NEXTSIBLING in fix using Period dimension
I have a question about NEXTSIBLING using in FIX.
I would like to see
My period dimension is standard with native hierarchy:
YEartotal /// Q1 /// Jan /// Feb /// Mar /// Q2 ....
If closed month is Jan or Feb my fix working fine, but if ClosedMonth is Mar/Jun/Aug...is not working because machine choose Q1/Q2...
How can I fix this? I don't want to create additional variable called OpenMonth..
