Dear all
I am facing the following issue,
Item category N: Only base unit of measure EA allowed
Message no. CO344
Diagnosis
You have entered a unit of measure for a component of the item category N which does not correspond to the base unit of measure maintained in the material master record.
Procedure
Use the base unit of measure maintained in the material master record.
Please give the solution for how do handle that issue.
Thanks&Regards

Hi
My requirement is: The item category N should allow me to use alternate UOM.
When i checked with Item category L, the system allows me to use alternate UOM. I need the same to work for Itm category N also.
Through forums, i found that, in standard SAP, system will not allow to use alternate UOM for Item catedory N.
Is there any config settings to be done for my requirement?
Kindly do the needful.
Thanks & Regards,

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

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)

Hi
Please maintain the translation in the Following Configuration
Logistics - General->Material Master->Configuring the Material Master->Define Structure of Data Screens for Each Screen Sequence
Select the Specific Screen Sequence & Maintain the languages
Similarly please maintain the Translations in the Transaction CUNI for the Base UOM in respective languages
I hope currently in your system only Language EN is maintained

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

Base Unit of Measure to Sales Unit Conversion

Hi,
Currently we are selling material in MT and all other transactions in MM and Production are in MT only.
Now client wants material to be sold in Meters, also in some cases the same material will be sold in MT also.
(As per my knowledge generally if the conversion is one to one i.e. base unit of measure is pieces and Sales unit of measure will be boxes and
1 box = 10 pieces can be maintained in material master.)
Here for conversion between Metric tonne to Meters there is formula involved so how and where this conversion needs to maintained in system.
How to map this type of scenario.
What all activities needs to be done from SD side and which other modules need to be involved this process.
Note: SAP is installed for more than 3 years now.
Hope i clear enough.
Regards,

Hi following is the formula.
OD = Outer diameter, thickness, length, Number of tubes are maintained in sales order charateristics during sales order creation.
OD
Thickness
Weight in Kgs / M
length of tube
Nos of tubes
Total length in Mtrs
Rate / MT
Rate / Mtr
A
X = (A-B)*B*0.02456
'L
N
T= L xN/1000
R

Converting one base unit of measure to another

Hi Experts,
i want to know the function module name , which should convert the one base unit of mesure to another base unit of measure.
like EA TO PAL , or PAL TO sqft.
i have found one function module ( MATERIAL_UNIT_CONVERSION) ,which is not giving proper output(giving only zero's)
could u please help me out from this problem.
Thanks in Advance,

Hello,
Try this.
data:c_kg LIKE lips-gewei VALUE 'KG', "Weight unit in kg
c_lb LIKE lips-gewei VALUE 'LB', "Weight unit in lb(pound).
CALL FUNCTION 'UNIT_CONVERSION_SIMPLE'
EXPORTING
input = i_ln_items-brgew
unit_in = c_kg
unit_out = c_lb
IMPORTING
output = i_ln_items-brgew_lb.
If useful reward.

BOM Unit Different from Base Unit of Measure

Dear PP Experts,
I have following Scenario in some of wires which are .
Base Unit of Measure - Coil
Conversion Factor
1 Coil - 100 Metres (Already Maintained in mm01)
Suppose, one manufacuring item consist of 0.5 Metre of Wire. We want to use Metre in BOM, how can we use it.
Please help, full points if helped.
Ishu

Dear,
In material master you maintin alternate unit as meter in plant data/storage 1 as unit of issue This will default this unit in BOM item
In the BOM, in the component enter the above material code and enter the qty as 0.5. system will default meter as the unit of measure in BOM.
Please come back if required

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 measurement while saving production order

Hi
While saving production order I am getting following problems:
"Material has no base unit of measure"
Whereas UOM is there, I also can see that as soon as I enter qty while creating the order. System automatically prompts the UOM.
I also donot find any problem in MRP run, planned order creation etc
So what can be the problem?
Edited by: BNR on Nov 24, 2008 5:22 AM

Dear,
It may be data base problem as you are getting this problem fequently so please check with Basis person.
Have you defined the any production unit in both material master WS view & in routing or any other alternative unit of measurement please check?

Base Unit Of Measurement error

Dear Sir \ Mam,
Our some materials base unit of measurement is in KG, and we want to make bills, excise RG1 entry in KG for milligram sales or material transfer. How to go for such transaction, system is not allowing for such transactions.
Pls Note : We can't create two separate materials code for these UOM issue materials.
Requesting a help.
Regards,
Randhir Padwal

Hi,
As per my understanding you have base unit in KG and you want to material issue and sales in miligram unit. If this is requirement then you may try to assign "sales unit" for material master in "sales:sales org1" view. you have to also give the conversion rate from KG to miligram in additional data.
for issuing you have to maintain issue unit "miligram" in material master view "Plant data/stor1"

Material Master MATMAS IDOC and base unit of measurement

Hi
We are using SAP standard material master IDOC type MATMAS05 to trigger IDOC. Our material master is having base unit of measure as "G". We are not using ISO unit of measurement. But Material master IDOC, segment E1MARM is populating base unit of meaurement (MEINS) as "GRM".
Any idea why IDOC is picking ISO unit of measurement instead of material master base unit of measurement.
Any idea how to send base unit of measurememt as "G" instead of "GRM" in DOC segment.
Thanks
Nilesh

There are ISO codes for country keys, currency keys, units of measure and shipping instructions. According to SAP design guidelines, you should use ISO codes for an IDoc if they are available. When you set up the IDoc, the SAP codes have to be replaced by ISO codes.

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.

How to correct CIF error Base unit of measure does not exist?

Dear experts,
I'm trying to cif a location product with base unit of measure KG in R/3 and alternative unit of measure well maintained.
it gives me a CIF queue saying that
"Base unit of measure ZXX does not exist (Product 0000000000000XXXXXX has not been created)"
I do not understand why, the unit ZXX does not exist in the alternative unit of measure for any of the materials managed
I also checked CUNI table and ZXX is not there neither in R/3 or APO,
Thanks for your help
E

Looks like the Alternate UOM --Zxx is not maintained in APO.
2 ways to do this:
(1) program- RSIMPCUST
Re transfer all your UOM settings from R3 to APO
(2) Manual Maintenance in APO:
SPRO>SAP NETWEAVER>GENERAL SETTIGNS>Check UNits of Measurement
Thanks

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.
