## Data Modelling

My data would have 2 columns names "Posting Date" and "Name" as listed below.

The third column should be generated through a formula with the below condition.

For every name, for every date, a value of 8.5 should be shown only once in the third column.

Is there an formula to generate this in Excel and DAX in PowerBI?

1) add an index column in PQ:

2) create a column with this:

Column = IF(MOD([Index],2)=1,8.5)

i tried and it worked like this:

Hey hi,

Thanks for the response.

My data is very simple but large. It will have "n" number of Date entries for a single day as the NAMES are 100+.

Also one person can have multiple entries for a day too.

For eg, If there are 100 resources & 2 entries per resource per day, there are 200 entries per day and for a year there will be 200*365 = Approx 73000 entries.

But the value 8.5, I should get it only for one resource per day, so 100 entries and 365 days do 100*365 = 36500 entries as "8.5".

Hope I'm clear in my explanation.

The sample needs to be representative enough. Try to enrich your sample by

1) including a unique column you already have, otherwise an index column is suggested.

2) increasing the complexity, showing how "one person can have multiple entries for a day"

p.s. 73000 is not a big number.

Thanks let me try.

73000 was just an example. The actual counts to 1 Million which still might not be a big number to you 😄
