Using offsets in the query

Question

I am using a custom calendar which will always have 52 weeks. Now i need to display 5 weeks past and 5 weeks future(forecast) data in my query.
While using offset query is taking the system weeks.
For eg. When i enter current week as 01.2005
Current week -1 ( with offset -1) should be 52.2004 in my case but it is showing 53.2004 and no data in front of it.
Is it possible to have 52 weeks for all the years as per my custom calendar and implement offsets for the same ?

Hi,
Sorry for the late Reply for a better solution..
Do this..
Create a Variable zcalweek as reference of 0calweek (standard one). Now you are saying that you are facinf problem at year starting and year end(if offset +1). To cater that..you can do this..
Create a USer-entry variable for ZCALweek.
Now create a custome exit variable on zcalweek and derive normal value from zcalweek while using offset...the problem is at start of year and end of year...
so Add this code in your custom exit..
If week+4(2) = '01'. '01.2005
'week+4(2) = '52'.
or better solution is do this..
Select single max(week) from /bic/odsname00 where year = week+4. 'this will give either 53 or 52 as per max value in that year
week+4(2) = week. '522005
week0(4) = week0(4) - 1. 'week = 522004
else.
week - 1. 'if week not eq to 01.2005..directly apply minus 1
endif.
Hope i m clr.
