Pull from a table the first transaction based on a date column.

I have a transaction table(A) with 4 columns say X, Y, Value and Date. I want to create a new table(B) from Table A such that Table B have unique transactions(rows) based on the combination of X and Y columns, and should pick only first transaction based on the date column. For example - 

Table A:

XYValueDate
X1Y1111-11-2022
X1Y1214-11-2022
X2Y2413-11-2022

 

Table B: It should only have one row for X1 and Y1 combination for date: 11-11-2022 as it is the first trasaction. 

XYValueDate
X1Y1111-11-2022
X2Y2413-11-2022

 

Thanks in advance.

Hi  @mak_tushar ,

 

Here are the steps you can follow:

1. Create calculated column.

Table 2 =
CALENDAR(
    MIN('Table'[Invoice Date]),MAX('Table'[Invoice Date]))

2. Create measure.

Flag =
var _select=SELECTEDVALUE('Table 2'[Date])
return
IF(
    MAX('Table'[Invoice Date])=
MINX(FILTER(ALL('Table'),'Table'[X]=MAX('Table'[X])&&'Table'[Y]=MAX('Table'[Y])&&'Table'[Location]=MAX('Table'[Location])&&'Table'[Invoice Date]>=_select),[Invoice Date]),1,0)

3. Place [Flag]in Filters, set is=1, apply filter.

This is part of the previous one. Actually Table A has data for past 3 years and I want to have data only after 1 Feb in the new table. -

Try to create a new table with the code below:

B =

ADDCOLUMNS(

   SUMMARIZE (

       A,

       A[X],

       A[Y],

       A[Value]

    ) ,

   "Date",

   CALCULATE (MIN(A[Date]))

)

Is there a way to apply filter on the date as well? I want to pull records from table A that have invoice date greater than 1 feb.

is it a new requirement or in addition to the previous one?Or could you elaborate the expected table in Excel?

Then try this:

B =

CALCULATETABLE(

ADDCOLUMNS(

   SUMMARIZE (

       A,

       A[X],

       A[Y],

       A[Value]

    ) ,

   "Date",

   CALCULATE (MIN(A[Date]))

),

A[Date]>DATE(2022,1,1)

)

Getting duplicate rows (based on X and Y column).

 

how does the issue look like?

Is it an issue, considering you have different data in column Value and Date?

First two rows are duplicate as the first three coulmn values are same. Form these two(duplicate) rows, I want only the first row in my table as it has an older date.
