Met problem to change unit of measure in material master

Our prime made mistake when creating material master with MM01. He used wrong unit of measure EA instead of right one M. And when he recognized this issue and tried to change it with MM02 in view Basic1, system prompt him an error message that "Standard cost estimates for the current period already exist".
So, please help to let me know how can I delete related records about cost estimates and avoid this error. Thanks a lot.

Robbie,
You can delete Cost estimates using T-code:  CKR1 , I am not sure if you can change UoM if you have any goods movements  on the material. The best option would be create new material with correct UoM and transfer stock from old Material to New one with proper Conversion.
Thanks

  • Update info record when changing units of measure in material master

    Hello,
    is there any possibility for an automatic change of info record when changing conversion factors in the material master ?
    We have 3 units of measure in our material master: the base unit and 2 alternative units. The first alternative unit is the order unit and the second alternative unit is the order price unit. So in our purchase info records we maintain an order unit, which differs from the base unit and we also maintain an order price unit, which differs from the base unit and the order unit.
    If we now change the conversion factors between the units in the material master, we would like to get an automatic change of the converions in the info record (to order unit and order price unit), which have the same previous conversions.
    For IS R it seems to be implemented (see OSS-Note 975954).
    Is there any solution for a "normal" industry system ?
    Thanks for answering

    I don't think such an auto update is available. Infact I came to know that such an update is available in IS-R after reading your query.
    Obviously you an always create a workflow based enhancement that can synchronize the Info-records and material master changes or sort of enhancement which regularly reads the material master change history for such changes and trigger a synchronization by executing change Info-record automatically.

  • Changing the Unit of Measurement in Material Master

    Dear Experts,
       Material DF21DENG (fert) was created with KGS (kilogram per second) as its unit of measurement. A material BOM was now created for DF21DENG.
      I intend to change the unit of DF21DENG from KGS to KG (kilogram).  On doing this in the Basic data view of DF21DENG, i get the message " change is not possible because a BOM exists for this material".
      In the BOM of DF21DENG, I set the deletion flag on & tried to change the unit in the Material master again but got the same massage.
      Please how can I effect this change?

    This response was helpful but was solved the problem was that; from the Edit, i  selected Delete  from the drop down & then the alternative BOM was deleted.

  • 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.

  • Error when changing unit of Issue in material master

    Hi,
    When i am  trying to change Unit of issue in Qualitymanagement view of  a material using MM02 transaction, we  got error message - "The unit of issue cannot be changed because the material is used in a BOM-------Mesage no. M3214"
    Can anyone suggest what is the reason behind this. ?. how to avoid this error.
    Thanks in advance.

    HI Aditya,
    "The unit of issue cannot be changed because the material is used in a BOM-------Mesage no. M3214"
    The reason is that material is used as a component in BOMs with the present unit of issue as a unit in the bom line item.Unless you change that bom line item unit to its base unit ,system will not allow you to change the unit of issue in QM.
    First check in which BOMs the material you were changing is used as a component.this you can do in transaction CS15.
    then change the unit of measure used for the material in bom line item to base unit of measure.if one only one BOM is there change in CS02.if more BOMS are there do mass change in CS20.
    Then try to change the unit o fissue.now system will allow you to do the changes.

  • Unit of measure in Material Master after PO's created

    Hello Everyone,
    I know that we can't change the material measure unit once PO's and other documents are created.
    What can I do with the PO so i can change the material measure unit?
    Thanks in Advance.

    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.

  • Error while defining alt unit of measurement in material master

    All SAP gurus,
    i am trying to define a alt unit of measurement in a finished material, the base unit of measurement is in MT, and the sales unit is nos. the conversion formula is 53 nos = 1kg i.e. 1MT = 53000 nos. as conversion can be done only with base unit of measurement i am giving 53000 nos = 1 MT, but system unable to calculate the conversion as it is not taking mere than 3 digit after decimal.
    e.g.    if 53000 nos = 1 MT
    then  1 nos should be = 0.000018 MT
    but system not taking this value as this value contain 6 digit after decimal
    suggest me what can be the way out? with detailed steps. can i increase the post decimal value or i have to define another middle alt unit of measurement (like KG). and if that is to be done then how.
    Regards
    BKR

    Hi,
    With help of Basis team check the decimal places for u r user ID.

  • Unit of Measurement in Material Master

    Hello Experts...
    I have an intresting issue on Unit of Measurement. I would like to maintain alternative unit of measurement as per below..
    1 EA = 1 EA
    1 ROLL = 5000 EA
    1 CT = 150,000 EA
    However the field UMREZ length in the material master allows me to enter upto 5 digits...and also it is not possible to enter decimal digits here.
    Have any one of you faced this kind of issue, if any one faced what would be the solution for this...?
    Look forward to hearing from you..
    Cheers
    Umakanth..

    Hi Umakanth,
    For increasing the numerator for conversion of base unit of measure, UMREZ  would be  appending the structure SMEINH by requesting Access Key from SAP.
    Even though its not a suggestible decision to append standard SAP structure , if the requirement demands we may need to do that.
    Cheers!

  • Unit of Measure in material master

    Hi
    I have a Raw material consider (Forging) for which material master is maintained  "PC"  as Base unit of Measure. I have defined in Additional Unit of Measure as 500 KG = 1 PC. Also my order unit is also maintained as PC.
    Here when they procure castings they order it as 1 PC only. But when the actual material comes there may be some variation in weight.  The client wants to make payment on actual weight basis only .
    Also stock keeping unit and issue of material is done as PC only.
    Please guide me how to address this issue.
    Regards
    Kumar.

    Hi
    With the existing master data you can acheive your requirement.You can maintain the price in info record in Kgs or in PO Item conditions tab you can maintain the price per kg.
    while doing the miro please enter the actual quantity in<b> Qty in PO price unit</b> in Quantity tab ans save the GR.When you do MIRO, system will propose Qty as 1PC and value as <b>Qty in PO price unit X Price per kg</b> maintained in PO.Please try this solution.

  • Prevent change unit of measure on a component in an order

    Hello,
    Is it possible to prevent the user to change the unit of measure (UM) in the component of an order.
    What I need is the unit of measure from the material master without the possibility to change it.
    Thanks,
    François

    thyagarajan,
    By default, the system displays the Unit of issue entered in the material master. If none exists, SAP display the Base Unit of Measure.
    The problem we're facing is when many units exists in the material master.
    Example: "EA" Each and "DZ" Dozen is defined in the Mat. Master, with obviously defined as 1 dozen equals 12 each.
    If a user enters 1 "EA" in the ORDER but the Unit of issue is in DZ, the Procurement side will see that they need to buy 0,08 DZ wich is impossible because material is sold by dozens...
    We need to prevent the usage of smaller unit equivalent on the order side.
    What do you suggest?
    François

    Hi,
    You can change UOM only
    1.No stocks are  available for the material.
    2.no existing PR,POs or scheduling agreements for the material. And material is not  link to BOM .
    For more clarity please refer the below links.

  • Alternate unit of measure for service master

    Dear all
    I have same service but different unit of measure like hr, day, month, pls explain how make alternative unit of measure in service master?

    Hello,
    I am afraid I must confirm that the system is working in this way...                                                               
    It is not possible to define an alternative unit of measure in the service master in R/3.                                                    
    If you want to create a purchase order with another unit of measure, you have to create a seperate service master with this unit of measure.   
    Thanx & Sorry
