Message number: 042
Message text: Differences regarding cost element categories found, merge not possible
The participating cost elements have different categories. Cost Elements
with different categories cannot be merged.
You cannot run the transformation solution because certain prerequisites
have not been met.
To resolve this error, the mapping needs to be adjusted so that these
cost elements are no longer merged.
This error can also occur if cost elements are merged implicitly
(because the corresponding controlling areas are merged). Example: Cost
element 610100 in controlling area DE01 uses type 01, while cost element
610100 in controlling area US01 uses type 31. To resolve the error, the
cost elements must be given different names. However the functionality
for renaming cost elements that have the same name before the conversion
to different names after the conversion is not part of the
transformation solution for controlling area merge. To rename cost
elements in this way, you have to do a chart of account conversion.
Note that this issue may also occur with secondary cost elements.
<ZH>Note</>
In order to proceed to the next phase, all checks must have the status
Green or Yellow. If you consider an error to be acceptable (for example,
if you know that it does not affect the consistency of the conversion),
you can change the status of the check from Red to Green by confirming
it.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
