Patch new record and update existing record

Posted on by Community Power Pla...

Hi everyone.

I have a SharePoint list to check if a person submit a form on which category (product/competitor product/manager verification).

Whenever user submit a form (this form will store the record in another list, not in this list), PowerApps will check whether the form is submitted under which category and update "1" in this list (above picture). I have made dropdown list to determine this category that have 3 choice (product/competitor product/manager verification).

I tried used below patch function, but it creates new record instead of update the column inthe existing record (refer to sarah's record in the picture).

If(DataCardValue3.Selected.Value = "Competitor",
Patch('List Name',
Defaults('List Name'),
{
Title: DataCardValue7.Text,
Month: DataCardValue4.Text,
Year: DataCardValue12.Text,
'Competitor Product': "1"

}));

If(DataCardValue3.Selected.Value = "Our products",
Patch('List Name',
Defaults('List Name'),
{ Title: DataCardValue7.Text,
Month: DataCardValue4.Text,
Year: DataCardValue12.Text,
'Product': "1"

}));

How can I capture whether user submit new record or already have existing record? I know I cannot used the "defaults" on both patch, but don't know how to start.

If new record, it will patch and create new record.

If existing record, it will patch/update the column in existing record.

Thank you in advance!

My code below will show you how its done. You can apply a similar concept to your other code segment.

// try to find the record and store it in a variable if it exists Set(lookupRecord, LookUp(Title: DataCardValue7.Text, Month: DataCardValue4.Text, Year: DataCardValue12.Text,)); If( // if no record exists create a new one DataCardValue3.Selected.Value = "Competitor" And IsBlank(lookupRecord), Patch( 'List Name', Defaults('List Name'), { Title: DataCardValue7.Text, Month: DataCardValue4.Text, Year: DataCardValue12.Text, 'Competitor Product': "1" } ), //if the record exists update instead DataCardValue3.Selected.Value = "Competitor" And IsBlank(lookupRecord), Patch('List Name', lookupRecord, 'Competitor Product': "1") );

I'm newbies for PowerApps, please advice.

I follow your solution above on my app, I found error when type LookUp(Title:DataCardValue2.Text) same as your.

Here are my questions:
1. why my code below shown error while your sample code did not?
2. Refer to above reference, LookUp usually follow with source. is this exceptional case that no data source required?

3. when I insert my data source, I still found error also.

please advice, thank you

Lookup('DataSource',Title=DataCardValue2.Text)

Kind regards
