& temporary time series found

What causes this issue?

Temporary aggregates were found when the objects relevant to the
download were determined in liveCache. These objects are created during
the planning processes in Demand Planning to enable you to work with
planning data on an aggregated level. In most cases, the temporary
aggregates are removed at the end of the process or via the consistency
checks in section A.
If the consistency checks are not performed or if planning processes are
terminated between section A and section B, any temporary aggregates
created as a result of this are identified at the time of the download
and are entered in the log with a warning.

System Response

The existence of temporary aggregates is logged. Any temporary
aggregates that are found are extracted from the liveCache just like all
other time series.

How to fix this error?

You can continue with the upgrade or download/upload process. However,
note that superfluous objects are processed in this case. This can
significantly influence the runtime of the subsequent steps in section
C.
In the target system, you can assume that the consistency checks named
for Demand Planning in section A will find inconsistencies after the
upgrade.
