How to get compare the datatable with another datatable,if the value specific value is not available

The main mistake in your flow is, inside For Each Loop you should have the dtTemp. That is the main filter.

dtTemp = dtAllCountry.AsEnumerable.Where(Function(r) r(“Country”).ToString.Trim.ToUpper = row(“Country”).ToString.Trim.ToUpper).CopyToDataTable

After this Add Data Row.

I’m not able to attach the workflow here. So created the new post.
