DTP cannot be activated; transport/activate chain again

What causes this issue?

You want to execute the data transfer process (DTP)&v1& within a process
chain.

System Response

This is not possible at the moment.

How to fix this error?

The DTP&v1& is not available as an active or a revised version. This can
be due to the following reasons:
You copied the process chain from the BI content. The DTP&v1& was not
copied correctly from the shadow version to the pseudo-D version or the
active version.
<DS:TRAN.RSOR>Copy the process chain again from the BI content.</>
Make sure that the Match (X) or Copy indicator is not selected.
You transported a process chain as active version. In this case, too,
the transported version of the DTP could not be copied to the active
version.
Transport the process chain again and analyze the transport log.
