Material Type Change Implication

Hi all,
What are the implication of changing the material type of existing materials?
Kiki

Hi Kiki
Implication of material typpe change. First of all you can change if the stock is nil.
1) If you have maintained different storage location for different material type. The location will change.
2) Further The valuation for each material type is different.
we have to change accordingly.
3) Screen group selection is based on the material type, this will change.
4) Procurement type will be based on the material type.
5) Material group is based on material type.
6) Even base unit will be different for different material type. in some industries for Ex FERT and HALB will be in PC, EA etc., and ROH will be in Kgs.
Hope this will clear your doubt.

Material Type Change (Val Category Error)

Hi,
I have a problem, I have to change material type of one material. There is stock of that material is 50. I have adjusted the inventory as zero (mov 702) in the current date. Then material type changes thru T-code MMAM, but I want to insert valuation category Z in teh mateiral master, as the material is split valuated. But when maitaining val category display error is coming " valuated stock exist" but there is no stock available. Do I have to zero the stock in the previous period also, if yes, can somebody tell me how to do.
Or there may be another reason.
Full points to helping answers.
Regards
GR

You can only change the valuation class or valuation category under the following circumstances
u2022No stocks are available for the material.
u2022There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material.
u2022At present, no purchase orders or purchase order items are being created or changed.
If system is not allowing changing valuation category there will be either stock of this material or existing purchase document
1) If there are stocks in the previous period, you can clear them as follows:
a) Post the stock in the previous period to the current period (for example, using movement type 561) so that the stock for the previous period is the same as the stock for the current period.
b) Clear the stock with the posting date in the previous period (for example, using movement type 562).
u2022 2) If there are Open purchase requisitions, purchase orders, or scheduling agreements for the material, close it.

Material Type Change

Hey Guys,
I like to make change in the material type. What things I need to consider for that? Both the parts have different valuation class but Account category Ref is same. Is there going to be any financial impact? The other thing how I can move the inventory in mass and how I can upload the inventory in mass after changing the material type.
Thanks in Advance.

Hi,
please ref.
http://help.sap.com/saphelp_dimp50/helpdata/EN/ff/515ae349d811d182b80000e829fbfe/frameset.htm
In you case, having same Account category Ref wont help you, since the account determination for the material type would be based on Valuation Class.

Spilit vauated material type changing

Dear Sir
How to change the material type which is subjected to split valuation
Thanks
Maruthi

Hi Vikas,
Check the attributes of the material types, it should be same for both of them, i.e the quantity and value update should be same for both old and new material types.
Also check if there are any open PO's against the Old purchase order.
The account category reference should be same for both the material types. check in the config for the accont category reference.
hope this helps..

Error during Material type change

Hi,
We are trying to change a material type from being a purchased raw material to a manufactured semifinished part using MMAM tcode and getting following error.
The Purchase Order displayed is already received & invoice complete.
Error****************************
Purchase orders exist
The two material types have either different quantity/value updating or a different account category reference.
PO number      Item
P048019        00140
Could you please let me know how to overcome this error..?
Thanks & Regards,
Samay

Samay, I hate to be the bearer of bad news, but the only way to change the material type on a material is if the material has no links. No Purhase Orders against it, no reservations against it, no inventory, etc, etc. The material needs to be "Clean" to change the material type. If it is a fairly old material, this may be a huge task, which is why I suggested just to create a new material and go with that. You would need to do some major clean up to get the material to a state which would allow you to change the material type. I guess you could start by removing the item from the PO which you mentioned earlier. This is only the begining though.

