How to create a Parameter with LOV

Question

Hello All,
I am having the follwoing custom query.
SELECT concatenated_segments, (SUM(PERIOD_NET_DR)-SUM(PERIOD_NET_CR)) MOVEMENT
FROM gl_balances a, gl_code_combinations_kfv b
where period_name='Apr-08'
and a.code_combination_id = b.code_combination_id
and set_of_books_id=1010
and currency_code='USD'
gROUP BY concatenated_Segments
HAVING (SUM(PERIOD_NET_DR)-SUM(PERIOD_NET_CR))<>0.
Instead of hard coding the values I have created the custom folder
with the follwoing query.
SELECT concatenated_segments, (SUM(PERIOD_NET_DR)-SUM(PERIOD_NET_CR)) MOVEMENT
FROM gl_balances a, gl_code_combinations_kfv b
where a.code_combination_id = b.code_combination_id
gROUP BY concatenated_Segments
HAVING (SUM(PERIOD_NET_DR)-SUM(PERIOD_NET_CR))<>0.
Now I have to create three input parameters period_name,set_of_books_id,currency_code.
The parameter set_of_books_id should have list of values so that the user will select one from it at run time. But when I tried to create the parameter
I am unable to create list of values for this parameter. (i.e in Parameter dialog box the For Item filed doest not have any field like set_of_books_id as it is custom query)
So how Can I add LOV for this parameter.
Kind Regards,
PRaveen.

Hi,
You custom folder needs to contain a statement like :
SELECT concatenated_segments, period_name,set_of_books_id,currency_code, (SUM(PERIOD_NET_DR)-SUM(PERIOD_NET_CR)) MOVEMENT
FROM gl_balances a, gl_code_combinations_kfv b
where a.code_combination_id = b.code_combination_id
gROUP BY concatenated_Segments, period_name,set_of_books_id,currency_code
HAVING (SUM(PERIOD_NET_DR)-SUM(PERIOD_NET_CR))<>0.
The you will have the period_name,set_of_books_id,currency_code items in the folder and can create parameters using these columns.
To define the LOV you will need to create separate folders that return the list of values required e.g.
SELECT set_of_books_id, name
FROM GL_SETS_OF_BOOKS
Use this folder to define an item class and then include the set_of_books_id from the first folder into the item class.
