Cumulative Count for Order/Index

[Anonymous]

Hey guys, how are you?

I'm struggling to try to calculate a cumulative sum in a table, in order to create a sort of index or order for projects.

Let's say I have a database related to projects where any change I made to the project, a new key is generated related to that project.

So the structure is like:

The Project Code field could be repeated as many times as possible and the KEY field is a register in de database which creates a new one every time a change is made to the project, so KEY could not be repeated.

What I need to do is to create a CUMULATIVE COUNT of the Key column, for every Project Code.

Thank you!

Hi @Anonymous

can you provide a sample data model and what the expected output would look like?

You can use a calculated column like

Index =
RANKX (
    FILTER ( Table1, [Project Code] = EARLIER ( [Project Code] ) ),
    [Key],
    ,
    ASC,
    DENSE
)

THANK YOU! I didn't know the RANKX function!

All I have learned is from Youtube and self-working.

Thank you!