Material type change for split valuation

We have to change to material type for materials having split valuation.
Suggest the required

The material type is stored in table MARA, however, MM17 can not change all fields that are contained in a table. MM17 is not a table modification tool, it just supports business process of mass changing some field contents. It is more like mass process MM02. But the fields that cannot even easily changed in MM02 like base unit of measure, batch managment flag are not supported within MM17. Material type cannot even be changed in MM02.
There are that many checks that need to be performed and cause a failure, that you cannot do such in a mass change transaction.
It is certainly possible to record MMAM to finally do this with batch input, CATT or LSWM for many materials. But first try it manually for 10-20 materials to make your experience.
By the way, dont forget the number range. If you change material type, then the material number will remain, which may screw up your number range logic (that is often defined after heavy and long discussions. If you have different number ranges per material type, then you should block the transaction MMAM for anybody)

Regarding - Material Type Change

Dear All,
I want to change the material type. Eg. We have material code A (HALB). We have did not used from implementation. Now i want to use the material as a ROH,
but i am not able to change the mateial type, kinldy tell me the flow to change the material type. This material did not have any movement, any open PO`s.
This is very urgent.
Thanks in advance.
Reg/ Shankar G.

Hi,
If you try to change the material type the system will give you the details of why it cannot be changed.
Please try MMAM and look at the rror log it will give you.
If it wil not allow the change then there is definitely some transaction somewher that will need to be deleted etc.
Let us know what the erro log say and we will try to help.
BE CAREFUL - Don't think that the informationmessage is stopping you. The system will issue a message telling you that you are changing the material type from X to Y, just press enter and the change will take place (or you will get details of any errors).

Material Type Changes

My client currently has all materials created as NLAGs but wants to start tracking inventory.
They do not want to change the material number.
There are sales orders active for materials.
Can anyone give me some guidance on all the things we need to watch when changing the material type?
I'm not certain what if any financial acitivity is associated with the materials today but somehow think there is none. We have active orders and need to ensure the material with the new type replaces the old material with the wrong type - don't forget it is the same material number.
Thanks for any input.

you can change the material type from NLAG to any other with transaction MMAM. SAP will tell you
But this is only one part of the medal.
Even your material number stays, Idoupt if your current sales orders/deliveries can handle the new siuation with inventory that needs to be issued. For NLAG materials you usually use a different item category in SD than for inventoried materials.
MMAM makes a lot checks, and I think you cannot even perform MMAM if orders exist for your material.

Change material Type - 'MMA'

I am trying to Change Material Type using T-code - 'MMAM'.But Message is coming PO already exist.
Problem is tat we have already created GIN for the PO & Reversed the GIN also,but still PO is not getting release to Change any data.It is giving error,that GIN already exist.
I want to Change the MAterial Type.How can i do that.??
Viru.

Please note that both the new material type and the old material type must have the
same characteristics eg. quantity based material management is one of
the characteristic. The R/3 Online Help provides a very good explanation
on all the pre-requisites before you can change a material type.
(Logistics Gen>Logistics Basic Data > LO Managing Material Master Data >
Material Master Record > Material Type > Change Material Type)
Please check if you have set the deletion flag for any PO's as
these need to be physically deleted for MMAM to work. You will also
need to check if there are ANY open items for this order. The purchase
orders need to be ARCHIVED. You should complete the invoice receipt for
this position BEFORE you set the deletion flag in the purchase order.
Also, if the material is already in stock, or if reservations or
purchasing documents exist for it, the following conditions must also be
met:
>The stock values of the material of the new material type must be
updated in the same G/L account as the stock values of the material of
the old material type.
>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.
>If there is a transfer requirement for the material and if quantities
of the material exist, the new material type must also allow the
material data to be maintained from the Warehouse Management view.

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

Issue in transporting changed material type using ALE-IDOC

Hi All,
I am sending the material master data from one system to another using ALE-IDOC.The issue is that teh material type is not getting sent from one system to another after changing the material type.I mean the changes in material type are not getting updated.I will be indeed thankful if anyone can guide me resolve this issue.
Thanks.

Hi,
Not all the fields that are changed in material master are sent in the Idoc. Material type is one such field.
Create change pointer on some other field ex. net value or material desc. and transfer the material type changes under it.
KR Jaideep,

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.

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.

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.
