DAX - POWER PIVOT measures using date before date

PaulStokes — Tue, 20 Feb 2024 12:45:24 GMT

Hello fellow DAX enthusiasts,

Help needed please.

I can do this simply in Ms Excel. But I am struggling to write the DAX to have as measures in a Power Pivot in Excel.

Sample data below drawn from Table named PriceData. PriceData data-model is joined to Tbl_Dates (calendar 2023)

Please advise how I can write a measure to get EarlyDate and EarlyValue.

Thanks in advance

PART	SUP_NAME	DATE	Cost	EarlyDate	EarlyValue	% Change
ABC	Test123	22/06/2023	1.5044
ABC	Test123	21/07/2023	1.5044	22/06/2023	1.5044	0.0%
ABC	Test123	29/08/2023	1.5044	21/07/2023	1.5044	0.0%
ABC	Test123	18/09/2023	3.625	29/08/2023	1.5044	141.0%
ABC	Test123	03/10/2023	1.5088	18/09/2023	3.625	-58.4%
ABC	Test123	24/10/2023	1.6244	03/10/2023	1.5088	7.7%

Hi PaulStokes possible solution as following

create 3 different calculated columns as you are calculating amounts based on row level

Creation order is important to avoid complexity. Output below is the same as your picture

1. EarlyDate

=
VAR __part=MyTable[PART]
VAR __sup_name=MyTable[SUP_NAME]
VAR __date=MyTable[DATE]
RETURN
CALCULATE(
MAX(MyTable[DATE]);
FILTER(MyTable;MyTable[PART]=__part && MyTable[SUP_NAME]=__sup_name && MyTable[DATE]<__date)
)

2. EarlyValue

=VAR __part=MyTable[PART]
VAR __sup_name=MyTable[SUP_NAME]
VAR __date_early=MyTable[EarlyDate]
RETURN
CALCULATE(
SUM(MyTable[Cost]);
FILTER(MyTable;MyTable[PART]=__part && MyTable[SUP_NAME]=__sup_name && MyTable[DATE]=__date_early)
)

3.% Change

=
IF(MyTable[EarlyValue]=BLANK();BLANK();
MyTable[Cost]/MyTable[EarlyValue]-1)
