Slow calculate column measure

keny999 — Fri, 28 Jan 2022 12:08:32 GMT

Hi,

i've got some measure that calculate cummulative of [Plan_Ilość], and it's in the calculate column but it is very slow, how can I do that it can be faster ?:

var _Rok_mc = Plan_prod_TTL_etap_0[Rok_m-c_2]

var _Kod = Plan_prod_TTL_etap_0[Kod_produktu]

return

CALCULATE(SUM(Plan_prod_TTL_etap_0[Plan_Ilość]);

KEEPFILTERS(

FILTER(

Plan_prod_TTL_etap_0;_Rok_mc>=Plan_prod_TTL_etap_0[Rok_m-c_2]
&&
_Kod=Plan_prod_TTL_etap_0[Kod_produktu])
);Plan_prod_TTL_etap_0)

Hi,

For running total I recommend this pattern:

Period RT =

VAR MaxDate = MAX ( 'Calendar'[Date] )

RETURN

CALCULATE (

SUM(Cumulativetotal[Value]),

'Calendar example'[Date] <= MaxDate,

ALL( 'Calendar' ) )

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!

Hi,

If the calculation is still very slow I suspect that the problem lies elsewhere. There are multiple way to optimize a model and it is hard to explain them here. For now I recommend checking your visuals using the built in report analyzer or using tool like DAX studio or BPA analyzer in tabular editor.

I'm in the power pivot and have about 7 000 rows and when wrote the measure I'm waiting and waiting....:

Hi keny999 ,

I think that your large amount of data and the complexity of the model are causing the calculated column to run slowly, please try to optimize the model. Data reduction techniques for Import modeling

Also, according to the documentation, it is recommended that you create custom columns in Power Query (defined in M) instead of using DAX to create calculated columns, which will improve compression efficiency and reduce refresh time.
