Report Issue: Previous Weeks, Current Week and Next Week Values

Question

Hello Folks,
this is a typical requirement...at-least typical for me..
we have 20 weeks of data at weekly level. we have four Metrics out of which two are coming from Database and rest two are calculated metrics.
Metric0: On Hand Qty
Metric1: Past Qty
Metric2: sell Qty
Metric3: unsell qty
Metric4: Total Qty
the report will always be shown for 20 weeks, but depending on whats my current week, all the past weeks should be flagged as Past Week. (so i wrote a case statement for this). for Instance: I am in Week11, so my weeks in should be Past Week, Wk11, Wk12.........Wk20.
Metric 1 is always dependent on result of Metric4 (This is the Complexity) per week basis
Metric1 for Past weeks value in Week Column will be wk1 to wk10 On Hand Qty (fox ex: 80)
Metric4 for Pass Weeks Value in Week Column will be Metric1 for Pastweeks + Metric2 for Past Weeks (For Ex: 20) (Past weeks mean wk1 to wk10)
value of Metric4 is now 100
Metric1 for Week11 Now should 100 (From Past weeks Calculation)
Metric4 for Week11 will be Metric1 for Week11(100) + Metric2 for Week11(10) + Metric3 for Week11 (10)
Now...Metric1 for Week12 will be 120 which is wk11 total (100+10+10) and goes on Until Week 20
Any Ideas how to achieve this in obiee 10g
Thanks

Answer 1

Please try out in this way....
Database level --Create opaque view & procedure or function  to get the week total,week ago total, current week , Past week ,future week & do rpd modelling and use PIVOT VIEW.
At answers:
1.Here Previous week M4 is the current week M1 which means it is a cumulative value carried forward week by week.
2. M2 & M3 are direct database columns.
3. You have time hierarchy with WEEK Level.
M1 - ago(rsum(m2+m3),weeklevel)
M4- RSUM(M2+M3)
week -AGO(RSUM(M2+M3)- M2-M3-RSUM(M2+M3)
w1-0-10-20-30
w2-30-11-21-62
w3-62-12-22-96
Now you can PIVOT IT to get in
W1-W2-W3
M1 0 - 30-62
M2 10-11-12
M3 20 -21-22
M4 30 - 62-96
NOW PASTWEEK (W1-W10), CURRENT WEEK(W11)-W12
1.as you see cumulative here you need to use BINS.means ( case when week <= currentweek(maybe variable) then prior) else week)
2. UNION - combine similar request - First cirteria week <= w11 and second criteria week > week 11 --combine pivot it. Use sum agg in fx criteria1.
Hope this should solve your pblm at answers.
