• Message class: RSAR - Data Transfer and Metadata Maintenance

• Message number: 399

• Message text: Source system &1 is a dummy. Object not executable

What causes this issue?

The source system &V1& is only a dummy for the source system &V2&. It
can only be used for modeling source-system-dependent scenarios. The
loading of data is very restricted:
Full loading processes can only be performed under the following
conditions:
The structures of the DataSource in the original source system &V2& and
the source system dummy &V1& are identical.
The DataSource is active in the dummy and the original system.
The DataSource has the the same object type (RSDS or ISFS) in the
original and the dummy.
Data can be updated using a data transfer process from the PSA of the
dummy.
Init and delta loading processes cannot be performed due to the
following reasons:
It is not possible to load different selection conditions in the
original and dummy systems. The original system is always used for
loading and it only has one init selection.
Deltas can only be sent to a BW once. Therefore the same delta cannot be
loaded from the original system and the dummy system.
