How to get the oracle OLAP variables value from rational OLTP database

Hi,I use the OLAP IRR function to calculate a invest index and want to get it from PLSQL package. Would you like to tell me how to approach it?

Following are my steps done for it:

I use the following OLAP DML to create AW and calculate the IRR:

aw attach IRRTEST rw

DEFINE year_d DIMENSION NUMBER

DEFINE estmodel_header_d DIMENSION NUMBER

DEFINE cflow VARIABLE DECIMAL <year_d estmodel_header_d>

DEFINE estmodel_irr_f FORMULA IRR(cflow, year_d) DECIMAL

MAINTAIN year_d ADD 1 2 3 4 5 6 7 8

MAINTAIN estmodel_header_d ADD 24

limit estmodel_header_d to 24

limit year_d to 1
