WEBI - unverses: create rolling measures

Question

hi all,
i'm working with webi on olap universes on bex queries.
i need to create a rolling measure that, for every year/month, aggregates the current month and the previous 11 (every month contain the values of an year).
i used this code creating a new object in universe:
<EXPRESSION>(AGGREGATE([0CALMONTH].CurrentMember.Lag(11):[0CALMONTH].CurrentMember,[Measures].[4NQFO211SO3LFWE1RV0PLRFXR]) )</EXPRESSION>
but it doesn't work well.
do you have ideas to correct my code?
thanks all!

Answer 1

Hi,
1)To have a range of months as input
2)Create a table in which for each month in the range (in rows), the following 12 months of forecast are displayed (in columns)
As far as I know EXITs based on input from user are still not supported.
Probably it is not the classic rolling forecast scenario, but this is why I told "It depends on complexity of report".
>> EXIT Variables with Input are supported. the part that is not supported in XI 3.1 is the fact that the default value is set in the prompting dialog but the user will receive the values.
To me the scenario clearly requires an EXIT variable as otherwise you can not leverage the system date from the BW system and you are back to having to ask for 2 dates as a date range.
if you want to create 12 keyfigures or 1 - that depends to some degree on what the report is supposed to look like and what the user is supposed to be able to do with the data.
