Ref and in transaction number

Hi guys,
i’ve a question, i’m implementing the process with REF and in transaction item as data row, my question is: where i need to initialize in transaction number with 0(my datatable index?)
Could i do directly from the Arguments tab? Thanks


Open Main.xaml file and look for TransactionNumber variable. By default it is initialised with 1 in REframework and change it to 0.
