## 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:

 X Y Value Date X1 Y1 1 11-11-2022 X1 Y1 2 14-11-2022 X2 Y2 4 13-11-2022

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

 X Y Value Date X1 Y1 1 11-11-2022 X2 Y2 4 13-11-2022

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.

4. Result:

Best Regards,

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. -

Super User

Try to create a new table with the code below:

B =

SUMMARIZE (

A,

A[X],

A[Y],

A[Value]

) ,

"Date",

CALCULATE (MIN(A[Date]))

)

Regular Visitor

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.

Super User

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(

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).

Super User

how does the issue look like?

Super User

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

Regular Visitor

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.
