Capacity planning in kilogram


we have a business unit that would like to do their capacity planning in kilogram, and I cannot seem to get it to work. I have created a standard value parameter with the dimension of MASS and unit KG.

This is then put into a standard value key.

I have also created a new capacity catagory with capacity type 1 'Available capacity defined in volume unit and unit of measure'. But when I try to enter this capacity catagory in the work center it gives me this error 'Capacities of type 1 and 2 are only allowed for ressources'

Can anybody help me? What am I doing wrong?

    In SAP Standard Capacity Planning , any PP Master data like Work Centre will have Avaliable Capacity in Time Unit Of measure .

    like Min , Hr , Days etc but never in KG/Liter because Work Centre Capacity means how much hrs /min /days etc , this particular work centre will be available to execute a series of operations in routing or a single operation in routing so on so forth .Any operation in the routing either will be having three kind of time : Setup time , Machine Time , Labour time which are basically will be calauted based on the Standrad Value key and Formula key .

    This Standrad values are also related to costing in Work Centre-Costing view base on thr Time involved in each job not in terms of KG unit of meauser .

    So , i do not think it is recomeded to utilise KG as Capacity for any work centre to carry out Capacity Requirement Planning as it has lot of implication in Planned Order /Production operation dispatch , scheduling , costing etc.Specially , if you are particualr in CRP for detail scheduling of Production order , then KG will not work rather scheduling happnes based on available capacity of work centre in date , Time and work centre load with certain SAP Standrade set up

    Hope it is clear and wait for experts to comment on the same

    Hi LJU,

    1. Yes you will be able to enter capacitycategory with Time unit of measure only.

    2. In case if you need to do capacity evaluation in the diferent unit of measure try this.


    3. Go to the header capity view.

    4. Go to the Extras

    5. Unit of measurement

    6. Now you wil have the Conversion of units os measurement

    here you can maintain the conversion like 1 Hr = 10 kg ( ex)

    let me know if this helps.

    Hi Dsk,

    thank you very much for your answer. We know about the conversion rules for the unit of measure, but this is not really what the business unit wants.

    I thought, that since you are able to create a standard value in unit of measure KG, it should also be possible somehow to do capacity planning on it.

    But you are saying that capacity planning can only be carried out in time units?

    thank you very much for your answers.

    I see what you mean, but I think my 'missing link' is why SAP is allowing you to create a parameter in KG, use it in a formular, beeing able to use this formula on the capacity tab in the work center...but maybe this is just yet another feature of SAP that you have to live with 😊

    Again, thank you very much for you answers.

      A parameter can be created in KG or any other unit of measure ; it can be used in any formula for capacity or costs purposes but not as the final "capacity" of the work center but as some intermediate result that allows a more precise capacity calculation.

      Assume that you have different throughput in a work center depending on the temperature. You can have a parameter in °C (temp), then another in production rate (kg/H) which depends on the first parameter and finally the Capacity requirement in the work center is calculated as the order quantity (KG) divided by the production rate. You have finally Hours as capacity, but two parameters have been created with different unit of measure just for the sake of a more precise capacity calculation.
