How to only return values where string isn't available in a column

(0) ShareShare
ReportReport
Posted on by Community Power Pla... Microsoft Employee

I have a Gallery that will display Appointments to select from. The issue is, within the Appointment Entity, we also have a number of automated appointments that should not be visible to users to select.

 

I have tried using Filter(Appointments, Not(IsMatch(subject, "PAW")))

 

But i get the error that the expression can't be evaluated remotely.

I do not know how else to write the statement so any help would be great.

 

Thanks in advance

    As far as I understand it correctly, it's not an error, this suggestion that formula contains something that cannot be delegated.

    If you have SQL Server data source, try to use:

    Filter(Appointments, Not("PAW" in subject))

    If you have other data source, there is no way to solve this with delegation supporting.

     

    Look at this article about delegation:

    Hi @Anonymous,

     

    Just as told by @Oleks, this is related to delegation.

    Check more details about delegation in the following article:

    Understand delegation

    Tired with the solution provided, it would work under Dynamics 365 appointments entity, no remidnings for the delegation.
