Comprehensive and Detailed 150 to 250 words of Explanation From Workday Record-to-Report/Course Guide/topics:

Before Company B creates an operating lease contract, administrators must establish the relationship among the company's enabled lease type, accounting method, and book code. The Maintain Lease Contract Book Code Configuration task provides this mapping. Workday uses it to determine which accounting basis applies when the lease contract is created and to route generated lease accounting into the correct book code.

Membership in a company hierarchy is not a prerequisite for entering a lease. A standalone legal entity can maintain its own lease configuration and accounting books. Approval of unrelated supplier contracts does not supply the required accounting mapping. Option C reverses the sequence: users should not manually choose an arbitrary lease type, method, and book code on the first contract before the governing configuration exists. Where multiple lease-accounting options are enabled, Workday specifically requires distinct lease contract book code configurations and prevents incompatible codes from being reused across standards. Once the configuration is complete, Company B can create the supplier contract using the appropriate lease contract type, and Workday can generate initial recognition, installments, expense recognition, and multibook accounting consistently. Therefore, Maintain Lease Contract Book Code Configuration is the required setup action.
