Change of Material Type via MMAM

Hi All,
May I ask what are the other prerequisites in changing the Material type?
What I know is stocks must be zeroed out, Open POs must be closed (is it the open POs only? or all POs with the specified material?) ,and OLD and NEW Material type should have the same Value and Quantity Updating setup.
I tried changing one material by it reflects an existing Delivery for the said material, I checked the DR and found that it was already received - although its Shipment Cost hasn't been transferred. What should be done with these DRs?
Thanks a lot.
=)

Hello
The following are the checks the System made :
The POs will need to be flagged for deletion and/or the production
orders will need to be archived, in order to change the material type
for the material.
The value and quantity updating must be identical for the old and new
material types in order to allow a material type change.
Review note 160970.
If you do not want to flag the deletion flag of the PO line item for
the material, please use note 160970.
Note 160970 is only for material types where the quantity and value
updating is similar (txn OMS2 configuration) .
Please refer to the Online documentation:-
    Logistics - General
    -> Logistics Basic Data
       -> Material Master
          -> Material Master Records
             -> Material Types
                -> Changing a Material Type
If the material is already in stock, or if reservations or purchasing
documents exist for it, the following conditions must also be met:
o Quantities and values of the material of the new material type
    must be updated in exactly the same way in all plants as quantities
    and values of the material of the old material type.
Please take note that the account category reference must be the same
for both the new and old material types and the stock values for the
materials with the new material type must be updated in the same G/L
account as the stock values for materials with the old material type.
Regards,
Mauro

How to clear the PPC balance to change the material type?

Dear experts,
Our customer need to change some material type (valuation class as well) from semi-finished product to purchase part. It uses Product Cost Collector for semi-finished/finished product and never makes settlement for any PCC.
To change the material type through MMAM requires zero stock and cleared PCC balance. So we removed the stock of the semi-finished product and settled the PCC for every month of this year.
Since the products could have entry this year and last year, even if we settled their balances of this year, it still can not be changed the material type.
And we do not know how to settle the PCC balance of last year because only one field YEAR can be entered on screen KK87/CO88. If I enter settleme period 11, posting period 12 and fiscal year 2007, system will give error "Period 12 is not allowed".
But we happend to find one product has no entry this year but has balance value of last year. Its material type can be changed w/o any errors, which seems last year balance has no impact material type change. I get confused.
Can any one advise whether I'm wrong and where?

Hi Sharan,
Matl Povided to Vendor stock will appear in Subcontracting scenario.
If at all you have given some material to a subcontractor , this will be consumed automaticaly when you will recieve the ordered material from subcontractor.that is 543 movement will take place in the backgroung when u do the GR.
In case if u need to clear the stock u can do 542 and take the stock back to unrestricted.

Hi,
While changing the Material Type, following points needs to be confirmed :-
1. There should be no stock against the materials. If there will be any stock against the materials, then u will have to nullify the stock for the materials.
2. There should be no open documents against the materials like PO, PR etc. In case if any open documents, same needs to be closed.
3. Also there should be no open reservation order against the materials.

Change of material Type

Hello to all,
I have one question. We are doing implementation with SAP R/3 version ECC 6.0. First let me explain the scenario. The scenario is Intercompany sale. We have two Statergic Business Units e.g. 'A' & 'B' . One SBU ('A') isues PO for manufacturing Press Tool to other SBU ('B') for which it will be SO. . ETS is operated through Project System Module for which Tool is a FERT (Finished product). Now 'B' manufactures the tool and delivers & sales it to 'A' with the material type as FERT whereas for 'A' it is FHMI (Production resource tool). The problem is that both the Statergic business units are operated through SAP with same client.
Kindly provide the soluion. Please feel free to ask any furthur clarification required.
Thanks in advance
Sudhir

Hi,
If you want to change the material type, you can try in T.code: MMAM
But in your scenario, u just go for BOM in T.CODE: CS01( example: in a finished products how many parts are there).You can have PO for parts and SO for finished products.
Hope this will help.

Change of Material Type in Plants

Dear Guru's,
Good Day.
I've two plant Codes Plant A and Plant B with one company code.
Plant A Procures a Material(ABC) from an Vendor. Material type for ABC is maintained as ROH(Raw material).
Plant B produces Material(ABC) inhouse and does STO to Plant A.
I've extended the Material (ABC) from Plant A to Plant B.
Now, I need to Change the material Type for ABC in Plant B as Finished Goods(FERT), which is not Possible by transaction MMAM.
I need to Change the Valuation Class and Price control for mateiral ABC in plant B.

Changes of Material type

Hello All.
I have created a Material master and by mistake i have put wrong Material type, so now can i change that material type for that material master.
please suggest.
Regards,
Vishal

Hi,
Before changing material type check whether any stock is there for that material also check open purchasing & sales docs. If you are changing the material type use T.code MMAM once you change the material type valuation class of the material also changes.

