Ok, now I understand what you need to do. I don't think you can get this done in the report designer of VA, but you can do this in Prepare data with two Data-queries.
The first query generates the intermediate results (sum of valor and qtde grouped by anomes), the second dataquery uses this intermediate table to generate the final values. If you run the second query, the first query will be automatically run and the output table can be used in the report designer.
To do this, open Data Preparation and select "New dataquery". Select your table and drop it in the middle of the screen. Select the columns you need and change it to look like this (my datasource is BOOK1):

I named this query "IntermediateValues".
After this, create a new Data Query and use "IntermediateValues" as the source for this query. This would look something like this:

If you save and run this query, it will create a dataset with one record (specify the name in the "Outputs" tab on the right side of the screen). This will contains all the values you need.
The query can be scheduled to run every x minutes or whatever to keep the output table updated.
BTW: You can set the labels of the output columns in the "Output Columns" tab at the bottom of the screen.
BTW2: To get the fields in the order you have specified in your attachment, check the aggregate functions in the order MAX,AVG,MIN. This will result in MIN,AVG,MAX
