Problem with calculating measures in AWM

Question

Hi,
We created dimensions and cubes in AWM (or in OWB) - without using materialized views. We we maintain cube using sum, min and max aggregation function eberythink is OK - we can see data in views, but when we maintain cube using other function e.g. average we see, that in view we have aggregated data using sum function, so:
sum makes sum
min makes min
max makes max
other functions makes sum

what to do? maybe we don't understand something?

Answer 1

One more time:
Hello,
I checked it. Unfortunately You're wrigth. I have simple CUBE AW_T5_V2 with three measures:
cena,
przebieg,
rok
and two simple dimensions:
aw_kolor with levels
KOLOR and
ODCIEN (ODCIEN_ID is foreign key)
aw_model with levels
MARKA
MODEL
SILNIK (SILNIK_ID is foreign key)
In point 1. and 2. everything is OK. (I mean in cube definition in dba_cubes:
SOLVE
AVG
ALLOW OVERFLOW
ALLOW DIVISION BY ZERO
IGNORE NULLS OVER CPOWBADMHD.AW_KOLOR,
AVG
ALLOW OVERFLOW
ALLOW DIVISION BY ZERO
IGNORE NULLS OVER CPOWBADMHD.AW_MODEL
and in AGG_MAP definition in OLAP Worksheet
DEFINE AW_T5_V2_SOLVE_AGGMAP AGGMAP LOCKDFN
AGGMAP
RELATION this_aw!AW_KOLOR_AGGRREL(this_aw!AW_T5_V2_SOLVE_AW_KOLOR_HVSET) PRECOMPUTE(NA) OPERATOR AVERAGE args DIVIDEBYZERO YES DECIMALOVERFLOW YES NASKIP YES COUNT YES
RELATION this_aw!AW_MODEL_AGGRREL(this_aw!AW_T5_V2_SOLVE_AW_MODEL_HVSET) PRECOMPUTE(NA) OPERATOR AVERAGE args DIVIDEBYZERO YES DECIMALOVERFLOW YES NASKIP YES COUNT YES

But in cube_build_log I can see script in OUTPUT column:
<SQL>

ORDER BY

T14_ODCIEN_ID ASC NULLS LAST ]]>/>
</SQL>
It should be AVG, where is SUM (I've checked that, when I update agg method to min or max function is changing from sum to mix or max). I suppose SQL should sum measures and devide by number of records.
OK, we know where is bug, what to do?
