fact table design issue

I have a database with few tables, ex.:

• users (Id, Name)
• Status (Id, Name)
• log (uniqueId, lead_id, call_date,status_id,user_id, Phone_number)

• list (lead_id, last_local_call_date,status_id,user_id, Phone_number)

LeadId        PhoneId          Entry_date

55                12345                 1Aug

111              12345               10Nov

Requirement;

RedCall Measure :

i need to do calculation (using case statement) based on entry date and lead_id where (entrydate+20  days) of particular leadId greater than max of call_date of that lead id. If condition is true then 1 else zero .

Make sure for particualr lead_id we have to assign only 1 only onetime. 

Like in above case in lead_id 55 both 25 nov and 5 oct satisfy greater than (entrydate+20  days)  but we will assign 1 to max of satisfying condition i.e, 5 oct.

so i used this query in dsv.

SELECT
t2.uniqueID,t2.Lead_ID,t2.phone_number,t2.call_date,t1.entry_date,t2.list_id,
t2.length_in_sec,t2.user,t2.status,
CASE WHEN t2.call_date = t3.call_date THEN 1 ELSE 0 END as "RedCalls"
FROM asterisk.vicidial_log t2
Inner join (select entry_date,lead_id from
asterisk.vicidial_list)t1 on t1.lead_ID = t2.lead_ID
LEFT JOIN
(  select lead_ID,MAX(call_date) as call_date
   from asterisk.vicidial_log
     group by lead_ID
)t3 ON t3.lead_ID = t1.lead_ID
AND t3.call_date >= DATE_ADD(t1.entry_date, INTERVAL 22 DAY)

i need more measure based on such condition from this log table when i create measure using named Query in dsv My Query is hanged .

Kindly suggest something  me for creating Fact table for my cube in efficient manner.

I am very new to SSAS and your suggestion and opinion will be very useful to me.

i first think i'll create my fact table outside.

i dont know the efficeint manner .

Kindly suggest needful.
