Hi,
It seems the problem has not fixed yet.

As workaround, can you try to replace the Assign with MultipleAssign as the following?

Hi @vignesh_S.M,

The workaround using Multiple Assign can work, but you can also try this solution :

keep out_TransactionItem as Object, assign Nothing, and cast it to DataRow only where it is used in Process.xaml.
