How to configure "update file properties"?

[officerNugget]

I have currently a functioning approval flow implemented in Sharepoint. Approval can be sent to one or more people in the company. However, I would like to include in the flow that once approval is done, the sharepoint list column "Approved by" is automatically updated for the item.

This works great if the approval is done by one person. But if the file is to be approved by several person, the field is automatically updated only with the person who first approved the file.

Any ideas how to configure the flow so that the properties for "Approved by" are updated with all the people the approval was sent to?

Hi @officerNugget ,

The reason for this problem is that when the name of the approver is obtained, the flow will add apply to each to traverse the approval responses.

Each time the traversal is performed, the update item will be run once, so the result can only return the name of one approver. 

A string variable can be created to hold the approver name, and each time apply to each is traversed, the Append to string variable adds an approver name to the string. 

Best Regards,
