Answer / vams_gk
when a schema contains a loop u should create alias
table..alias concept not only for loops.we can also use
in fantraps.
coming to context :when u run two sql statements as a
singlestatemnt we will go for context detection process.
in traps we can choose contexts.
traps are two types chasam trap and fan trap.
these traps are situvation oriented
relation betwen muliple tables like this:
--------------------------------------0-
chasam trap :1:M:1
fan trap :1:M 1:M
really if u want o see the context how to look
tools->automatic detection----.detect contexts in BO XIr2

Answer / kiran
small correction with chasm traps..its two one ends to
single table so that would be M:1:M relation between 3
tables..

My data source is Excel sheet. How to write the SQL Statement for Excel file in data provider? Is is possible?
I need to select the rows based on the latest 'Payment_due_date' column value. Let's say I have a Deski report with 3 columns: Payment_due_date, Cust_Name, Oustanding_Amt. Report is like this: ===================================== Payment_due_date,Cust_Name,Oustanding_Amt 02/28/11 , Bob, 115 03/31/11 , Bob, 90 02/28/11 , Mike, 120 02/28/11 , Susan, 220 05/31/11 , Bob, 80, 03/31/11 , Susan, 70 05/31/11 , Mike, 220 05/31/11 , Susan, 120 04/30/11 , Susan, 130 So,we would like to see (based on latest Payment_due_date) ================== 05/31/11 , Bob, 80, 05/31/11 , Mike, 220 05/31/11 , Susan, 120 Oustanding_Amt comes as SUM(Oustanding_Amt) from Universe. If we use Max(Payment_due_date),we do get one row but then, the column 'Oustanding_Amt' sums up. Not allowed to use do SQL Override .Context Operators aren't working. Thanks in advance:)
