IFS with condition Result

[alhazen]

Hello,

I need your help.

I have a column called [side] with valid if formula, which is:

IFS(
[winding_type]="Two Winding Transformer",
LIST("HV-Ground","LV-Ground","HV-LV")
)

I tried to combine with this formula, but it doesn't work:

NOT( 
IN( 
[side], 
SELECT( insulation_resistance[side], 
AND( 
[service]=[_THISROW].[service], 
[product]=[_THISROW].[product], 
[time]=[_THISROW].[time], 
[id]<>[_THISROW].[id] 
) 
) 
) 
)

Is it possible to combine those formulas above?  Thank you

An expression in Valid If setting must return either one of a list or a yes/no value and you cannot have both at the same time.

So to make the second expression into a list try

insulation_resistance[side] - SELECT(<< whatever you already have>>)

This (should) gives a list of allowed values rather than invalid values.

Not sure of the exact relations of this with the first expression but I guess it is

IF( //rather than IFS
[winding_type]="Two Winding Transformer",
LIST("HV-Ground","LV-Ground","HV-LV"),
insulation_resistance[side] - SELECT(<< whatever you already have>>) // the above expression as the else value
)
