Calculated column for rank within group

Hi,

I have data including a unique session id, a timestamp for the different events within that session and their names. I would like to create a column that shows the rank of each event within the session, as shown below.

Session_IDTimestampNameRank
122.05.2023 18:00a1
122.05.2023 18:10b2
222.05.2023 18:05b1
222.05.2023 18:07a2

I've tried a couple of different things, but the closest I've come is with this (Overview being the table name):

Rank within Session =
RANKX(
    FILTER(
        'Overview',
        'Overview'[Session_ID]=EARLIER(Overview[Session_ID])
    ),
    'Overview'[Timestamp]
    )
which however gives the overall rank, disregarding session_id.
 
Any help would be greatly appreciated!

Hello @modverre 

 

Use the below Measure to populate the required result.

 

Rank Column =
RANKX(
    FILTER(
        rankkx,
        rankkx[Session_ID] = EARLIER(rankkx[Session_ID]) &&
        (rankkx[Timestamp] < EARLIER(rankkx[Timestamp]) ||
        rankkx[Name] < EARLIER(rankkx[Name]))
    ),
    rankkx[Timestamp],
    ,
    ASC,
    Dense
)
