dear @Sneha11
you are missing something to bind.
check each and every workflow arguments binding.
and then before in_transactionNumber <= dt_WorkItems.count you should you an write line activity to check the value of dt_Workitems and transaction number.

[Sneha11 (Sneha)]

how can I write this activity please tell me and give me this screenshot.

[Muhammad_Jahangir]

use write line activity and pass transaction number. and in another write line use datatable.rows.count.tostring
it’s for checking that data from previous workflow is coming or not.

@nadim.warsi! How are you? I have been trying this and needing help. I believe your solution will work. Trying to understand what #2 means. Attached are the workflows. Kindly change the xaml.

Appreciate it!

@nadim.warsi! Please ignore. It was resolved using your three steps above. Thanks much!
