Virtual Column as Dropdown with unique values from a specific colum

[PhilippSeidel]

Hi,

i want to use a Virtual Column as Dropdown with unique values from a specific colum but i cant get it to work.

What i did:

• created virtual column
• App formula: empty
• Type: Enum
• Base Type: Text
• Input mode: Dropdown
• Valid if: SELECT(Bereiche[Halle], TRUE,TRUE)
  

The colum is not showing up in my form! What am i missing?

Your problem is that it uses a virtual column.
Virtual columns: THEY CANNOT BE EDITED, their content is ALWAYS the result of your APP FORMULA and is presented in a _Form view only in certain cases.
