Lookup formula cannot be evaluated remotely due to service limitations...

Lookup formula cannot be evaluated remotely due to service limitations.. The local evaluation may produce suboptimal or partial results. If possibel please simplify the formula..

 

Getting this error based on the following formula:

 

Distinct(Filter(dsrDataSource,Left(Location,3)="020" && Carline="TOTAL"),Left(Location,3))

 

Left(Location, 3)="020" is underlined in blue. Not complicated at all. I am getting results, but I don't know if they are accurate.

 

Any ideas?

    Hi @Hockeyman9474,

     

    This should be caused by delegation.

    Understand delegation

    And the function you used here (left() ) is not under the delegatable function list.

    Please read the article above for more details.

    For a workaround, replace the left(location,3)="020" with startswith function.

    StartsWith function in PowerApps

    StartsWith(Location, "020")

    The whole formula should be:

    Distinct(Filter(dsrDataSource,
     StartsWith(Location,"020") , 
     Carline="TOTAL"),
     Left(Location,3))

    There is no need to add && within the filter function, Multiple expression would be in an and condition by default.

    Check to see if this would make it work.

    Regards,

    Michael
