Hey Ambroise, as far as I know, formulas can’t loop through comma separated values, so we wouldn’t be able to do this and would have to use a script for it

I’m just guessing about your base set up, but I assume that you’ve got:

• Table 1
  
  
  
  • Record 1:
    
    
    
    • Date value: 2022-06-01
      
    
    
    
    
  
  
  • Record 2:
    
    
    
    • Date value: 2022-12-05
      
    
    
    
    
  
  
  
  


• Table 2
  
  
  
  • Record 3:
    
    
    
    • Linked field value: Record 1, Record 2
      
    
    
    • Rollup value: 2022-06-01, 2022-12-05
      
    
    
    
    
  
  
  
  

Any chance we could put the formula that checks whether the date’s after today inside Table 1, and then do a rollup with an IF, like in this base I’ve set up?

Thanks for the pointers, I had simplified the problem voluntarily.

I don’t think automations can help in this case (too many would be triggered at each change), and putting the formula in “Table 1” won’t help, because the formula isn’t actually a simple “is after today” comparison, but a comparison with a date that is specified elsewhere, and looked up in “Table 2”.

I was thinking about using a formula that parses each date distinclty, and checks whether any of those passes the filter (which is “is after today?”, in this example)

Ah got it. Yeah, I don’t think you can loop through comma separated values via a formula, so you wouldn’t be able to parse each date in the rollup I’m afraid

Would love to try to help create a workaround though! If you could let me know what the exact thing we’re trying to do is with the base setup I’d be happy to take a crack at it

Hi,

can you use built-in Rollup filter for your case?
