Hi Lars,

can you kindly verify your explanation about uniqueness of option codes?

It would be great if they hadn't to be unique system-wide, but I just tested it
on snapshot, and it seems to me that option codes codes must still be unique.
Which is in fact not really interesting: this way you cannot use simple F and M
for female/male as F might stand for False in another category. This is
especially difficult when you are dependent on the codes that are coming from a
source system.

My temporary solution is to prefix each code with a code for the category e.g.
GEN.F/GEN.M for gender female/male and HPY.T/HPY.F for happy or not happy. But
that's not really nice for the outputs and exports. Imagine having a simple
number code (like Month) that is presented as MON.10, Mon.11 etc. in charts and
pivots ...

Thanks and regards, 

Uwe
