Filtering null values on a card

There was an error rendering this rich post.

I have beastmodes to calculate change in margin over years and I am trying to filter out when all three columns are null to keep only active fields. ( If one column has a change then all three columns should show) only filter when all three are null.

I made a beastmode but it seems to be giving me some trouble.

@gbrown Can you please share the beast mode you are using?

They are fairly long which could be causing the issue...

Change in Margin - 2020 to 2021:

(SUM(CASE WHEN YEAR(`Period Date.1`) = YEAR(SUBDATE(CURDATE(), interval 1 year)) AND MONTH(`Period Date.1`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date.1`) < DAYOFYEAR(CURDATE()) THEN `Net Sales Amount` END)

SUM(CASE WHEN YEAR(`Period Date`) = YEAR(SUBDATE(CURDATE(), interval 1 year)) AND MONTH(`Period Date`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date`) < DAYOFYEAR(CURDATE()) THEN `Amount` END))

SUM(CASE WHEN YEAR(`Period Date.1`) = YEAR(SUBDATE(CURDATE(), interval 1 year)) AND MONTH(`Period Date.1`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date.1`) < DAYOFYEAR(CURDATE()) THEN `Net Sales Amount` END)

(SUM(CASE WHEN YEAR(`Period Date.1`) = YEAR(SUBDATE(CURDATE(), interval 2 year)) AND MONTH(`Period Date.1`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date.1`) < DAYOFYEAR(CURDATE()) THEN `Net Sales Amount` END)

SUM(CASE WHEN YEAR(`Period Date`) = YEAR(SUBDATE(CURDATE(), interval 2 year)) AND MONTH(`Period Date`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date`) < DAYOFYEAR(CURDATE()) THEN `Amount` END))

SUM(CASE WHEN YEAR(`Period Date.1`) = YEAR(SUBDATE(CURDATE(), interval 2 year)) AND MONTH(`Period Date.1`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date.1`) < DAYOFYEAR(CURDATE()) THEN `Net Sales Amount` END)

Change in Margin - 2021 to 2022:

((CASE WHEN `Net Sales`= 'Net Sales' THEN SUM(CASE WHEN YEAR(`Period Date`) = YEAR(SUBDATE(CURDATE(), interval 1 day)) AND MONTH(`Period Date`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date`) <= DAYOFYEAR(CURDATE()) THEN `Net Sales Amount` END) END)

(CASE WHEN `cost type`= 'COGS' THEN SUM(CASE WHEN YEAR(`Period Date`) = YEAR(SUBDATE(CURDATE(), interval 1 day)) AND MONTH(`Period Date`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date`) <= DAYOFYEAR(CURDATE()) THEN `Amount` END) END))

(CASE WHEN `Net Sales`= 'Net Sales' THEN SUM(CASE WHEN YEAR(`Period Date`) = YEAR(SUBDATE(CURDATE(), interval 1 day)) AND MONTH(`Period Date`) <= MONTH(SUBDATE(CURDATE(), interval 1 day)) AND DAYOFYEAR(`Period Date`) <= DAYOFYEAR(CURDATE()) THEN `Net Sales Amount` END) END)

@gbrown how are you filtering? are you filtering on each beast mode where equal to null? (I.e. 3 filters in the filter section?) Because that would filter out any rows where they are null even if the others all null and you'd only get rows where all three are not null.

gbrown

@mhouston i was using the following beastmodes above in a CASE statement using the AND function making each one IS NULL then 'filter out' else 'keep' end

McSQL

@mhouston I did a test with this beast mode and the logic seemed to work as expected so I think you are on the right track. It is essentially the same is as what you described but without the actual margin calculations.

case when `margin1` is null and `margin2` is null and `margin3` is null then 'filter out' else 'keep' end

It may be worth rebuilding the query again to make sure that it was compiled correctly. You should be able to plug in the margin calcs into the parenthesis below and try it.

case when (2020-2021 code here) is null and (2021-2022 code here) is null and (2020-2022 code here) is null then 'filter out' else 'keep' end
