Fiscal Period is not working on weekly level

Question

Hello,
I am building this query where users can use the fiscal period on the weekly level. We do have weekly variant maintained in 0fiscvarnt. Problem is every time I execute the query on weekly level its doesnt not bring in any data but if I execute the query on period level, it brings in tons of data.
Example: if I execute the query with the following setting it would not bring in any data.
Fiscal period: 001/2008 - 052/2008
fiscal period variant: AB (weekly based, 001 - 053)
If I execute the with following settings it would bring lots of data.
Fiscal Period: 001/2008 - 012/2008
Fiscal period variant: YZ (Month based, 4-4-5)
Addition to that, there is no data available in the cube for fiscal variant:AB (weekly based).
Any suggestion would be appreciated.
Thanks,

what you can do is :
For reporting based on fiscal month periods create a cube and populate it.
Put in the time dimension all 0Fisc* infoobjects.
Do the same for weeks.
So --> 2 cubes : one with fiscal variant month, the other with weeks.
let's say Cubefiscweek and Cubefiscmonth
In order to convert to fiscal periods base on a date you have some standard function like date_to_period_convert.
For example you have the day of transaction purchasing or sales take the date and convert it in the transformation with a routine.
One important setting :
Make sure you retrieved the global settings form source system regarding the fiscal periods.
Maintain the fiscal variant in tx ob29 or gvar for the week variant and the month variants.
Maybe this tasks is already done in source system so you just need to recover the global setting in BW.  Check if tables T009x are maintained (the one that is important is t009b)
If they are not maintained ask a functional to give the repartition.
