Hi All,
I need your help. I have researched possible solutions on this forum & the wider net, but couldn't find what I'm looking for. Much appreciate any help, pointer, assistance!
Scenario: I have a table with 3 columns, date & closing price & type. This of course links to a date table.
Requirement: I want to obtain the first price information per type against different time periods. Below image shows expected outcome for a 7-day period (column 'starting price', which is ultimately used as input to obtain column 'cumulated gains'):
Objective: using above for context, I want to obtain first value as repeating values for that specific time window (in this case 7-day) as shown in column 'Starting price'. This value is then used to calculate column 'Cumulated gains' from start of each window
what I did so far: I used 'FIRSTDATE' function to obtain the first value. It works fine if only I wanted a card. However, when I plugged this in a more elaborate DAX statement, I get an error (as usual, undescriptive "table of multiple values was supplied where a single value was expected". Ok descriptive, but i have no clue where to begin!). See DAX code below:
Who knows? Probably, I am over complicating what is probably something easy. Hence my turning to you for help.
Looking forward to your assistance & help for pointers to what I'm doing wrong
Thanks
Bare
@Bare one thing is not clear what define the 7 day period. Mon - Sun, sun to mon or something else?

Hi @parry2k
Thanks for having a look.
I define Mon as 1, Sun as 7 per default. In praticse, the time window will be longer in years: 1, 3, & 5 yrs. I used here days for illustrative purposes only.
I've simply left the definition of the time period to the DATEADD function. Hence in the DAX code, I have used a 'nonblank' VAR to get the first non blank date if at the end of DATEADD we have a weekend.
I hope this helps and answers your question
