actvated profile actvated
3) Quantity & Value 3) Quantity & Value
Updation in all areas Updation in all areas
4) should have same GL 4) Should have same GL acs
acs
It is not possible to change Industry sector once created.
If you want to delete the Material, you can flag it in MM06 trxn code.

Ashok

How to update Material group code in contracts ?

Hi,
We implemented SAP in my company a year ago. AS you can imagine we need to do some cleaning now we know how it works...
We have change the Material Group code for over 1100 items.
Thing is, the material group code in the contracts do not update automatically.
I see two ways to handel this :
1- re-enter contract
2- delete lines that needs to be changed and recreate them...
I know for sure that both solutions would work but they are time consuming so I was wondering if one of you had another idea ( a quick or at least a massive one would be appreciated...)
Thanks for your help.

Hi,
You can use transaction MEMASSCONTRACT for mass changes to contracts
Caution:- Please use this transaction if you know, else first practice it in sandbox and then use in production environment

How to change material discription at sales order item level ?

Dear Gurus,
We have some requirement need to change material description at sales order item level , but in system it is in disable mode how to change that into change mode in sales order item level?
Thanks in advance
Regards
Venkat

Not possible in SAP Standard.
Instead why not create a Customer Material Info Record in T-Code - VD51?
Alternatively it the requirement to change the Description is only for few Sales Order then create a Text ID & Enter the Description in Text Feild. Then in Smartform program wrie a code which will check for Material Description in the Text first & if not found then take from normal material Description in Sales Order.
But Customer Material info Record seems to be the best solution.
Hope this helps,
Thanks,

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!
Reward if useful.

How to use Material Group in substitution rule

Hello,
Anyone experience in how to use the entry of the material group of a PO, in a substitution rule for accounting documents.
I have noticed the material number can be used within a substitution rule, and is also available in BSEG... so far have not find a solution to do this for a material group.
Please note, this is applicable for PO with no materials (ONLY a material group to use for account determination).
Many thanks,
Daan
