BRF+: Object changed after write to transport; see long text (SE91)

What causes this issue?

The current BRFplus content object has been changed after it was written
to the transport request.
Whenever a BRFplus object is changed, it needs to be written to a
transport request in order to make sure that the transport piece list
reflects the latest version of the object. Normally, BRFplus performs an
automatic change recording to make sure that this requirement is
fulfilled. However, for the current object, this mechanism has failed
and the object status recorded in the transport request is not
up-to-date.

System Response

The object needs to be written to the transport again before you can
release the transport.

How to fix this error?

To write the affected objects to the transport request again, start
report <DS:REPN.FDT_TRANS_MASS_CHECK>FDT_TRANS_MASS_CHECK</> with a
selection for the transport and the following settings:
Table Type Selection:
S-Tables (X)
