hope this expression would help you resolve this
dt = dt.Asenumerable().Groupby(Function(a) a.Field(of string)(“RUN ID”).ToString).Select(Function(b) b.First()).Copytodatatable()
where dt is your datatable
and if you are not getting asenumerable then kindly have a view on this
Check this component,
may i know at which activity we are getting this
is the RUN ID column is of type string
if so kindly remove that .ToString in the expression and try once
if not kindly share the xaml if possible
This activity working.
