A contract with a customer may be partially within the scope of IFRS 15 and partially within the scope of another standard. In that scenario: [IFRS 15:7]
if other standards specify how to separate and/or initially measure one or more parts of the contract, then those separation and measurement requirements are applied first. The transaction price is then reduced by the amounts that are initially measured under other standards; if no other standard provides guidance on how to separate and/or initially measure one or more parts of the contract, then IFRS 15 will be applied.
