previos month value in Crystal Report

Hello

I have got a crystal report looking as follow

Grouplevel                             Revenue | Margin
GH1 Country        
GH2 Customer (drill)

The user selects a specific month as parameter.

So I now want to ad a column showing the revenue of last month.
I already managed to get this partially work, using shared variables. In the data selection i select the current month as well as the previous month and then I added a group "month". With the shared variables I pulled the last months values and displayed them at the country group for the current month. My problem comes with the drill functionality. If I drill down to the customer level, I loose the previous month value on the country group, which is logical to me because the drill creates a new SQL-query specifically for the current month. So there can be no value. I am looking for hours to find a solution for this, but could not find anything appropriate. Using additional data sources as described  in other solutions is not an option because I am working on Business-Views, which make this difficult.

I am looking forward to hearing from you

Try this idea.

Add 2 formulas
PreviousMonth
If {DateField} In LastFullMonth then
    {RevenueField}
else
     0

Similarly for the current month

You can then use those formulas to get your summaries for the country and you don't need to group by the date.

Yep, I had such an Idea as well,
but as my report gets bigger (more columns), I would need to create a formula for each column on each group level (otherwise the grouping will not be done on the server).
I will create reports like that using more than 10 columns, so this will result in much formulas which is not very good for maintenance.
Do you have any other ideas?

The only other way I can think of would be to use a subreport to get the previous month data but not sure what happens when you drill in.
