A multi-select field inside of a collection: how to patch the data back to a list?

Hello. I have built a PowerApp canvas app that allows the user to easily enter near-duplicate data records and store them temporarily in a shopping cart (BadgeRequests).  The shopping cart is really an in-memory collection of the data. When the user has entered all of the items that she needs, she will click the "Submit All" button to save the shopping cart to the SharePoint list. Additionally, each badge request could have multiple clearances chosen.  Here is a screenshot to illustrate:

That is the MyClearances field which is a LOOKUP on the Clearances list. It is setup to allow the user to select one or more items.

 

Like I said this data is stored in a collection so that the user can submit them all-at-once. Or they can choose to cancel and none of the records will get patched.  Here is a screenshot of the collection.

I have been able to figure out how to patch most of the fields back into the list.  But, I have hit a road-block on this multi-select field, MyClearances. I am having difficulty trying to get that data patched back to the list.  Here is the code that I am using. These are the simple fields for me to patch.  However, I cannot figure out how to patch the multiselect field.

ForAll(collect_NonTypBadg,
    Patch(NonTypicalBadges, 
        Defaults(NonTypicalBadges), 
        {BadgeType:collect_NonTypBadg[@BadgeType], 
            BusinessReason:collect_NonTypBadg[@BusinessReason], 
            Comments:collect_NonTypBadg[@Comments],
            Company:collect_NonTypBadg[@Company], 
            DateNeeded:collect_NonTypBadg[@DateNeeded],
            FirstName:collect_NonTypBadg[@FirstName], 
            LastName:collect_NonTypBadg[@LastName], 
            DateExpires:collect_NonTypBadg[@DateExpires],
            PictureNeeded:collect_NonTypBadg[@PictureNeeded],
            RequestStatus:collect_NonTypBadg[@RequestStatus],
            SupervisorAE:collect_NonTypBadg[@SupervisorAE],
            Title:Concatenate("New badge request for ",collect_NonTypBadg[@FirstName]," ",collect_NonTypBadg[@LastName]),
            PicURL_text:collect_NonTypBadg[@PicURL_text],
            PrimaryLocation:collect_NonTypBadg[@PrimaryLocation]
        }
    )
);

 

I have tried a loop inside of the main forall() loop, but it keeps giving me errors on the syntax.  Is there a good way to do this?

Thanks in advance.  --Rick

Hi @ricteel ,

 

I did a simple demo for you.

vxiaochenmsft_1-1631238844379.png

Add a button control and set its onselect property to:

 

ClearCollect(Col,{ColTitle:1,ColLookup:Table({Id:1,Value:"A"},{Id:3,Value:"C"})},{ColTitle:2,ColLookup:Table({Id:2,Value:"B"},{Id:5,Value:"E"})})

vxiaochenmsft_4-1631238893796.png

 

Add another button control and set its onselect property to:

 

ForAll(Col,Patch(LIST167,Defaults(LIST167),{Title:ColTitle,My_Lookup_to_LIST166:ColLookup}))

 

 

The result is as follows:

Thanks @zmansuri   That looks like a really good resource!  I have bookmarked it for future reference and I am sure I will visit it often.

 

However, the closest example I could find in that blog was to patch multiple choices directly from a combo-box.  That is a pretty easy task and I have done that often. 

Patch(
    'Painting Jobs',
    LookUp('Painting Jobs', ID=1),
    {
        ColorsChoice: ComboBox_Colors.SelectedItems
    }
)

My issue is a little different in that I am patching from a collection that contains a multi-selection field.

Hello Wearsky,  This is it!  Thank you so much for taking the time to build out a sample for me.  I really appreciate it... that fits perfectly to my style of learning (poor reading skills and easily distracted) 🙂

This is exactly what i needed.  Thanks again.  --Rick
