Quarter

Question

Hi,
I need to get the last day (working day) of the prior quarter.
DateA is the date from my facttable, and DateB have values to use (history).
I use an expression operator to calculate the correct day
ID_DateB Between (TO_DATE(CONCAT('/01',
DECODE(WB_CAL_QTR("FT_INSTRUMENTOS"."ID_DateA "),1,'JAN',2,'APR',3,'Jul',4,'Oct'),
TO_CHAR("FT_INSTRUMENTOS"."ID_DateA ",'YYYY')))) - 8 )
AND
(TO_DATE(CONCAT('/01',DECODE(WB_CAL_QTR("FT_INSTRUMENTOS"."ID_DateA "),1,'JAN',2,'APR',3,'Jul',4,'Oct'),
TO_CHAR("FT_INSTRUMENTOS"."ID_DateA ",'YYYY')))) - 1 )
But OWB put the full statment directly in my joiner-where, and the "DECODE" don't work there
I need this operation in a nested select, how can change the query code??? or what operator I must use?? other way to do this??
---After set a range of day, I use a aggregator operator and use a MAX command in the having clause to return the last day of the prior quarter.---
Thanks
