Helper IIWhy does my VAR function return other values for newly created columns?
Dear all,
I need help,Why does my VAR function return other values for newly created columns?
I would like to create new columns about entry times as shown in the green box.
Find the latest entry time before the current line, if this time and the entry time difference of 2min, then return to the earlier one; if the difference is more than 2min and there is no earlier time, then return to the entry time of the current line.
But why is it that there in the red box, I'm returning a new never-before-seen time?
This is the DAX function for my new column:
pls try this and add the similar coding in red in your original DAX.
Column =VAR _last=maxx(FILTER('Table','Table'[number]=EARLIER('Table'[number])&&'Table'[entry time]<EARLIER('Table'[entry time])),'Table'[entry time])return if (ISBLANK(_last),'Table'[entry time],_last)

YumikangOh thank you,My original sheet looked like this.
I found a time of 11:04:28
But I find that it shouldn't be calculated that way.
The VAR function calculation just mentioned should be performed only when the green module “number” column is the same.
Otherwise it will match the time of the other “number”.
How can I change the previous function?- ryan_mayu
