Message text: For table &1 "Sum" chosen as duplicate handling. No fields to sum up.
For table &V1& "Sum all CURR and QUAN fields" was chosen as the type of
duplicate processing . However, the table contains  no fields to be
summed up (of type 'CURR' or 'QUAN').
Status is set to 'Error'.
Configure the duplicate processing method correctly.
If 'Ignore duplicate entries' is not the desired method of duplicate
handling analyze the table and its contents to find out which method is
suitable for conversion of this table.
If you want to aggregate some fields of the table (also sum them up if
their type is numeric but neither 'QUAN' nor 'CURR') then you should use
duplicate processing with 'Aggregate routine' in combination with an
appropriate aggregate value for all fields you want to aggregate.
If you want to have full flexibility of deciding which entry should
remain in the database in case of duplicates you should choose 'Priority
routine' duplicate handling and define appropriate priority routine.
'Priority handling' also allows chosen fields to be aggregated.
