Hi Luiz,

I have two tables[transactions table and Header table] and merging them make one table [Grand Table] , along with that I need to add few more column with few logic's. For one column to add I need this Function to use, the inputs of this function are columns from Table Transactions and Header.

I have stuck here to add these columns because the inputs for this functions are columns from other tables. Can you give any ideas.

Many Thanks
