BPC: LookUpCube and double hierachies

Question

Hy,
I've got a problem using a formula containing a lookupcube in a dimension with 2 hierarchies.
This is the situation:
- first I had only a hierarchy with an account, PREFISSO_J_COAN, using this formula
*function FC_PREFISSO_J_COAN
LOOKUPCUBE("HR","([CONTI_DI_ANALISI].[H1].[PREFISSO_J],[DIPENDENTI_HR].[TOT_DIP],[MEASURES].[PERIODIC],"Tempo.currentmember.Uniquename","PDV.currentmember.Uniquename","CENTRI_ATT.currentmember.Uniquename","CATEGORIE.currentmember.Uniquename")")
*endfunction
- in a second step I added a second hierarchy and the formula became
*Function HIR1(%Arg%)
iif(conti_di_analisi.H2.CurrentMember is [conti_di_analisi].[H2].[All conti_di_analisi.H2] ,%Arg%,Null)
*endfunction
*function FC_PREFISSO_J_COAN
HIR1(LOOKUPCUBE("HR","([CONTI_DI_ANALISI].[H1].[PREFISSO_J],[DIPENDENTI_HR].[TOT_DIP],[MEASURES].[PERIODIC],"Tempo.currentmember.Uniquename","PDV.currentmember.Uniquename","CENTRI_ATT.currentmember.Uniquename","CATEGORIE.currentmember.Uniquename")"))
*endfunction
- then I had to add this account in the second hierarchy, so I create a second fourmula  working on the second hierachy
ID                                  PARENTH1               PARENTH2   ACCTYPE    FORMULAH1                                                   FORMULAH2
PREFISSO_J_COAN    PREFISSO_J_TOT    Personale     EXP              FC_PREFISSO_J_COAN, SOLVE_ORDER=5 FC_PREFISSO_J_COAN_H2, SOLVE_ORDER=5
*Function HIR2(%Arg%)
iif(conti_di_analisi.H1.CurrentMember is [conti_di_analisi].[H1].[All conti_di_analisi.H1] ,%Arg%,Null)
*endfunction
*function FC_PREFISSO_J_COAN_H2
HIR2(LOOKUPCUBE("HR","([CONTI_DI_ANALISI].[H1].[PREFISSO_J],[DIPENDENTI_HR].[TOT_DIP],[MEASURES].[PERIODIC],"Tempo.currentmember.Uniquename","PDV.currentmember.Uniquename","CENTRI_ATT.currentmember.Uniquename","CATEGORIE.currentmember.Uniquename")"))
*endfunction
and this is the problem:
The account works correctly in both the hierarchies, but the parent in the second one doesn't: it does not include the value of this child while the parent in the first one does....
Anybody can suggest me any ideas????
Thanks

Hi Letizia,
What BPC version & database are you running?
I'm not familiar with the LOOKUPCUBE syntax (nor Italian) so at a quick glance I don't understand all of your calculation requirements for the base accounts. I can see you're looking up something in an HR cube.
My approach would be to calculate the PREFISSO_J_COAN account in script logic (either SQL or MDX), so that the values are posted to the fact table.
Then it's easier to confirm whether the aggregations to the parents H1 and H2 are working correctly or incorrectly.
If you choose to use the member formulas, as a first step, have you confirmed that if you remove the member formula (temporarily) and save a value to the base account, does it properly aggregate across the 2 dimensions? (I'm sure it will.)
I encountered problems about a year ago on BPC 5.0 / SQL 2005 with member formulas (much simpler than your formula) in account dimension, when there are more than 1 hierarchy in that dimension. It was very difficult to reproduce, and by the time it was confirmed as a software defect I'd long since found a different way to calculate the account.
