Base unit change

Dear sir
Material have already movement that material comes to stock & account hit, later due to some reason we want to change base unit of measure in material master record , please guide me how to do it ?
Regards
Mahesh

Hi,
Before making changes to the Base unit, ensure there is no stock at the valuation level, No Physical Inventory open documents, No Purchase requisitions and No Purchase Orders.
Trust the material in subject is not batch managed, in case of batch managed material, there should not be any batch stock too..

Error message during Base unit change in material master

Hi
I am getting error message " Independent requirements are already assigned to the
material" when doing change in base unit in material master.
But I do not find any independent requiement for the plant in t code MD04.
Can anybody help me to get a solution for this?
Thanks in advance
Pradipta Sahoo

Hi
Thaks for your reply.
I checked in MD63 and don't find any entry. That makes me suprprise why the error shows as an independent requirement entry exists.
Please reply if you can further help me in this matter to solve this.
Kind regards

Credit note based on AR invoice but base unit changed to Yes

Is there anyway to improve the current design which allow the users to change the base unit column to Yes if the credit note is copied from AR invoice?

What is your reason to change unit? It may not be logical to change it even if you wrongly created your invoice. When you create Credit Memo, it has to be consistent with AR invoice even if it is wrong!

Base unit to change in material master

we assigned base unit of measurement to one of our material code say KM and after that we created routing .When we come to know that base unit is wrong and instead of KM base unit required was KG then we delete routing for the material.After that when i tried to change base unit of meas. in mat master system is giving me error
Routings already exist that are assigned to the material.
   RType RtgGrp   GpC Plant
   N     50013509 1   UHVC
I want to know how it is possible?
Is there anything remain?

If SAP tells you that you have routing, and even shows which one, then oyu have not really deleted it.
BOM Deletion - Transaction CS02, open the BOM header view and select menu "Material BOM > Delete.
Routing Deletion - Transaction CA02, select the routing overview button and select the routing line to be deleted, press the deletion button.

HI
You can only change the BUM if there is no stock production order planned orders reservations, PO s etc are not in the system there should be no transaction of the material ,after ensuring all this, u can change unit of measure

Changing Base Unit Of Measure in Material Master

Dear All,
We need to change the base unit of measure of certain materials who have been assigned inspection plan. We have deleted the material from Inspection Plan and later even the plan. But still the system not allowing to change the BASE UNIT OF MEASURE. The error thrown by the system is : Material is assigned to inspection Plan.
Please guide in this regard as changing the material for us will be a very cumbersome act.
Regards

Hi Rohan,
Please check 'display errors' in MM02 when you are trying to change the BUoM. It will say what prevents you from doing that.
Please check:

Base unit of measure can not be changed since EAN is already assigned.

Hi,
We would like to change the UOM from EA to SET .In order to tag MM # as BOM Header and ZCEN (Serial number profile)but the error massage appears as below print screensystem is not allowing to do so ,throwing following error message:
"Base unit of measure can not be changed since EAN is already assigned."
Could you help to resolve the same.
Thanks,
Amit

Hi,
Thats correct you must be getting Error message M3 341 ,
EAN international article number is tied with material number in basic data view with EAN Category and seperate number range
EAN is a standardized unit that uniquely identifies a material relating to a unit of measure or type of packaging.
The International Article Number (EAN) is assigned by the manufacturer of the material. In this case, the EAN identifies the
manufacturer uniquely. A company can assign EANs using "in-store" numbering techniques known only to the company.
If you still want to change UOM you need to first remove the EAN assigned..please explore further if you have internal number range
for EAN or external ..etc
Thanks

Changing Base Unit Of Measure (Material Master)

