How to create a UNION between two custom folders

Question

Hi all, I have two different dataset based respectively on two custom folders: CF1 and CF2
The first custom folder (CF1) is joined with a custom folder called Groups and retrieve the amount of tickets_id which are owned by the groups.
The second custom folder (CF2) is joined with another custom folder called User and retrieve the amount of tickets_id which have been created by the users.
This two sets, as you have understood are independents and not correlated, because the two different amount of tickets_id follow two different logics....
However, now I need to have a single field called TICKET_ID which is the UNION (not UNION ALL) of all tickets_id retrieved by CF1 and CF2
I tried to use a complex folder...but it showed always two distinct fields...instead I want to merge the two dataset into a single field called TICKET_ID
Is there a way or a workaround to resolve this problem ???
Thanks a lot in advance

Hi Rod, just an explanation...
I red and follow the threads you mentioned in your previous mails and I'm using the context.
I summarized what I did
1) I created the context and the package (with the 2 functions inside)
2) I created on the Administrator a custom folder with the following sql:
select vl.user_id,g.group_id
from apps.jtf_rs_emp_dtls_vl vl,
apps.jtf_rs_group_members_vl g
where g.resource_id = vl.resource_id
and (g.delete_flag = 'N' AND vl.end_date_active IS NULL)
and g.group_id = COMPLAINTS_GET_GROUP_ID(SYS_CONTEXT('DISCO_CONTEXT','GROUP'))
where COMPLAINTS_GET_GROUP_ID is the package name which contains the 2 function SET_CONTEXT and SHOW_CONTEXT, even if I use directly the SYS_CONTEXT function....
3) Inside my workbook I have 2 sheets and one parameter (called GROUP):
a. inside the first sheet I created the calculated field which set the parameter value with the following code : SET_CONTEXT('GROUP',:GROUP)
b. inside the second sheet I show the list of user_id retrieved from the select above
This mechanism works perfectly, even if the refresh of the parameters on the first sheet is mandatory to see the right data on the second one. But this works ONLY if my parameter GROUP has ONLY one value....
Now I have the necessity to pass to the select a LOV of groups !
Reading the previous threads I saw that there are two ways to solve this problem: (Re: Parameters in SubQuery
a. - join your subquery to you list of values folder. If you have a parameter that is based on a LOV then there will be a folder that defines the LOV. You should be able to join the subquery folder to the LOV folder either in the EUL or in a custom folder and use the parameter to select from the LOV folder.
I can't use this option because inside the same custom folder I need to have a UNION of 2 different select with their separated joins
b. use multiple parameters, so you define a fixed number of optional parameters, say, PARAM1,PARAM2,PARAM3,PARAM4 and PARAM5. Then set them in a separate workbook and then use a condition col IN (SYS_CONTEXT('NAMESPACE','PARAM1'), SYS_CONTEXT('NAMESPACE','PARAM2'), SYS_CONTEXT('NAMESPACE','PARAM3'), SYS_CONTEXT('NAMESPACE','PARAM4'), SYS_CONTEXT('NAMESPACE','PARAM5'))
This solution is very interesting but I didn't understand how to implement it (remember that I have only one parameter "GROUP" with more than on value).
How can I modify the calculation and the condition inside the select ?
Thanks a lot
