Material Base unit

Dear Gurus,
I created material XYZ which have base unit (Drum= DR) and "unit of measure 209 Liter = 1 DR". Issue unit is Liter= L. While creating automatic reservation though maintenance order (Required quantity is 50 Liters). The following problems we are facing;
1. When we are going to post the reservation system shows 209 L instead of 50 L.
2. 209 L is in change mode so we post 50 L, but using standard report MB25 in difference quantity column shows 0.761 drum instead of 0.
Note:
When creating order from mb21 > mov. type 261. report shows proper values.
I also tried IW13 which is much helpful. But how to restrict the required quantity for posting.
Regards
amahmood

Hi ...
Generally,1 barrel or 1 drum consists of 209 Ltrs of oil.So,when ever u want to consume say 50ltrs,system won't allow u to consume as u have already defined 1 DR = 209 Ltrs.
Alternatively you can issue the full drum of 209 ltrs from the WareHouse against your requirement and then consume and post according to your requirment.
I hope this justifies your requirement.

Diff bet Base Unit and Order Unit

Hi All,
I was going through the table MARA. I found tht there are two columns named 'Base Unit' n 'Order Unit'. I found interestingly that for couple of materials the units are diff in both coloumns (e.g: For a material Base Unit is EA but the Order unit is in KG). What is the diff bet Base unit and Order unit?
Please inform how is it possible to have two diff units for a single material??
Thanks in Adv.

Base Unit of measure is generally the smallest unit that can be used for a material.
But a company may never issue orders in this base unit.
So in the material master, order unit can be configured which may be separate then Base unit.
As a result orders will always will be placed in this unit.
For ex:
Base unit is set an Inch but the company always issues material always in foot.
Therefore in the material master Base unit of measure is set to Inch and Order Unit of measure is set to Foot

Base unit of messure

Hi expert
i have a raw material with base unit of messure in kg which was assigne in BOM as kg
but recently one vendore supllying the same material as base unit of messure in meter
Now i want to change the material base unit of messure as Meter how it is possible
i have stock in kg aroung 50,
Faisal

We can add alternative base unit of messure in bom?
Dear You should create BOM componenets in Base Unit of measure or Unit Of issue.
In case of BOM component maintain Unit of issue as meter in plant data storage location view In Material Master and add the Item in BOM-CS02.

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...

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.

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.

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.

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.

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

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

Cheking the material for base unit or convert it to base unit.

Hi friends,
I have a requirement asa follows.
I Have an internal table ITAB1 in that i have some 200 records. In that ITAB1 i have
MATNR and MEINS field and iam selecting those fields from MSEG table.
Now my requirment is i have to check for base unit of that particular.
example :
now let us say iam getting in my ITAB1.
MATNR      MEINS
M-123          EA
now i have to check the base material for that material. if both the base unit and what i got i same then its ok.        or    if the both are not same then it should convert to the base unit.
how can i do that.
Regards,
Priyanka.

Hi Priyanka,
To this FM u have to pass the material number, Input unit(itab1-meins), Output unit(Base unit-mara-meins), Quantity. In Importing parameter E_MENGE pass one variable. After FM call u will receive the converted value in this variable.
Just check the where used list of the FM to see the sample code.
    CALL FUNCTION 'MD_CONVERT_MATERIAL_UNIT'
         EXPORTING
              I_MATNR              = P_MATNR
              I_IN_ME              = P_MEEHT "Input unit
              I_OUT_ME             = P_AUSME "Base unit
              I_MENGE              = P_MENGE "Input Quantity
         IMPORTING
              E_MENGE              = I_AUMENGE "Quantity in base unit.
         EXCEPTIONS
              ERROR_IN_APPLICATION = 1
              OTHERS               = 2.

Need PR Unit should not equal to Material Base UOM

Hi All,
I want to maintain Base UOM as 'PC' in material master. Then i want 'BAG' unit should appear while creating PR & PO.
here 1 BAG = 100 PC .
After i maintained 'PC' uom in material master, the uom 'PC' is appearing automatically while creating PR . This field is not editable in PR.
Please advice what i should do so that i can maintain PC as Base unit in material master & i can use unit 'BAG' for PR & PO.
Thanks
pabi

Hi,
Maintain the order unit as BAG in purchasing view of material master.
Maintain conversion factor 1 BAG=100PC in the "Additional Data>>Unit of measure" of material master
Create PR - here, the Unit of Measure will be shown as PC only. You cannot modify that in PR.
Next step, convert PR to PO in ME21N. There system will automatically pick the order unit as BAG and shown in PO item. It will also do quantity conversion to BAG as per conversion factor defined in material master.

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 Ledger Unit Of Measurement different from Material Master

Dear Team,
In my client, there is a difference between unit visible in CKM3N and MM03. The base unit of measurement in MM03 is MT. Other than that, there are some other units maintained (not M3) in additional data tab in material master. In CKM3N, the visible unit is M3. M3 is not present anywhere in MM03.
Why would such unit flow in material ledger table? (CKMLPP has unit M3). Please advise.
One more observation is that when there is some price change document in Material Ledger, the proper UoM (MT) is being captured. Only in the basic price determination structure visible unit for each head is M3. Please check the attached screen shot.
Any help would be appreciated.
Thanks.
Jay Shah.