Hi
1. How to check this? (Any successful changes in material master only took place when there is no open document from SD, PP, MM & FI for that material. )
2. Base unit of measurement cannot be changed. The reason being material movement history is there in table - MSEG mainly which otherwise create inconsistency in reporting. -
Is this line applicable for current period or previous period in current year or previous period previous year???
3. There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material. -
is this means open / pending purchase orders or the the PO's created in system with respect to material where the GR and IR is already done
4. You can change the base unit of measure if there is no stock of the material during current and previous period----
is this means the term " previous preiod" is previous period in the current finacial year   or its applicable for the previous preiod in previous financial year
5. Post the stock in the previous period to the current period - -
how can we do this???
Vijay

See this OSS note : especially the last sentence:
From OSS note 138767
Within the material master record maintenance, you want to change the base unit of measure (base unit). During the change, the system performs extensive checks in order to avoid inconsistencies in the applications which use the material master.
In particular, the following checks are performed:
The base unit must not be defined as an alternative unit of measure for the material
No International Article Number must be assigned to the base unit
No proportion/product units must be defined for the material
No configurable material must be assigned
The material must not be used as a configurable material
Stock must neither exist for the previous period nor for the current period
No physical inventory must be active
No reservations or dependent requirements must exist for which the deletion indicator is not set
No planned orders must exist
No purchase requisitions, purchase orders or scheduling agreements must exist for which the deletion indicator is not set
No WM transfer requirements, no WM quants or no WM posting change notices must exist
The material must not be a bill of material
The material must not be contained in a bill of material
The material must not be used as a production resource/tool
The material must not be used in task lists
No standard cost estimate must exist for the current or future period
No production orders must exist
No planned independent requirements must exist
No run schedule headers must exist
If the base unit has dimensions, no serial number profile must be assigned
No sales and distribution documents must exist which have status Not processed or Partially processed.
Solution
If necessary, all reasons mentioned above must be eliminated by archiving the objects listed
1) SAP checks this for you. A new button will appear in MM02 and after you click this button to check the error log, you will see which documents exist.
2) I have not seen that an existing movement will restrict the change of a BUoM.
3) No purchase requisitions, purchase orders or scheduling agreements must exist for which the deletion indicator is not set
       it is not caring about GR done or IR done. it telling you that the deletion indicator has to be active. As a deletion indicator can be reset easily, you probably have to archive the documents
4) the previous period is the period before the current period.
   today we have February, hence the previous period is January.
5) first make sure your current stock is higher than the stock of the previous period. if it is lower, then you have to create inventory in current period first e.g. with 202 movement with current date.
Then you issue the previous period stock with 201 movement and previous period date (make sure periods are open in OB52 and MMRV allows posting to previous period).
Finally you issue the left stock in the current period with 201 and current date.
Now previous period and current period stock is zero. After the change of the base unit you have to get the stock back into the system

Change base unit of measure

Hi,
Its me again. I need to change the base unit of measure of a material but a task listw as created via QP01. I tried to delete this via QP02 but i still cannot change the base unit of measure. Is there any way except for deleting the task list via CA98?
Thanks.
Elen

Ellen,
Unfortunately the answer to your question is no..You have to use a transaction like CA98 or QSR6 to delete the Inspection plan from Database. Please take necessary authorisation and delete this plan.
Alternately set this material to with deletion flag and client & plant level status, so that you cannnot use this material any longer. Now create a new material with correct Base unit of measure and use this material.

Changing of base unit measure

Hi Experts,
I have problem regarding the changing of base unit of measure, I already closed all documents of related material, but still it can not be changed
Error message given as
The base unit of measure cannot be changed.
The reasons for this are:
Material staging requirements already exist.
Reserv.No. Item
No Data
awaiting for your valuable answer.
Rakesh

Dear,
Message no M3 189?
Activating the deletion flag or completing the production order technically is not sufficient if you want to exclude the production orders from the check since you can cancel these statuses at any time.
The solution is to set the deletion indicator for the affected orders with the help of Transaction CO78 and to archive afterwards.
Please refer OSS Note 95491and 138767.

