Hi @JimmyWork ,
Do you want to compare User().FullName with a person column value in sharepoint list?
Does your person field allow multiple person choice?
You just need to use formula like this:
Filter(table,User().FullName='Assigned To'.DisplayName)
I know you are worried about the letter case of User().FullName and DisplayName in person field.
Don't worry, these two's value are the same.
Although these two value comes from different places, one from powerapps, one from sharepoint.
But actually their data source is the same.
These two names all come from your Office365 profile.
If you are still worried about this, you could check the DisplayName of 'Assigned To' in your app directly.
For example:
Insert a combo box, set the combo box's Items:
Choices(listname.'Assigned To')
Set the combo box's primary text to DisplayName.
Then you could search yourself in the combo box, the combo box will display your DisplayName.
Insert another label, set its Text to :User().FullName .
Then compare the value displaying in the combo box and the label. I believe they are the same.
Best regards,
