PowerApp lookup value from SharePoint List

(0) ShareShare

Posted on by 79

Hi All,

 

I have an app that has a lookup field that i want to have look up another field if the first is blank.

 

Output has the lookup code in it as LookUp('Tracker','Request ID'=Lookup Value 1.Text,OUtput A)

 

 LookUp('Tracker','Request ID'=Lookup Value 1.Text,OUtput A) if Lookup Value 1 is blank LookUp('Tracker','Request ID2'=Lookup Value 2.Text,OUtput A).

 

So two fields to lookup from and output either into the output field

    Hi @Mclean2023 ,

    Try this format

    With(
     {
     _Data:
     Coalesce(
     'Lookup Value 1'.Text,
     'Lookup Value 2'.Text
     )
     },
     LookUp(
     'Tracker',
     'Request ID' = _Data
     ).OutputA
    )

    Hi @Mclean2023 

     

    You code should look like:

    If(
     CountRows(LookUp('Tracker','Request ID'=Lookup Value 1.Text,Output A)) > 0, 
     LookUp('Tracker','Request ID'=Lookup Value 1.Text,Output A),
     LookUp('Tracker','Request ID2'=Lookup Value 2.Text,OUtput A)
    )
