Hi all,

I'm building an app where I'm first collect a couple of SharePoint list items into a local collection, called "Col_TOBEAPPROVED".

The users can edit this collection inside my app.

When the are done with editing the multiple items, the "Col_TOBEAPPROVED" collection should be patched in to the original SharePoint list ("workregistration").

I was trying to do this with the follow statement, but it is not working:

ForAll(
 Col_TOBEAPPROVED,
 Patch(
 workregistration,
 LookUp(
 workregistration,
 Id = Col_TOBEAPPROVED.ID
 ),
 {
 Approved:Col_TOBEAPPROVED.Approved
 }
 )
 )

If someone of you have a clear solution or idea, I'm open for any suggestion.

Thanks in advance.

If your collection has the same column names (real names) as your datasource, then you need not do all of this, you can simply use the following:

Patch(workregistration, Col_TOBEAPPROVED)

If you need selective column changes instead of the full collection values, then the following:

Patch(workregistration, ForAll(Col_TOBEAPPROVED As _item, { ID: _item.ID Approved: _item.Approved } ) )

ForAll is a function that produces a Table...use it in your Patch and Collect. The Patch and Collect function can handle a full table as its argument and will speed of the performance rather than trying to use ForAll as a For/Loop.

I hope this is helpful for you.

@RandyHayes
What is the easiest way to update the collection after saving the items to SharePoint via the method you described? Patch(workregistration, Col_TOBEAPPROVED)

This will update all existing items in SharePoint and save newly created items. I would like to update the ID column in the collection for the new items, is this possible or do we need to use a forall function instead?

You didn't state what control this expression should be on. Is it the OnSelect property of a button or where?

I have the same scenerio, i created a save button and applied the expression on the OnSelect property of my button and it is not updating my list.
OnSelect = Patch( RCalRebateRate, rateCameroon)
I created a collection on the OnChange property of my Dropdown control. I want to be able to save changes made on the Gallery, spooling that collection to my SharePoint list. Below is expression used to create my
ClearCollect( rateCameroon, Filter( RCalRebateRate, Market = "Cameroon", Band = Dropdown2.Selected.Value ) )
collection

Did you ever figure this out? I'm trying to do the same thing you are to "UPDATE" a record by looping through a collection instead of creating a new one.

Never mind. I figured this out just now.
ForAll(CollectionName, Patch('SharePointList', First(Filter('SharePointList', ID = CollectionName[@ID])) , {Status_Txt:"Delivered"}))

Hi @LoghanRiodan ,

You can use the expression that @StraighterSwing posted above directly in the OnSelect property of a button. The only thing you need to change is your collection and list names and the actual column(s) to be patched.
