AX – D365FO – Get current data source record

If you want to get the current selected data source record you can use dataSource_ds.cursor() method

See code below

public void executeQuery()
{
      super();
      if(Al0VendorActivity_ds.cursor().RecId != 0)
            {
             QueryBuildDataSource productCategory_ds =       this.query().dataSourceTable(tableNum(Al0VendorSearchCriteria));
             productCategory_ds.addRange(FieldNum(Al0VendorSearchCriteria, VendorActivityRefRecId)).value(int642Str(Al0VendorActivity_ds.cursor().RecId));
            }
}
