Hi, CA, welcome. Please note that your question really has nothing to do with this blog post. As per my support policy I would suggest that you post your question on BOB instead. Thanks.

Hi Dave,
Thanks for your tips.Its really helpful to novices like me in BO.

My users need to get report in email, which will tell them from which DB/env the report data are coming from either in the subject line/mail body or report name.Can this be possible through scheduling report feature in XI R2?Dynamically appending the DB/Env name while running and fetching data?

Dave,

I finally was able to make so progress on this.

@Select(Transaction Details\Transaction Date) = COALESCE(
(case when dayofweek(CURRENT_DATE) = 2 then (CURRENT DATE – 3 days)
when dayofweek(CURRENT_DATE)=3 then (CURRENT DATE – 2 days)
ELSE (CURRENT DATE – 1 days)
END),CURRENT_DATE)

But I would like to add to the when dayofweek(CURRENT_DATE)=3 then (CURRENT DATE – 2 days) part.. if current_date =3 I actually need to pull Current date – 2 and current date – 1.

Any ideas?

Thanks again,

Hey Dave, I have read over the blogs entries above, and also review the BOB website. I can not seem to figure out how to use the dayofweek function when trying to create a predefined condition.

In short, I am trying to identify which day it is, and then subtract x number of days from a transaction date data object within my universe.

Here is the code I have to date.
Case when dayofweek(CURRENT_DATE)=2 then
@Select(Transaction Details\Transaction Date) = (current_date – 3 days)
when dayofweek(CURRENT_DATE)=3 then
@Select(Transaction Details\Transaction Date) = (current_date – 1 days)
END

I get the following error when I try to parse my condition.

[IBM][CLI Driver][DB2] SQL0104N An unexpected token “=” was found following “”. Expected tokens may include: “END”. SQLSTATE=42601
:-104

I appreciate any help.

Thanks,

Hi, David, and welcome. If you have any non-standard issues to deal with I much prefer to use a calendar table than try to work with database functions. It makes the solution much cleaner that way.

How do you deal with this in business days including holidays. This is critical in financial data?

Tbaby, welcome and thank you for your comment. Your question isn’t solved by creating dynamic date objects, it’s going to be solved by using a calendar table and multiple query passes. In other words, a completely different approach. I am in the process of writing up one way to do this for a presentation at the user conference next month (October) in Dallas. It’s fairly complex, and not something I am able to answer here in the limited space, and not on this post since it’s a completely different technique.

Come back in a month and you should be able to download the presentation from my conferences page.

Dave,
Pls can you kindly help me to figure this out;
I have succeeded in creating my previuos and current month object, but i want their corresponding revenue to be display on a separate column and the measure object not aggregated. How do i go about it.

Note; If create a report with both objects(previous & current month), i want to display each of the data on a separate column.
I await your prompt response.
