Hallo
I got a problem with the units in the composition of specifications.
When I try to create a new composition I get the following message:
UoM % does not correspond to the dimension of the selected value assgmt
I figured out that the dimension (PROPOR) where the reference quantities (W/W, VOL/VOL) are assigned to is missing in my system. I tried to create the dimension with the IMG "Check Units of Measurement" but I'm not sure which settings to thake to make the whole thing work. Could anyone please give me some advice how to setup the dimensions and the UoM.
Thanks
Kind Regards

Hello Gerhard
you are using the right Customizing activity. Normally EH&S related UOMs should
be there (after standard SAP set up and after EHS activation) including PROPOR
etc.
Pay attention on this: PROPOR is used for UOMs which do not have a "unit" like
"part per part". W/W should not be related to PROPOR because the physical
meaning is "mass per mass"; same as with VOL/VOL (volume per volume). In
standard SAP as well as EH&S setup normally you generate a number of "PROPOR's".
UOM definition is one of the critical topics in EH&S (pay attention in WWI topics; UOMs are quite "strange" in WWI; refer to some threads in this FORUM describing problems here)
One "PROPOR "is defined as "part per part" one regarding "mass per mass "(I believe most common is: WPROPO) one
regaridng "Vol/Vol (e.g. VPROPOr") etc. Now you must relate the corresponding
UOms to these values. Many companies do not use the "simple" "percent" but call it
(which is more correct) it "w percent" or "V percent"
The use of UOMs in EH&S is critical not only in the area of compositions but
characteristics too. Some characteristics are defined like: "Values in standard
unit percent" Keep in mind that normally that here "mass" is the "correct" related
UOM. If you do it wrong with UOM definition you can "crash" EH&S (and any other
SAP module) because the UOMs are used globally in any SAP module. So pay
attention on the definition of UOms related to your classes/characteristics
(either SAP original one or customer specific one) you are using in EH&S.
Please take some care in linking the "reference quantity" of the composition
together with the "UoM" of a "line" (one component). On the top: if you use the
WPROPO approach you must (should) define subsequent UOMs like
m percent etc.) etc. etc. and what is important you must make sure
that you "translate "the UOms (so that you can print something in WWI reports)
So before you start this customizing acitvit you must be familier with the
standard SAP setup on and you must understand the "pros" and "cons" of using the
PROPOR later in EH&S
With best regards
C.B.

Hello Mr. Bergemann
thank you really much for the answer.
I finally found the default settings of the SAP EH&S in the Client 000. There is a transaction (SCU0) where you can transfer customizing settings between systems and clients. You have to choose the application component BC-SRV-ASF-UOM.
But it is in this case really important in which language you are logged in when you change the settings of the UoM. In the first place you have to set the UoMs and the dimensions with the logg-in in english. After you created everything you can change to your "normal" language e.g. DE and change the text as you like.
So my settings are:
Dimension PROPOR
Important: Luminosity hast to be 10
UoMs relating to the dimension PROPOR
1 ONE (this one is really important it has to be the int. meas. unit 1)
% percent
%0 promille
ppb parts per billion
ppm parts per million
ppt parts per trillion
after you created the UoMs and assigned it to the dimension you have to declare the SI-Unit for this dimension.
For PROPOR it has to be the 1 ONE UoM.
There are two other Dimensions as decribed by Mr. Bergemann. MPROPOR and VPROPOR.
You can find the default settings in the client 000 of your SAP System.
