Hi Manuel

You could use GQI to fetch these indices using the built-in ‘Get parameter table by ID’ data source. This data source has 2 inputs: DMA ID & Element ID. When selecting a row from the query result, an ‘Indices’ data item should be available.

Update

since the ids need to be dynamic, an ad hoc source will be the way to go. You can add metadata to the rows returned for an ad hoc source. This will make the rows have an ‘indices’ data item that can be used as data/filter in the components.

var param = new ParamID(DataMinerID, ElementID, ParameterID, Index);
var paramMetadata = new ObjectRefMetadata { Object = param };
var rowMetadata = new GenIfRowMetadata(new[] { paramMetadata });

var row = new GQIRow(…) { Metadata = rowMetadata }
