Lease Accounting Engine 
The Lease Accounting Engine is responsible for incoming administration of leases in Accounting. In Customizing, you have defined how the system processes the values for the lease transferred from mySAP CRM in Accounting in the R/3 System.
As soon as a new lease is created in the CRM system (NEWL process) or a change process (for example, BLEX process) is carried out for a lease in the CRM system, mySAP CRM automatically transfers the contract data to the Lease Accounting Engine in the SAP R/3 system.
Using the value identifiers defined in Customizing, the Lease Accounting Engine automatically determines the values from the CRM contract that are to be forwarded to Accounting.
The Lease Accounting Engine then uses these values to classify the lease. In other words, the contract is checked to determine the type of lease involved (capital lease or operating lease). Leases are classified on the basis of verification rules defined in Customizing.
Depending on the result of the classification, the Lease Accounting Engine automatically carries out postings in the Asset Accounting, Accrual Engine, and One-Time Postings applications.

Since these processes run automatically, all of the contract constellations and accounting principles have to be planned and included in the configuration from the outset.
