How To Fix UMG411 - Unicode Conversion tables might contain corrupted entries (see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: UMG - Message Class for the Unicode Migration Tool.

• Message number: 411

• Message text: Unicode Conversion tables might contain corrupted entries (see long text)

What causes this issue?

You execute transaction SPUMG for the preparation of a Unicode
conversion. According to SPUMGs status tables you execute SPUMG for the
first time in that system.
During startup of SPUMG a check was executed which found data in some of
the Unicode conversion control tables. In general this must not happen
if SPUMG is started for the first time. To avoid possible data
corruption during Unicode conversion you should read through this
message and decide whether to reset SPUMG or not.

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

Possible reasons for the existing records are:
You started SPUMG some time ago or long time ago on a low support
package level and imported new basis support packages meanwhile. It is
now possible that the new check found old or outdated information in the
Unicode conversion control tables.
Data have been transferred from other systems, e.g. by transport request
or by a so called TWIN transport.
In general the preparation for a Unicode conversion needs to be done in
each system individually. Data must not be taken over from other
systems.
In case of a TWIN procedure: the TWIN system has to be on the same SP
levels (basis and application) as the original system in which the data
are taken over. Otherwise inconsistencies might occur in the original
system after data have been taken over.
Data have been delivered by support package or have been imported during
system installation.

System Response

How to fix this error?

After confirmation of this message you will be asked for the deletion of
the Unicode conversion control tables.
If you agree, SPUMG will be reset and the preparation for the Unicode
conversion can be started from scratch.
If you don't agree you can continue with the first steps of the Unicode
conversion preparation. When proceeding with SPUMG you should check in
detail that there are not out dated data stored in the Unicode
conversion control tables, e.g. the Export Control Table, the SPUMG
Language List and the SPUMG work lists.
