What logic sap uses when choosing "volume unit" for a material (mm01/mm02 Basic data)

Hello friends,

do you know what logic sap uses when automatically choosing "volume unit" for a material? (in mm01, Tab basic data 1). Can there be any units of measurement that sap automatically uses or on what these units of measurement depend on?

The situation is as follows:

usually we do not maintain volume and volume unit manually. We just enter length, width and height plus unit for those. The system calculates volume and volume unit automatically.

I created two examples in test system:
example 1:
I created material via MM01 and maintained length, width and height directly during that. Result is a volume unit CDM (for material with industry sector M - "Mechanical engineering" and material type "BAU" - Assembly).
example 2:
for analog material, but I created material via MM01 w/o length, width and height and maintained those via MM02 in a second step. Result is a volume unit in HL (!).

Is there a logic on part of SAP? Do we have a chance to get CCM, CDM or M3 in all cases instead of L or HL (which should be used for liquids)?

Thank you very much!

    hi annet,

    In material master, above basic data 1 view you will find Additional data tab.

    here you can see when you enter the parameters like Height,width, length the system as per base unit of measure calculates the volume of that material,

    So when you choose your volume unit( cubic inch, cubic foot,liter, gallon etc.) system calculate

    according to std mathematical formulas


    Volume of cube = Height x Width x Length i.e (a power 3)
