(Sysdate-1) in filename using scheduler and ftp

Question

Hello,
I'm having a little problem with BI Publisher.
What i am trying to do is use the sysdate-1 in the filename when using the scheduler in BIP.
I found out that for using the regular date there are functions like %d %m %y, so obviously the first thing i tried was using the %d-1 but that didn't work :(
Then i went looking on the internet and found the following article:
http://obiee-bip.blogspot.com/2010/05/dynamic-delivery-file-naming-in-bi.html
This mentions things like:
dd : CAST( DAYOFMONTH(NOW()) AS CHAR) ( ex, 01 - 31)
mon : CAST( SUBSTRING(MONTHNAME(NOW()) FROM 1 FOR 3) AS CHAR) (ex, Jan - Dec)
yyyy : CAST( YEAR(NOW()) AS CHAR) (ex, 2006,2010)
But when i use those in the same filename field then it just displays the string as text in the filename.
Could someone tell me what i am doing wrong, or what i need to do to make this work?
Thanks in advance

Hi Raafje,
Like I've already discussed in my Blog ,Using Date Expressions on Filenames of Burst Query has its own limitations. This date expression that you have tried for sysdate-1 (%d-1%m%y) will not hold good to the requirement. Anyways you can resolve the issue using other work arounds.
Method I (Using CAST and DATE Functions)
1.Previous Day -> CAST(DAYOFMONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)
2.Month of Previous Day -> CAST(MONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE ) ) AS CHAR)
3.Year of Previous Day -> CAST(YEAR(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)
Sample Code
+'ReportName'||'-'||CAST( DAYOFMONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)||'-'||CAST(MONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE ) ) AS CHAR)||'-'||CAST( YEAR(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)||'.pdf'+
Method II (Using Server Variables)
1. Create a Dynamic Repository Variable like Previous_Date(Non-System Session variables can also be used)
2. Create a Initialization blocks
In Data Source Section - Edit Data Source and place the below query
Select TO_CHAR(SYSDATE-1,'MM/DD/YYYY')
FROM Dual (you can use any date format as required)
3. In Variable Target Section
Edit Target -
Give the Name as Previous_Date (as you created in Step1) and Enable the Radio Button as Dynamic
Place date in Default Value like '9/22/2010'
4. Now use this Repository Variable in the filename parameter of the burst query as VALUEOF("Previous_Date") for Repository Variable
and VALUEOF(NQ_SESSION.Previous_Date) in case you have created a session variable for the query
