In the S/4HANA Public Cloud, as a customer you may sometimes need to know what the supported key field combinations are, for various pricing conditions, and furthermore know what the access sequences are (i.e the sequence in which the system tries to find a valid pricing condition).

Maintaining an incorrect key field combination may yield an error message, or you could find yourself retrieving a price (rate) that you do not understand how it was determined when several combinations of a pricing record have been maintained.
To this end SAP has delivered note 2332748 – S/4HANA Supported combinations of key fields for price conditions that should help to demystify this.
