Hi @ilimeli,
Could you please tell me that the field type of the 'Solution Rating'?
Do you want to display the last submitted rating value and edit it?
Actually, we create a Text column in data source to store the rating value.
Not sure if there is a form for you to edit the record, I just suggest you add an edit form to display and edit rating value.
1). Add an Edit Form and click on the Rating Data Card at the left side in the tree view.

2). Unlock the Rating _DataCard1as in the below screenshot.


3). Click on Advance of the “Rating Data Card” and replace the ‘DataCardValue2.Text” to “Rating Value. Value” in the “Update” property.

Note that the Default property of the Rating represents the last submitted rating value, I set it as :
ThisItem.'Solution Rating'
4). Set the Edit Form DataSource property as your Dataverse table and set the Item property of the form as below:
First(Sort(DataverseTable,'Modified On',Descending))
5). Add an submit button and set the OnSelect property as below:
SubmitForm(Form1)
