How to get Data from RecordData ?

Question

Hi, I have a recordData used to display a simple grid. How may I take advantage of the local!data var ? I woud need to get the TotalCount of this RecordData for example, or to copy data in a CDT list. Have I to cast this variable ? 
 local!data: a!recordData(
 recordType: 'recordType!TT_R_Vehicles',
 filters: a!queryLogicalExpression(
 operator: "AND",
 filters: {
 a!queryFilter(
 field: 'recordType!TT_R_Vehicles.fields.model',
 operator: "=",
 value: "BMW"
 )
 },
 ignoreFiltersWithEmptyValues: true
 )
 ), 
 
 a!gridField(
 label: local!labels.units,
 labelPosition: "ABOVE",
 data: local!data,
 columns: {

If you want to use the a!queryRecordType() to query record data and also want to utilize record features like user filters, search record or Export excel then there is absolutely no way around and you only have to query the record type twice for fetching the totalCount using a!queryRecordType() and for gridField() data using a!recordData(). The only possible way but not at all feasible in this case is to manually create OOTB record features functionality using SAIL design components and smart services but instead of putting all this huge amount of extra effort simply querying the recordType twice is more suitable.

a!recordData() is only for defining data from a record type within certain components, to query data you want to you a!queryRecortType()
