Hi,

I was trying to change the column name in the DataTable from Debit(Withdrawal) to Debit using the Assign - Change Name step:

To: ItemDT.Columns(“Debit(Withdrawal)”).ColumnName
Value: “Debit”

I get the following error:

Assign - Change Column Name: Cannot create an L-value from the given expression with property ‘ColumnName’ because the target object is null.

Please let me know what the issue is.

Thanks!
