I think you don't need the "Sales" column. Also you don't need individual columns for each Quarter. You can arrange your data under the following Dimensions:
Product Type (A, B, C,D)
Type (this would have values Actual, Target and Forecast)
Quarter (this would have values Q1, Q2, Q3, Q4)
And a single Measure:
Sales (this will contain the values, irrespective of Actual, Target and Forecast)
Then you can easily create the view you are looking for.
