Hi,

In Canvas app I used to have function OptionSet = Blank() which worked well but suddenly stopped working and now throws error. When I change it to IsBlank(OptionSet) I get delegation warning. Any ideas how to solve this issue?

Hi @PixelWitch,

IsBlank() is nondelegable function, that's why you have delegation warning.

If you have less than 2000 records, please ignore this warning message.

OptionSetValue is a special format value, generally we could not compare it with a text string directly.

We could use Text() function to compare:

Text(OptionSet) = Blank()

Hi,

why was this changed overnight? @microsoft

It does not work inside a filter(), there you still get delegation warning.

Best regards,
