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)

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.

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???

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.

Prasobh

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.

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....

Base unit of measure issue during CIF

Hello,
we have one APO system which is connected to two R/3 systems (System A and System B).
Actually one product number was coming years ago from System A with base unit of measure EA.
We now need to add the same product number (with a different Business system group) via CIF coming from system B, but the source base unit of measure is ST.
CIF interface stops with error "Error Text: Base unit of measure for product xxx" ....
So actually I am looking for a way to add product xxx to the integration model in System B and transfer data to the APO system without removing the products and all linked master and transaction data from APO and creating new data.
Maybe there is a workaround ...
Thanks for any ideas and thoughts.
Kind regards,
Andrea

Andrea
One way is to add ST as alternate unit of measure in APO product master . This is because you cannot change the base unit of measure in APO without deleting all the dependent objects.
After that you will be able to CIF over the data . But then you have to remember one thing . Whenever you change the material master for this material in R/3 and CIF it over , the alternate UOM ST will get wiped out in APO and you have to maintain it manually.
Thanks

Hi
Changing data directly in the table is not advisable, as this will disturb the data in the other tables as well.. using the debug functionality in SE16N you can chnage the UOM .
There are so many dependencies that you certainly step into the one or other problem

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

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...

Base unit of measure is cahnging after creation of material master

Hi
I have created a material with material type Raw material with BUM "Ton" , after save the material, when iam checking the material with display mode, the BUM is changed into "EA",i dont know where the sustem picks the BUM as "EA", kindly suggest where i have to do the configuration settings.
Thanks

Hi,
Have you created the New Material referencing from another material.
Please check the following links for details. It should be able to answer your queries.

QM_Change of base unit of measure not possible

Dear QM Experts,
Scenario is,
1.     Material master created with QM view activation.
2.     The Base Unit of Measure kept as EA
3.     Inspection plan prepared for material with usage 5 and status 4.
4.     Material has not undergone any purchase order / production order / routing or any other transactions except inspection plan.
5.     No movements have done and the stock is zero
6.     The requirement is to change Base Unit of Measure from EA to KG
When tried through MM02 system throws an error message as The base unit of measure cannot be changed; choose "Display errors" Message no. M3189
When viewed through log another information gets displayed as Routings already exist that are assigned to the material. Task list type Q.
I tried through trial and error method. First material assignment was deleted from task list, problem did not resolve. Thereafter deletion flag put to task list. No impact. At last entire task list deleted. Still system does not allow changing unit.
Has anybody faced the same problem ever? Whether deletion of task list (By T-Code QSR6) from data base will server the purpose? What are the obligations that one must follow while execution QSR6?
Or if there is any other solution to this requirement?
Thanks in advance
Best Regards,
Anand Rao

Hi
*What are the obligations that one must follow while execution QSR6?*
By this T code Deletion is very much possible provided that
If there are no stocks of the material in the current period and in the previous period
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).
If no purchase requisitions, purchase orders, or scheduling agreements exist for the material
Material Is used in any task list/Rauting.
Now as per your schenario I hope you have checked Inspection lot & PR,PO.
Error showing Q type of task list.
Go to PLKO & MAPL table for this material & group & Gr counter check the entry.
Check deletion Indicator in both the tables. If it has status "X" then this task list is very much possible to delete through QSR6.
I hope this will add some value to your Execuation.

Base unit of measure

Dear Expert
my query is whenever i add new base unit of measure what are the effect it had on the system , i mean how base unit effect in the back end ...how system process base unit of measurement .
Regards

Dear usmfarhan
Actually Base unit of Measurement is the UoM which u want to maintiain ur inventory in the system.
i.e whater u r buying it from vendor ...it might be in Ea or Box or Carton
And you want to store in KG
So you can have Additional unit of Measurement and its conversion that can be defined in AMterial master in additional unit of measurement
Let us say Base UoM is KG and ur Ordering unit is TON
So u have to define Conversion rule as 1 Ton = 1000 KG in material master.
,While changing Base unit of measurement you should make sure that stock should not be there.
Secondly neither Purchase order for Raw material not Sales order for FG should exist in the system ,Neitehr routing should exist for FG
Or else system will not allow u to change UoM
