Show all data in the same row in Framework Manager Cognos - cognos

Question

I'm using IBM Cognos Framework Manager/Report Author 10.2.1
The Data looks like the following for two rows:
**Case ID Activity Date Updated**
11111 Bill Paid 09/25/2015
11111 Received Bill 08/01/2015
On my report, I need to show the following for the same exact Case:
**Case ID LAST Activity LATEST ACTIVITY Date Updated**
11111 Received Bill Bill Paid 09/25/2015
Received Paid needs to show in the same Row showing the latest
information with the 09/25/2015 Date.
Not sure how to do this in the report or even Framework Model?

Answer 1

This is tricky but a worthy question as you come across this type of data modeling regularly. I can give you a solution in the report.
The two bits you need to figure out is the maximum 'Date Updated' for each ID and the next to maximum 'Date Updated' for each ID.
Create a new data item called 'Max Date' with the following expression:
maximum([Date Updated] for [Case ID])
Create another new data item called 'Next Max Date' with the following expression:
maximum(
CASE
WHEN [Date Updated] <> [Max Date] THEN [Date Updated]
ELSE null
END
for [Case ID])
Create another data item called 'Latest Activity' with the following expression:
CASE
WHEN [Date Updated] = [Max Date] THEN [Activity]
ELSE null
END
Create yet another data item called 'LAST Activity' with the following expression:
CASE
WHEN [Date Update] = [Next Max Date] THEN [Activity]
ELSE null
END
Set the 'Aggregate Function' property of both 'Latest Activity' and 'LAST Activity' to 'Maximum'.
Summary
We calculate the maximum date for each Case ID. Next we use a CASE statement to exclude the rows that correspond to the max date and then get a maximum for each Case ID of all other rows. We create a new data item that will spit out the Activity if the date matches the max date otherwise null is emitted. We create a second data item that outputs the Activity if the date matches the next to max date otherwise spits out null. We set the aggregate function for both to 'Maximum' which has the effect of getting rid of any null values in those columns through the auto-group and summarize process. This leaves us with two new columns on each row showing the activity of the latest and the one before that.
