Hi Steve,You helped me with this topic a while ago.Now how can I do the same with another table? That it be possible to do the two validations at the same column.That is, it is not allowed to enter a code that exists in another tableThanks.

Hello, This is another way in Valid If, of the table where you´re capturing the informationORDERBY(Table[id], [Column])

Thanks a lot @Steve It works perfect!

Hi @Steve I have a similar case. How can I concatenate information from related tables into a virtual column? For example here I want to concatenate two dates from the REGISTRATION table. Thanks! USER ID NAME PHONE VIRTUAL_COLUMN (CONCATENATED DATES)...

Steve, Thanks a lot! it’s working perfectly. I just added a parenthesis. I share the result: OR( ("NO CODE" = [CODE]), ISBLANK( FILTER( "USER", AND( ([CODE] = [_THISROW].[CODE]), ([_ROWNUMBER] <> [_THISROW].[_ROWNUMBER]) ) ) ) )
