## How to calculate fist occurrence

Hi all

I need your help/advice on how to calculate "Result-first export date" from table below.

Basically, For each ID on each row, it should first check through column "Export/Import" and find "EXP" and then return the minimum export date from "Date" column in the result column. Say for example: For ID= A12, first should find where is the EXP located under "Export/Import", it's on row#3&8, so the minimum Export date is on row#8, now it should fill in 3/2/2018 for all the rows that are related to ID=A12.

 # ID Export/Import Date Result- First export date 1 C11 IMP 1/1/2018 5/2/2018 2 B12 IMP 2/1/2019 2/1/2019 3 A12 EXP 4/10/2022 3/2/2018 4 A12 IMP 1/1/2018 3/2/2018 5 B12 EXP 2/1/2019 2/1/2019 6 A12 IMP 2/1/2018 3/2/2018 7 C11 EXP 5/2/2018 5/2/2018 8 A12 EXP 3/2/2018 3/2/2018 9 A12 IMP 3/11/2018 3/2/2018

I kindly appreciate your time and effort here.

Hi @Sanaz ,

Check the formula.

``Column = CALCULATE(MIN('Table'[Date]),FILTER(ALLEXCEPT('Table','Table'[ID]),'Table'[Export/Import]="EXP"))``

Hi Sanaz,

You can make a calculated table and relate it to this table by "ID", see screenshot below.
DAX for calculated table ("Table" is original table, "MinDate" is calculated table):

MinDate =

GROUPBY(

FILTER(

'Table',

'Table'[Export/Import] = "EXP"

),

'Table'[ID],

'Table'[Export/Import],

"FirstExpDate" ,

MINX(

CURRENTGROUP(),

[Date]
)

)
