  TS:

  
  
  var ng = this.thePivotPanel.engine
  ng.rowFields.push('Country');
  ng.valueFields.push('CQ_WK1');
  
  

  if I don’t add the above two line then no error but grid is not loaded as there is no rofields and values fields
  
  HTML

  
  <div class="mdl-cell mdl-cell--4-col">
                  <wj-pivot-panel
                          #thePanel
                          [itemsSource]="rawData">
                  </wj-pivot-panel>
              </div>
              <div class="mdl-cell mdl-cell--8-col">
                  <wj-pivot-grid
                          #pivotGrid
                          [itemsSource]="thePivotPanel"
                          [showSelectedHeaders]="'All'">
                  </wj-pivot-grid>
              </div>

  It looks like one of the fields with the specified name(‘Country’ or ‘CQ_WK1’) doesn’t exist on PivotEngine(ng instance).
  
  Please make sure that the fields with the specified name exists.

  let downloadsField = ng.fields.getField('Downloads');
      if(downloadsField){
        // downloads field exists, push to the collection
        ng.valueFields.push(downloadsField);
      }
  

  If you are still facing issue then please modify the following sample so that it replicates the issue:
