Saving to SharePoint Managed Metadata columns using Patch function


This is a continuation of the 'Building PowerApps from Scratch? Use Patch!' blog. This blog shows you how you can use the Patch function to save to a SharePoint Metadata column in a list.


SharePoint list

In this example I have a simple SharePoint list which has the following two columns




The Managed Metadata column is connected to the Taxonomy Term Store.





Here is a video which walks you through how the Patch function was used in the PowerApp to save the item.



Here is the formula to save the selected item to the Managed Metadata column


    'TermGuid': DataCardValue.Selected.TermGuid,
    'WssId': DataCardValue.Selected.WssId,
    'Label': DataCardValue.Selected.Label,
    'Value': DataCardValue.Selected.Value


For this formula to work successfully PROVIDE ALL THE VALUES.

Here is the final Patch formula


Patch(ManagedMetadataTest,Defaults(ManagedMetadataTest),{Title: DataCardValue1.Text,
    'TermGuid': DataCardValue2.Selected.TermGuid,
    'WssId': DataCardValue2.Selected.WssId,
    'Label': DataCardValue2.Selected.Label,
    'Value': DataCardValue2.Selected.Value

So all that’s left is the ability to save attachments to a SharePoint list. Once that is possible, PowerApps will be a fully functional and very versatile product to build customized forms built into SharePoint Online or as an App using PowerApps website or mobile app.


Thank you very much! Great example and good explaination.

@darogaelThank you, excellent work. Is there a similar way to do permissions in Sharepoint lists and libraries or do we still have to use App Add-ins and Flow?

Hi, first of all thanks for the info.

I try to figure out how to update a managed metadata column which allows multiple values via the patch function.

Any idea?



I have an issue to get SharePoint Meta Data Column values. Could you clarify more on the default drop down combo is there any customization on the properties to show the meta data as in my case it can't be retrieved in the drop down and I got error ''the function choices has some invalid arguments".



When I use your code I get an error when I put the comma after Patch('Managed Metadata Test', on the comma i get an error:Unexpected characters. Characters are used in the formula in an unexpected way. I think I'm doing something wrong.


May you please assist
