Many Thanks

Hi @dany08

Type row(“Type”).toString.Equals(“WI4”)

check your variable TransactionItem is assigned or not!
in import arguments section!

dt_WorkItems is null. Please check the above screenshot in the Locals pane.
Looks like you have missed mapping the arguments from the calling workflow. From the file where processyearlyreport is invoked please go to Import arguments and pass the correct parameters to the arguments.

Same error with this modification

Your Dt_WorkItem is not imported into Processyearlyreport.xaml file. so when this workflow is called your datatable variable is null as it not assign or initialize.

yes already assigned
