DAX - granular reallocation - revenue inbetween a period to days

[Anonymous]

I have a table Campaign_Report:

UID_CAMPAIGN	Start	Finish	Gross Total	DurationDays	GrossTotalDay
8114	02-12-2013 0:00	08-12-2013 0:00	$33,421	7	$4,774.43
16217	02-12-2013 0:00	06-12-2013 0:00	$84,122	5	$16,824.40
28392	10-12-2013 0:00	15-12-2013 0:00	$123,123	6	$20,520.50

note that the start and finish dates are inclusive. I'd like to proportion the revenur to each day so that I have a dynamic table that looks like this:

Date	UID_CAMPAIGN	GrossTotalDay
02-12-2013 0:00	8114	$5,570.17
03-12-2013 0:00	8114	$5,570.17
04-12-2013 0:00	8114	$5,570.17
05-12-2013 0:00	8114	$5,570.17
06-12-2013 0:00	8114	$5,570.17
07-12-2013 0:00	8114	$5,570.17
08-12-2013 0:00	8114	$5,570.17
02-12-2013 0:00	16217	$21,030.50
03-12-2013 0:00	16217	$21,030.50
04-12-2013 0:00	16217	$21,030.50
05-12-2013 0:00	16217	$21,030.50
06-12-2013 0:00	16217	$21,030.50
10-12-2013 0:00	28392	$20,520.50
11-12-2013 0:00	28392	$20,520.50
12-12-2013 0:00	28392	$20,520.50
13-12-2013 0:00	28392	$20,520.50
14-12-2013 0:00	28392	$20,520.50
15-12-2013 0:00	28392	$20,520.50

So, the Date column only lists what is between each Campaign Start and Finish dates, the UID on each line and the individual daily breakdown of each. I've been trying to write a DAX formula to convert this, I have the dates in a table using 

Table = CALENDAR( minx(Campaign_Report,Campaign_Report[Start]), maxx(Campaign_Report,Campaign_Report[Finish] ))

But can anyone point me in the right direction as to DAX to split out each day total into the second table?

Hi, @Anonymous

Create a interim table:

Daily Breakdown = GENERATE(
     SUMMARIZE(Campaign_Report,
         Campaign_Report[UID_CAMPAIGN],
         Campaign_Report[GrossTotalDay],Campaign_Report[Start],Campaign_Report[Finish]),
         DATESBETWEEN(DateDimension[DateSK], min(Campaign_Report[Start]), max(Campaign_Report[Finish])
     )
 ) 

In this table, create a calculated column:

Column =
IF (
    'Daily Breakdown'[DateSK] >= 'Daily Breakdown'[Start]
        && 'Daily Breakdown'[DateSK] <= 'Daily Breakdown'[Finish],
    'Daily Breakdown'[UID_CAMPAIGN],
    BLANK ()
)

Then, create the final table that you expected:

Daily Breakdown2 = 
SELECTCOLUMNS (
    CALCULATETABLE ( 'Daily Breakdown', 'Daily Breakdown'[Column] <> BLANK () ),
    "UID_CAMPAIGN", 'Daily Breakdown'[UID_CAMPAIGN],
    "GrossTotal", 'Daily Breakdown'[GrossTotalDay],
    "Date", 'Daily Breakdown'[DateSK]
)

I've inched closer with this expression:

Daily Breakdown = GENERATE(
     SUMMARIZE(Campaign_Report,
         Campaign_Report[UID_CAMPAIGN],
         Campaign_Report[GrossTotalDay]),
         DATESBETWEEN(DateDimension[DateSK], min(Campaign_Report[Start]), max(Campaign_Report[Finish])
     )
 ) 

However DATESBETWEEN doesn't isolate the days specific to each campaign, to does all the dates of ALL campaigns. Can anyone give me a hint (if you can't tell I am new to DAX!) where to put DATESBETWEEN so it only affects the Start to Finish dates of each campaign?