Changes in Base Unit of Measure

Hi,
We got an issue,User tried to change the Base unit of Measure from NO to KG.
1.For this material we dont have stock in unrestricted and quality,But it has reservations. 2.It has got Scheduling agreement,3.This material is used In BOM.
So if i cancel reservations,then remove this item from scheduling agreement and delete it from BOM.Will it work further to change the Base Unit of Measure.
Please Do help me in this matter
Thanks and Regards

1) You can only change the base units of measure under the following circumstances
No stocks are available for the material.
There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material.
At present, no purchase orders or purchase order items are being created or changed.
Item is not linked in any BOM as chield part
If requests for quotations, purchasing info records, or contracts are available for a material, the system emits a warning while changing base unit of measure. Still if you want to change unit of measure specify in a dialog box the factor for converting the base unit of measure into the new base unit of measure. The purchasing info records are then, if necessary, updated.
2) Solution
   As system is not allowing changing base unit of measure 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).
2) If there are Open purchase requisitions, purchase orders, or scheduling agreements for the material.complete all P2P cycle for open orders (purchase requisitions, purchase orders, or scheduling agreements) and then close it.
3)Delete item from BOM
Then
1.     Run Trnx MM02 (Change Material Master immediately.
2.     Overwrite the old base unit of measure with the new one in basic data screen.
3.     Save the change.
3) System checks
If a change criterion (Trnx. code MM02) is meeting all necessary prerequisites (as mentioned in point 1).System allows changing base unit of measure. Otherwise it displays warning or error. U can display the reason for this, by choosing Display Errors (ctrl+F1)

Can we change Base unit of Measure ?

Hello,
I got a requirement to change the name TO(tonne) base unit of measure in MM01 into MT. Is it possible to achieve this if ys share me the procedure.
In short when i click F4 help in base unit of measure in the place of TO i want to change it into MT.
Thks

If u want to change the base unit of measure... firstly do the conversion method... MM02 (If the material is a finished or semi finished) -> Work Scheduling View -> Put the UNIT OF ISSUE (MT) and then give the conversion factor unit measure.... and save...
if u want to change the base unit of measure... Change the MRP PRofile and then change the Base Unit of Measure...
It is better to consult PP and MM Consultant....
I think you got the solution... Give me the point....

Change Base Unit Mesure

Hi Experts,
Is there any form or report or ABAP program to make a massive change of base unit mesure of a material that has stock, POs, Process Orders, etc.? This is because this material has a lot of operations and is impossible to eliminate all documents.
Thanks in advanced.

Hi,
As per OSS note 138767 there's no easy solution, you have to eliminate all problems that prevent your from the change (you have to ekiminate stock, archive...).
In case of batch management indicator change there's a special SAP solution (OSS note 533276) that changes the indicator w/o eliminating anything in the system. But this solution is not FOC (you have to pay to SAP AG)...
But I'm afraid that in case of BUoM change there's no such OSS note... (You can contact and ask SAP to confirm this).

Follow up material with different base unit of measure

Hi all,
I have the BOM with material Mat1 as a component. The base unit of measure of Mat1 is KG.
Is it possible to replace Mat1 with Mat 2 material in MRP once the Mat1 warehouse stock is depleted.
The base unit of measure of Mat 2 is KGK.
The required quantity of MAT1 should be recalculated from KG to KGK accordanly unit ratio.
Please, expain, where does it maintain?
Thanks,
Peter

Hello Peter,
You can use follow-up setting (set Mat2 as follow-up of Mat1 in MRP 4 view of material master if this follow-up scenario is valid for all BOM) with discontinuation indicator '1', w/o effective-out date. In this case Mat1's stock will run out (no PldOrd, PR, etc) will be created, and from the date, when Mat1's stock runs out, MRP will calculate with Mat2.
As I told you, according to my best knowledge, you cannot realize this with different base unit of measures. (you have to change the buom of one of the related material masters or create a new material master if you cannot cope with buom-change).
Follow-up group scenario can also be used but I guess different buoms will be a problem in that case as well.
Maybe there are better solution but I'm not aware of it...
