IBM Cognos Report Studio: Combining multiple tuples in order to create one intersection

Question

I am consuming dimensional data (TM1 cubes) with Report Studio. I want to combine the slice given by two (or more) tuple calls. This is because I want to include two elements from the same dimension that is not logically structured in a dimensional hierarchy. An example would be if I wanted to have combine the actuals for 2012 and 2013 without first making separate data items for both. Then I would have two expressions:

tuple([Actuals], [2012])
tuple([Actuals], [2013])

To illustrate what I want, I would ideally be able to write something similar to these suggestions:

tuple([Actuals], [2012], [2013])
tuple([Actuals], set([2012], [2013]))

However, these suggestions do not work. Hence, I was wondering if there is any other way of combining the slices given by two or more tuple calls, as described earlier in this post. Thanks in advance!

Answer 2

Combining different elements from 1 dimension means addressing 2 different cells (2012, 2013 in your example) and then doing something (summing up?) to their values. Tuple function always addresses a single cell, making your idea impossible.

But combining values for different tuples is usually something along the lines: tuple([Actuals], [2012]) + tuple([Actuals], [2013])

or

total ([Actuals] within set([2012],[2013]))
