Average on distinct values + filter

[LisaB]

Hi,

I would like to calculate the average value based on distinct values. However, it seems like my filters on page level messes things up:

Filters: Status = Active, Item No: 100||200||300

Contract header
No (unique)	Status
CON001	Active
CON002	Active
CON003	Inactive
CON004	Active

Contract invoicing lines

Contract No	Item No	Line Amount
CON001	100	10 000
CON001	101	2 000
CON002	300	3 000
CON003	100	4 000
CON003	101	1 000
CON004	200	50 000
CON004	201	20 000

Result should be: (10 000 + 3 000 + 50 000) / 3 = 21 000

Also, if I put an additional filter on item no 200 the average should change to 50 000.

Please let me know if something is unclear.

Thanks

@LisaB ,

The dax above needs to achieve/compare previous row but there's no row number in your original table, so we need to add an index from 0 or 1 as row number.

For Line Amount you want to achieve is always the first row in each Contract No, so we should also rank the rows in each Contract No using index column.

Hi @v-yuta-msft ,

thank you for the clarification.

I don't think this formula will work for this case since there might be contracts when there is an active contract that does not include any of the ARR items. It might also be an inactive contract that include an ARR item. So only taking the first item (rank =1) will give the incorrect result.

Hi,

I have attached an example file showing my report.

I wish to show the average based on the page and report level filters. However, I would the average value to change if filtering by clicking on a bar in the chart.

Hope this clarifies.

Thank you.

@LisaB ,

Why does the Item No 101 and 201 not included? Could you please clarify more logic about this?

Hi @v-yuta-msft,

The value I want to calculate is the average ARR. Items 101 and 201 are not included in the defintion of the ARR. Hope this clarifies.

Thanks.

@LisaB ,

Firstly, build a relationship between two tables like below:

Secondly, add an index column in table 'Contract invoicing lines', then create a calculate column using DAX below:

Rank = RANKX(FILTER('Contract invoicing lines', 'Contract invoicing lines'[Contract No] = EARLIER('Contract invoicing lines'[Contract No])), 'Contract invoicing lines'[Index], , ASC, Dense)

Finally, create a slicer based on status column and create a measure in 'Contract invoicing lines' table:

Result = CALCULATE(AVERAGE('Contract invoicing lines'[Line Amount]), FILTER('Contract invoicing lines', 'Contract invoicing lines'[Rank] = 1))

Hi @v-yuta-msft ,

Thanks. Could you, if possible, please explain the functionality of index and what the rank formula does?
