How to merge Patch function in powerapps

[kharina]

Hi All, 

Based from Microsoft Docs ,

Merge records

Patch( Record1, Record2 [, …] )

• Record(s) - Required. At least two records that you want to merge. Records are processed in order from the beginning of the argument list to the end, with later property values overriding earlier ones.

=============

 If my:

1.)  Record1 = is the customized canvass  that I created on Screen1

2.) Record2 = is the edit form on Screen2 (came from SharepointList1)

Question: How can I use the Patch function back to SharepointList1 and merge the data from both Record(s) ?

Merge function is to merge two records outside of a data source, which means to merge the different columns into a record and return a record, If two records contain the same column but different value, it will take the value of the record at the back.

The example:

Formula: Patch( { Name: "James", Score: 90 }, { Name: "Jim", Passed: true } )

Result: { Name: "Jim", Score: 90, Passed: true }

To your question, you have the ensure all columns of two records are from the sharepoint list, then try the following codes.

Patch('SP list', First('SP list'),Patch(Record1,Record2))
