i am getting exception in these workflow
please help me in this error

Hi @Manisha541,

Checked the workflow, you need to increment “CurrentRowIndex” this variable inside the for each.
Else if you need to get the index of your dtReport row then use dtReport.Rows.IndexOf(row).

In which activity you are getting error, just try once by doing the above steps and debug.

@sarathi125 i am getting error in the assign activity
and i have incremented currentrowindex but it is getting same error
