What causes this issue?

The check "Inactive Nametabs UC" looks for table entries in table
DDXTT_CONV_UC. The table is the so called "inactive alternate nametab".
In general this table is empty. A non empty table DDXTT_CONV_UC
indicates that nametabs have been generated not correctly. This can have
an impact on the consistency of the system after the Unicode conversion
because of the nametab switch during Unicode conversion.
Please read note 932779 for more information on the handling of nametabs
in the Unicode conversion.

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?

Before the Unicode conversion you have to delete all the entries from
the table DDXTT_CONV_UC.