Change the Material type & Material industries

Hi Expert,
I have created one material code. Suppose that Material Code is " XYZ"
Material code : "XYZ"
Material Type : FERT
Industry sector: Chemical industries
I want to Change material type & Industry sector.
Please help me how i change the Material type & Industry sector.
Best Regards
Shashi Singh

Hi
I want to Change material type & Industry sector.
Changing the material type for a material is possible as it has been well explained by other friends
It is because a semifinished goods one material type can become a finished goods another material type
Changing the industry sector is not possible at all
Once industry sector is assigned to a material you cant change it at all

Changing standard material types

Hello All,
We are using ECC 6.0
I want to change few settings for standard materials types like FERT, HALB, ROH and HAWA.
For example Standard FERT does not have Purchasing view enabled but I enabled it.
Will these settings be reset when we go for upgrade in future?
Thanks
George

Hi,
You can change settings related to std config, depending upon your clients requirement using T code OMS2. In that case once you make changes in std config then all materials are created with purchasing view.
But it will reset after you upgrade your system in future as these are standard SAP settings.
As our collegue mentioned it is better to create another material type instaed of changing std material type.
Hope this will resolve your issue.
Best Regards,
Avinash.

Change material type - any warnings?

A material with very little history exists in the system as a semi-finished item with 1220 valuation class. One purchase order exists that is due in, in two days. No inventory exists. The problem is that the system is not configured to post goods against 1220 valuation class items. So it needs converted to a finished good since the plan is to sell it after it is received from a vendor.
No open orders or other movements exist in the system. Just one new open po that was created today, and could easily be deleted.
So, delete the po then change the material type using MMAM.
Are there any recommendations/warnings someone can offer before this is done?

Hi,
Pre requisites for changing a material types:
1. If you use a material ledger the material ledger must be settled in it.
2.If the old material type did not require you to specify a price control for the material the new material type must not be configured such that it allows only
standard price as price control.
3.If the material is already in stock or reservations exists or purchase orders exists the following conditions must exist.
      1. The stock values of the new material types must be updated in the same
          G/L Account as the stock values of the old material types
     2. Quantities and values of the new material types must be updated exactly as were by the old material types.

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.

Changing Material Types

Gurus,
I have a situation. We have multiple Plants under different CC with common materials being traded between different Plants. A raw matl for one could be the FG for another and such similar cases. Now when I am trying to onboard a new Plant in my landscape, I notice that certain materials are FERT for me, but they have already been defined as ROH in the system.
We have agreed to change the Matl types to a new common one. Please tell me the steps and precautions to be taken while doing this activity.
Regards
Keshav

Use t.code: MMAM - for changing the material type but you change the material type in MMAM transaction automatically also the valuation class will be changed in material master. The system will take the changed material type valuation class which was created for that material type.
If valuation class changed, U have to take care of..
1) Valuated stocks in the current period or in the previous period.
2) Open purchase orders may be there.
3) Production orders which a goods movement has already taken place.
For this first you have to do the following:
If valuated stocks already exist, you can change the valuation class only:
1) Post the stocks of the material to an interim account.
2) Change the valuation class in the material master record.
3) Post the stocks of the material back to their original account.
If open purchase orders already exist, you can only change the valuation class if you first flag the corresponding purchase order items for deletion.
If production orders exist for which a goods movement has already taken place, you can only change the valuation class if you first set the status of the production orders to deleted

Modifying of material type

Hi,
I have created one material in MM01.
Selected material type is Rawmaterial,but I need to change this into finished goods type.
How to change the material type and aswell as valuation class for that particular material.

Hi
Before changing material type please ensure that there are no open PR/PO/contracts /Scheduling agreements .In case if any one of them exists then you need to set deletion indicator for all such open PR/PO/contracts /Scheduling agreements .
First Goto Transcation code MMAM - This tcode is for changing the material type from ROH to FERT and not valuation class.
If you change the material type in MMAM transaction automatically the valuation class will be changed in material master. The system will take the changed material type valuation class which was created for that material type.
Second Goto T code MM02 - Accounting View 1 - This tcode is to change the valuation class directly.
Whether you can or cannot change the valuation class directly without changing the material type depends on your own company img settings.
If you want to change the valuation class, there may be because of one or more of the following already exist for the material:
1) Valuated stocks in the current period or in the previous period.
2) Open purchase orders may be there.
3) Production orders which a goods movement has already taken place.
For this first you have to do the following:
If valuated stocks already exist, you can change the valuation class only:
a) Post the stocks of the material to an interim account.
b) Change the valuation class in the material master record.
c) Post the stocks of the material back to their original account.
If open purchase orders already exist, you can only change the valuation class if you first flag the corresponding purchase order items for deletion.
If production orders exist for which a goods movement has already taken place, you can only change the valuation class if you first set the status of the production orders to deleted
By this you can keep the same material type as FG and can assign the proper valuation class.

MMAM - change material type

When we try to change the material type of a material we often get the following "error" messages:
The material type cannot be changed. The reasons for this are:
stock already exists in the following plants
purchase orders exists
We want to change the material type automatically (via program) but then we need to catch these errors ---> so we need a workaround to be able to change the material type.
Can anyone help us with this workaround ---> any known program/function/... for this issue?
Kind regards,
Lieselot

I don't want to create a way around these issues. I just want to put these actions into a program so we don't need to do them manually.
Kind regards,
Lieselot
