Hi Shubham,

I agree with others, you can create an internal CDT (not mapped to any table) with the required fields.

Create an expression rule and map you required data using two variables - one retrieving the data (a and b) and the other retrieving the aggregate data (Total a, Total b).

Then map your required data in the internal CDT with a!forEach()

In the interface map a local variable with the Expression Rule and use this local variable as data in grid.

Regards,

Farnaz

puh, this goes deep and needs a lot of explaination.
you need a query rule regarding aggregation:
see here:

https://docs.appian.com/suite/help/21.4/fnc_system_a_query.html

https://docs.appian.com/suite/help/21.4/fnc_system_a_queryaggregationcolumn.html

second: you need to fill your grid with the suitable query result.

Okay, But how to insert Total after each set of rows. If possible could you please explain more and share the code snippet, it would be really helpful.

Create a rule using Query Aggregation to get the count of each column. Then use the rule as data source for readonly grid
