Removing from Collection if exists in another collection

(0) ShareShare
ReportReport
Posted on by RicHague 18

Hello,

I have two collections, PlannedVisits and CompletedVisits. What I want to do is remove the visit from the PlannedVisits collection if the visit is in the CompletedVisits collection. Both Collections will have VisitID and LineNumber columns.

 

I've tried using a ForAll on the PlannedVisits collection and then Filter the CompletedVisits collection and tried a RemoveIf with a filter in the condition, with no success.

 

 

I will really appreciate if anyone can let me know how to do this.

 

Thank you

    I think I have worked this out. I can use the ClearCollect to a temporary collection with a filter:

     

    ClearCollect(
        colTemp1,
        Filter(
            colPlannedVisits,
            !(VisitID in colCompletedVisits.VisitID And LINENUM in colCompletedVisits.LINENUM)
        )
    );
    ClearCollect(colPlannedVisits,colTemp1);
    Clear(colTemp1);

     

    This copies the visits that are not in the CompledtedVisits collection. So the visits that are in the both are not copied.
