In Internet Services, errors occurred during conversion

What causes this issue?

The cause of the error cannot be determined exactly.
A service in the old format may exist, for which in the new format no
entries for the service itself but entries for subobjects exist. This
may happen when transports with subobjects have been imported into the
system, but not the service itself.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The errors need not be corrected during the upgrade.
If you do not use an ITS (Internet Transaction Server), the productive
operation is not hindered. Productive operation is not hindered either
as long as you only use standalone ITS installations. Only as of Basis
release 6.40 the ITS is available as part of the application server, so
all installations up to that release are always standalone ITS
installations.
A check and, if necessary, error correction is necessary only before you
use the ITS as part of the application server with one of the defective
services or before you publish or further develop one of the defective
Internet services.
Error Analysis and Correction:
The messages below (expand the log further) inform you about the
services concerned. On development systems, you can use transaction
SIAC1 to display an overview of the services in the old format and try
to convert them into the new format. Note that you can ignore all
objects that still exist in the old format unless they belong to one of
the services explicitly marked as defective or to your own developments.
The report SIAC_XPRA_CONVERT_FROM_4X_70 can be started again after the
upgrade. However, after a complete run no changes are to be expected.
