Thanks for your reply . Can i ask more question ? In my case , the TransactionItem is the files path or value from each row in Excel file . Because i will extract data from PDF Files and Extract data from Excel file , then i will compare its together .

This one you can do it in the Process Transaction and also compare the data there.

In the Get Transaction you can just get the data from the excel one by one based on the Design of your project

It’s mean i must change the data type of variable TransactionItem to DataRow ?

in that case you TransactionItem type would be string and TransactionData would be list of string.

Your mean is TransactionItem will be files path (string) and TransactionData is files path stored to array (list of string) ?
