the base UoM and process UoM or quantity conversion UoMs are different

[Former Member]

Hi everybody,

during the replication of materials between ERP and C4C in the error log at the web service message monitor i get the following error message:
"Activation is not possible; the base UoM and process UoM or quantity conversion UoMs are different. To resolve this conflict, define a quantity conversion or change the process UoM to match the base UoM."

unfortunately i don't know what "process UoM" means?
what is the different between "base UoM" and "process UoM"

the only thing what i have done is to change the UoM Symbol in the business configuration -> activity -> Quantities and Units of Measure and Code List Mapping from "LT" to "Lt" what i have overtaken in Code List Mapping as you can see in the following screenshots.

In case of Kilogram where i changed the UoM Symbol to "kg" the data transfer would work easily fine and i successfully got some materials into C4C (Codelist mapping: local Code "KGM" with external Code "kg")

Why do i have problems with "Liter"?

Is there anybody who can help me?

Best regards

Gerhard
