Min and Max Date between two tables

allejot — Fri, 02 Dec 2022 08:39:56 GMT

Hi guys,

I am pretty new to DAX and I need a little help in solving an issue. Here my situation:

2 tables:

- PROJECT: project ID

- LEDGER LINES: posting date, project id

Desired outcome in table PROJECT: project ID, earlest date, latest date

I basically want to create 2 calculated columns in table project showing me earliest and latest activity in the project. Any help with the formulas I need for these 2 columns? Thanks!!

Hi allejot,

As per your question I have created the below table.

1. Create a new column as

Earliest date = CALCULATE(Min('LEDGER LINES'[posting date]),FILTER('LEDGER LINES','LEDGER LINES'[Project Id]=project[Project id]))

2. Create a new column as

Latest date = CALCULATE(MAX('LEDGER LINES'[posting date]),FILTER('LEDGER LINES','LEDGER LINES'[Project Id]=project[Project id]))

Results:

Hi allejot,

i would recommend creating a relationship between the two tables.

After this you can easily create your columns with the earliest and the latest date.
Therfore create a new column in the Project Table.

EarliesteDate = MINX(RELATEDTABLE('Ledger Lines'), 'Ledger Lines'[PostingDate])

LatestDate = MAXX(RELATEDTABLE('Ledger Lines'), 'Ledger Lines'[PostingDate])

In this solution you are using something wichich is called "Row context". It is a very import thing within DAX.
I hope this will help you.
