Patch combobox to multiple choice column in sharepoint list

(0) Share

Report

Posted on by luwu_7100

Hello together,

I want to create new entries in my sharepoint list (List1) by using a powerapps page. For one column I have a ComboBox in powerapps because I need the possibility to patch one or more choices. In my sharepoint list multiple selection is allowed.

My code:

Patch(

List1;

Defaults(

List1

);

{Column1: ComboBox1.SelectedItems}

)

I get the error message "missing colums. In your formula is missing a column "value" from type "text" and "invalid argument type. a table value is expected but with a different schema".

In my formula I have some more columns to patch, but just with textinput. These are working fine if I try without the combobox column.

Can anybody help me here?

Thanks in advance

Lukas

Hi @luwu_7100 ,

The multi-select column of SP list needs the table with the column name "Value", and your Items gets the table with the column name "Teilkreis", so we only need to change the column name to "Value".

Hi @luwu_7100 ,

Please try this:
1.Modify the code on the Items:
RenameColumns(Teilkreis[@Teilkreis],"Teilkreis","Value")
2.Then use the above patch formula:
Patch(List,Defaults(List),{ReqiuredColumnName:"test",ChoiceColumnName:ComboBox.SelectedItems})

Hi @v-mengmli-msft ,

items are defined by an excel list that is connected to my powerapp, where all possible expressions are listed.
So items of my combobox is "Teilkreis[@Teilkreis]" ("Teilkreis" is the name of the table and of the column in excel).
To make sure that this is no problem I enabled the option where I can allow to manually add new values in my sharepoint list.

Thank you
Lukas

Hi @luwu_7100,
Please make sure when you patch your data to the SharePoint list, you include any columns that are set to required.

Here is an example of patching different column types to SharePoint.

Patch( 'Test List', Defaults('Test List'), { testText: TextInput1.Text, // Text column testNumber: Value(TextInput1_1.Text), // Number column testChoice: ComboBox1.Selected, // Single value choice column testMultipleChoice: ComboBox1_1.SelectedItems // Multiple value choice coulmn } )

Please note: You will need to change the code to suit your language locale.

Also 'Allow multiple selections' should be set to yes in the SharePoint column.

Please tick Accept as solution if the answer is useful.
Thanks,
@AARON_C
