I have 2 fields and wish to express one as the percentage of another within an auto-crosstab.
Is this possible in 11.5 or will I have to use manual crosstab?

Grid looks like this currently:

Area       | C1 | C2
--------------------
Grouping 1 | 20 | 15
Grouping 2 | 30 | 20

I'd like to have another column on the end of this crosstab showing C2 as a percentage of C1.

I don't think there is a way to do it in CR11 although I think you can do it in 2008.

The only way I can think to get around this is to have the percentage as a column in the source SQL but that only works if you are getting the data out of the database as you wish to display it rather than aggregating from source data within Crystal.

You could always try it as a SQL expression I suppose, that may have the desired effect.

I ended up just building this as a manual table in the end.
