Diagnosis
You have selected the Table Cluster &V1& to be put on the SPUMGException List. Putting a Table Cluster on the Exception List makessense only if the corresponding Cluster Tables are put on the ExceptionList also.
Background: A Table Cluster stores data of several Cluster Tablessharing a common key. If a Table Cluster is put on the Exception Listwithout the corresponding Cluster Tables, it is possible that the commonkey is converted differently for the Table Cluster and the ClusterTables thus leading to inconsistencies during the Unicode conversion.Therefore it is recommended to put the tables (Table Cluster andcorresponding Cluster Tables) together on the SPUMG Exception List withthe same settings (Fallback Codepage, Character Set for all entries).

Procedure
If you want to put the Cluster Tables belonging to &V1& on the ExceptionList also you can
Go to transaction SE11 and build the "Where-used-list" for the TableCluster &V1&
Enter the name of the Table Cluster in the "Database Table" selection
Create the "Where-used-list (CTRL-SHIFT-F3)" for &V1& (Used in "Tables"only) to get the corresponding Cluster Tables of &v1&
Use the result to select the Cluster Tables in the SPUMG worklist andput the tables on the Exception List with the same settings as it wasdone before for the Table Cluster &V1&
