Background documentationCentral Clearing: Posting Logic for Flows

 

When a central counterparty has accepted the clearing of a financial transaction, all flows for that financial transaction and the external account flows (such as margin payments and fees) pass via the clearing account.

The flows from the financial transaction (such as interest flows) are then no longer relevant for payment and are posted using the clearing account as opposed to the bank clearing account.

Payment is made by means of a net payment.

Prerequisites

The documentation on External Accounts describes the settings that you need to make in Customizing so that you can use the functions for central clearing. The same section contains a table of the necessary update types.

In the activity Define Account Determination, you need to create the following posting specifications and assign the posting-relevant update types:

  • 30001 Central Clearing: CCC: Technical Clearing / Bank Clearing

  • 30002 Central Clearing: Bank Clearing / CCC: Technical Clearing

  • 30003 Central Clearing: Position / CCC: Technical Clearing

  • 30004 Central Clearing: CCC: Technical Clearing / Position

  • 30005 Central Clearing: Margin Expense / CCC: Technical Clearing

  • 30006 Central Clearing: CCC: Technical Clearing / Margin Refund

  • 30007 Central Clearing: Fees / CCC: Technical Clearing

  • 30008 Central Clearing: CCC: Technical Clearing / Fees
