Ago function - Aggrgate Table.

Question

Hi , tnks in advance for your replies.
I have one aggregate table(created in by db oracle 10g/r2) where i have the sum of "qty" and "sale_price" in a level of month.
I have a calendar dimension --->year->half->quarter->month(where month is my lower level) in my business level.
i created the appropriate logical columns with the ago function for each(year ago....) in administrator tool
Everything is ok for the "year-half-quarter" but when i try to create a report with my lowest dimension "month" , it is created the following nqserror :
Κατάσταση: HY000. Κωδικός: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 46036] Internal Assertion: Condition !levelJoinNodes.empty(), file .\Src\SQONPathJoinConstructor.cpp, line 922. (HY000)
Any ideas?
tnks...

Answer 1

Tnks one more time for your response.
I checked everything again and "believe" that everything is ok.
I made a simple report with 3 collumns
One for moth,quantity and -quantity last month-
I checked in the session

where in greek:
month = Μήνα
quantity = Ποσότητα
year = Έτος
i tried the same report after adding one more column at the end,the column year.
the result was ok.
