One-Time Postings 
One-time postings allow you to allocate and post a variety of charges and adjustments on a one-off basis. This function also offers you considerable flexibility when choosing accounts. Depending on how the one-time postings are used to solve business problems, you may need to assign accounts according to different information.
You can configure the system in such a way that one-time postings are created automatically when a lease is released or when follow-on processes are carried out. The system then uses value identifiers to calculate the amounts to be posted.
You have configured the following settings in Customizing:
Financial Accounting ® Lease Accounting ® Specifications for Controlling Processing ® One-Time Postings:
® Number Range Maintenance for One-Time Postings
® Specify Value Transfer to Basis Structure for Account Determination
® Specify Account Determination Rules for One-Time Postings
® Group and Summarize Line Items
® Define Posting Control
® Assign Values for One-Time Posting
® Define Account Determination for One-Time Postings
Based on the value identifiers defined in Customizing, the system derives a determination strategy to identify, assign, and post the one-time postings.
The one-time postings application extracts the following information from the data transferred from the lease:
· Process
· Accounting principle
· Document group
· Account determination rule
· Amount to be posted
The system determines which one-time postings are to be made and which accounts are to be used from the assignment of value identifiers to account determination rules and document groups in Customizing.
For more information about the determination
principle, see
Validation,
Substitution, and Rules.

Account determination cannot be configured for specific processes.
Possible one-time postings:
IDC, Initial Direct Cost: Posted once for incidental acquisition costs relating to operating leases.
CORROREV: Correction of the OREV schedule if the contract is terminated prematurely in the middle of the period.
CHARGE: Charges levied for termination of contracts (for all termination processes, that is, for contracts that are terminated prematurely and those that are terminated normally at the end of the contract term).
