Insert subtotals in WEBI from bex Structures

Hi all,

I  am trying to  create a report for costs and production that will be reflected in a same measure, as actuals and budget and all this needs to be by department and by plant. I created 2 queries one containing the costs by department and the other one the production volumes. I was able to merge all the information in a single table and joined the measure with a variable however the next challenge is to insert a subtotal in the strucutre. I am not been able to do this as the strucutre can not be broken, any ideas on how to get this?

Here´s an example of what I want to achieve

Plant A

Production

Actual               Budget          Dept

100                    100               Labor

100                    80                 Material

200                    180               Subtotal

250                     200              Dissolution               (Production Volume)

50                         20               Total

Where Labor and Material are in 1 query and Disssolution in second query

Thanks and regards!!
