Why is this an issue?

There is no reason to re-assign a variable to itself. Either this statement is redundant and should be removed, or the re-assignment is a mistake and some other value or variable was intended for the assignment instead.

Code examples

Noncompliant code example

  name = name ' Noncompliant
End Sub

  Me.name = name ' Compliant
End Sub
