Hi @shivarajvp555 ,
Are you looking for a Specific value to use as a Look Up Value ? Or do you want to iterate through all rows of DT1 and use the concat column value as Look Up value in DT2 and fetch the corresponding row from DT2 and get the address ?
If you could provide us in the form of what are the Inputs and what should be the output, we would be able to help you faster.
