what is "through xml"?

xml just define the view, how it can help?

Hey Muhsin,

there is no way removing duplicates via XML explicitly.

You are only able to filter the items but unfortunately not with something that removes duplicates.

Depending on your model (JSON or OData) you can remove duplicates in your Backend Service (OData) or remove them before setting the data to your Model (JSON)

Hope that helps.

Hi Muhsin Panakkal,

if you are using odata service, this is design issue, sometimes you wont get duplicate record with test run, but after binding you gets duplicate due to design issue,

in the entity set there is no proper unique key assigned, check the properties of entityset and set the unique key(s) there itself. duplicate value will be avoided.

var arr = [{ "State": "RWCW"}, { "State": "RSCW"}, { "State": "RWCW"}, { "State": "RSCW"}]; var clean = arr.filter((arr, index, self) => index === self.findIndex((t) => (t.save === arr.save && t.State === arr.State))) console.log(clean);
