Values becomes #available or #error after formaula

Question

Hi All,
I am creating a webi report on SAP universe.
Problem :
Whenever I apply any date related formala on the date field , all the values in the measure becomes #error or #available .
Additional informaion :
it has got say 6 fields like Cusotmer , sales material and Date ( making it one dimension) and Profit , quanity sold and amount as measures.
I created a formaula on date field and added 4 days to the current date.
Now what happens is if I dragged this new formaula object to webi output area all my measures become #error or #un available.
When i remove this newly created formaula from result area , all the values comes back .
This happend also when I wanted to find out the name of the day on a particular date and drangged onto my resultant area.
After this all the measure values in the webi got #error or #available error.
Any help is highly appreciated.
Thanks & Regards,

Hi,
The measures you use are probably set to aggregate using "database aggregation"
(properties tab of the object definition) as this is the default when you generate a universe on SAP BW.
What that tells BO is that you want the database (in this case BW) to calculate the measure on each datapoint in the report separately. However BW doesn't know about this new dimension object (its not a BW characteristic), so BO states that it cannot give you the value at that datapoint.
Ask your designer to set the object aggregation of measures to sum (this is the most likely candidate),
this will allow the aggregation to be done by Webi internally.
Hope this helps,
