Never resolved problem

[vittorio]

What do you mean by:
"You may do it as calc. measure over variation (ctVariation) measure. You need only check which year you will take as base."
I told you that the component, as a calc type, do not include ctVariation.
I suppose you mean ctCustom. I set the property of Measure.calctype to ctCustom. Then how can I customize it???
Thanks in advance for your help

Please see examples and docs for ctCustom measure. You should use your own event handelr to calculate measure value over cube data set.
You should use
procedure OnCustomMeasure(Measure: Integer; Count: Integer; Data: OleVariant; var Value: Double); dispid 222;

where
Data - variant array of doubles from 0 to Count - 1
Value - output value of cell

Please check what you really want to get. I tried to answer to that question but I still could not understand what you want to get, so I may miss right answer.
