Return Date If Stock <= 0

[TotunG]

Hi there,

I am struggling to implement the above in my Power BI and have tried other similar solutions using CALCULATE / MINX / FILTER etc. I basically want to have it so that a date can be seen in my matrix visual that will appear for when a stock for the particular item will reach 0 (IF it does, IF NOT THEN it does not have to return a value.

My table is as follows:

TYPE	ITEM	STOCK	DATE
A	Apple	2000	07/11/22
A	Apple	0	14/11/22
C	Banana	500	28/11/22
C	Banana	0	21/11/22
C	Banana	-222	28/11/22
A	Carrot	1000	01/01/23
D	Nuts	-2421	01/03/24
D	Nuts	-5002	08/03/24

For example, this should hopefully show:

TYPE	ITEM	EARLIEST DATE
A	Apple	14/11/22
C	Banana	21/11/22
D	Nuts	01/03/24

Any ideas on how to achieve this either through DAX or a Measure?

Thanks in advance.

Hi @TotunG ,

Has your problem solved by @johnt75 's solution? If not, try this:

Measure:

Earliest date =
CALCULATE (
    MIN ( 'Table'[Date] ),
    FILTER (
        ALL ( 'Table' ),
        'Table'[Type] = MAX ( 'Table'[TYPE] )
            && 'Table'[Item] = MAX ( 'Table'[ITEM] )
            && 'Table'[Stock] <= 0
    )
)

Or calculated column:

Column =
CALCULATE (
    MIN ( 'Table'[Date] ),
    FILTER (
        'Table',
        'Table'[Type] = EARLIER ( 'Table'[TYPE] )
            && 'Table'[Item] = EARLIER ( 'Table'[ITEM] )
            && 'Table'[Stock] <= 0
    )
)

I attach my sample below for your reference.

Try

Earliest date =
CALCULATE (
    MIN ( 'Table'[Date] ),
    ALLEXCEPT ( 'Table', 'Table'[Type], 'Table'[Item] ),
    'Table'[Stock] <= 0
)

Thanks for the quick reply - This as a Column made it say 01/01/2022 for all values but thank you for the suggestion.

[johnt75]

I meant it as a measure. If you need it as a column it would need some tweaks.

[TotunG]

Ah apologies - Still the same result unfortunately. Thank you though.

[johnt75]

It works in my sample

Do you have any filters being applied to other tables? They may need to be removed using REMOVEFILTERS in the CALCULATE statement

[TotunG]

Okay I see - Whereabouts exactly would I put REMOVEFILTERS? Can't see that there is any filters but you're right that it looks like its working for you. 

[johnt75]

Not sure if this will work but you can try

Earliest date =
CALCULATE (
    MIN ( 'Table'[Date] ),
    ALLEXCEPT ( 'Table', 'Table'[Type], 'Table'[Item] ),
    REMOVEFILTERS(),
    'Table'[Stock] <= 0
)

Not sure how the REMOVEFILTERS will interact with the ALLEXCEPT. You may need to specify each table that is connected to your main table individually, one per line, each in their own REMOVEFILTERS call.
