## Cumulative Multiplication measure

Hello,

I am trying to create a dynamic measure that multiplies the value for all dates before today.  I do not know how to do this in Power BI.  Can anyone help?

For example- I am looking to replicate the values after calculation.  These are just the cumulative multiplied Value 1 for each day:

 Day Value 1 Value After calculation Mon 1.1 1.1 Tues 1.15 1.265 Weds 1.12 1.4168 Thurs 1.16 1.643488 Friday 1.09 1.79140192

@ARob198 not sure what you are referring to purple, share screenshot, here is how you can add 2nd filter

Measure =
VAR __d = MAX ( 'Day'[Index] )
RETURN CALCULATE ( PRODUCTX ( 'Day', [Value 1] ),
ALLSELECTED ( 'Day' ), 'Day'[Index] <= __d, 'Date'[Date] > DATE(2016,1,1) )

I would  Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!

@Anonymous sorry not fully clear what you are looking for. If you can provide a sample pbix with the expected output, it will help to provide the solution.

Hey @ARob198 ,

this is not as simple as we may wish 🙂

Fortunately, it possible to achieve this by leveraging the table iterator function PRODUCTX.

As PRODUCTX expects a table as the first parameter, you have to order the Day e.g., by creating a new column like DayIndex with 1 for Monday, 2 for Tuesday, ...

Then you can create a measure similar to this:

measure =
PRODUCTX(
FILTER(
'tablename'
,'tablename'[DayIndex] <= MAX('tablename'[DayIndex])
)
,'tablename'[Value]
)

This blog post describes what's going on by using PRODUCTX in much more detail.

Hopefully, this provides what you are looking for.

Regards,

Tom

Hi All,

I have a Date in the model so I believe that should work instead of an index column.  However, how to I add a filter to have it start caclulating on a certain date.  Both of the ways you suggested are resulting in a 0 value which I suspect might be becuase the very first value is a 0.  Therefore, multiplying anything by 0 = 0.  I tried adding a second filter 'Values[DATE] > "12/31/2016" and also Values[DATE] > 42735 but it doesn't seem to work.  How can I add a second filter?

On another note, why do some components of measures in Power BI turn purple?  As in the formula bar text becomes purple?  What does that mean?

Thank you very much

The formula is giving me 0s.  Even though my data has values for the columns to be multiplied- as in the post above.  The MTD Int is the value that I need to use for the cumulative multiplication.  Any thoughts on how to get this to work or even to trouble shoot this?  Thank you

@ARob198 Hello, did you solve this problem?

At this point I get into the same problem that you pose I want to do a cumulative multiplication but all the values appear to me in 0.

I'd appreciate it if you help me, thanks!

Helper IV

Thank you.  Here is a screenshot of the purple text and my formula.  It doesn't seem to be working for me, I am not sure why.  The MTD INT calculation is working so I just need it the ITD to be a cumulative multiplied table on this number.  What the best way to trouble shoot this?

@ARob198 that shows it is a measure.

@ARob198 add an index column in power query as it is required to set the order for the day, after index column is added, apply the changes,

select day column and sort it by index and add the following measure

Measure =
VAR __d = MAX ( 'Day'[Index] )
RETURN CALCULATE ( PRODUCTX ( 'Day', [Value 1] ), ALLSELECTED ( 'Day' ), 'Day'[Index] <= __d )

Hi, I had a similar problem. I am creating this recurring product, But encountering issue where the memory is full as its about 38k rows. Is there any way to come around this issue for a similar logical outcome?
