Hi Recke,
The partner function is defined in two places within the configuration. One is the default partner function which is as below. This partner function is what flows automatically when you don't enter anything while creating the Condition record.
The other is the partner function function-medium combination which are allowed. If this combination is not maintained , say in your case it is not maintained for SH and 1/5 , then it will give you an information message
