Change the query used for queryFeatures to only fetch the features you are interested in.

Hi,

Thanks for the reply. Sample code seems to be copy entire feature from temp layer to master layer. I need to copy only few features not entire feature. Kindly let me know how to do it?

I did something like in this blog post.

Here is a codepen.

It's something like this.

function copyLayer(lyr, title) {
    const tempLayer = new FeatureLayer({
        title,
        fields: lyr.fields.map(x => x.clone()),
        geometryType: lyr.geometryType,
        renderer: lyr.renderer.clone(),
        spatialReference: lyr.spatialReference.clone(),
        source: [],
        visible: false
    });
    return tempLayer;
}

// later, might need a where: 1=1 query
const { features } = await soureLayer.queryFeatures();
const result = await localLayer.applyEdits({
    addFeatures: features
})
.catch(err => console.log(error));
localLayer.refresh();
