Prompt is a function in BO, that is used to get report 
containing specific data. Specific to what prompt values 
have the user entered. A prompt could be given in the query 
panel while editing the data provider for the report. 

for ex, if a prompt has been added in a column 
say "balance" ,and the prompt asks for which date the user 
wants to see the balance, then the user can either on its 
own put a value or he can also select value/values from the 
list of values.

Hi everybody,


                  prompts are the user interactive objects
which will allow the user to enter the value based on the
value the query will be executed and the results will be
displayed in the report based on the prompt value,

for eg:@prompt('enter the value for the
year','Á','class/object',mono,free)
By using this the BO will ask the user to enter the year
based on the value of year the query will be executed.

If he selects the 2001 then the year will be equal to 2001

Hi Everybody,
              Prompt is user interact object as said above.
It is limiting the result set data. Data will fetch from DB
based on what user has entered the value in prompt.

               Its improve the query performance too rather
than fetching all the data from db.

               we can create prompt from dimension object as
run time while creating the report for first time or create
predefined prompt while design the universe using @prompt.
