Answer
When specifying Item.ItemCompatibilityList in ReviseItem call, you are adding additional compatibilities to the existing ones. The item in question has 169 compatibilities ( using GetItem call to check ItemCompatibilityCount tag ) and you are providing 198 more fitments in your ReviseItem request hence the error.
