Calculate Client Security Hash - Extracted DT shows Null in GetTransactionData workflow

i got it what is issue you faced

for my scenario I call Extract_workItem Workflow in init section instead of under initapplication workflow

for your case you need one more assign action

  1. initApplication to init where you invoke InitApplication > then InitApplication to Init

i attached my Main.xaml (57.5 KB)

hope its help you

Thanks
