How To Fix UMG373 - The language "?" cannot be inserted into the SPUMG Language List.

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 373

• Message text: The language "?" cannot be inserted into the SPUMG Language List.

What causes this issue?

The SPUMG scan "Tables with Ambiguous Language Information" found
records which use the character '?' as language key. You tried to assign
a code page to the language by inserting it into the SPUMG Language
List.
But the language '?' cannot be used in the Language List because it is
used in the SPUMG vocabulary to mark words for which the language is not
known. Therefore no code page assignment must be done for language '?'.

System Response

All other languages you marked in the "Invalid Language List" have been
inserted into the Language List.

How to fix this error?

You can insert the language '?' into the "Ambiguous Language List" and
repeat the scan "Tables with Ambiguous Language Information" for the
affected tables. Then all the words using the language '?' will be
inserted into the system vocabulary.
You can also continue without repeating the Ambiguous Language Scan. The
scan Reprocess will find all the records using language '?'. The records
will be inserted into the "Reprocess Log". In the Reprocess Log a
language can be assigned to the records.
In general only very few records are affected. Therefore it does make
sense to continue the preparation without repeating the scan Tables with
Ambiguous Language Information.
