Re: can anyone tell me the flow of execution in the below case
You create 'A' inline table (with manual entry of information) with 'A', 'B' and 'C' as dimension fields and 'Sum' as an expression field.
You create 'B' table from resident table 'A' with dimension fields 'A' and 'B' and an aggregated expresion field 'total' result of the sum of 'Sum' expression field. This aggregation is made from 'A' and 'B' fields.
You drop 'A' table as it is not needed furthermore.
