Contract Account 
Structure used to bill the posting data for contracts or contract items for which the same collection/disbursement agreements apply.
Contract accounts are managed on an open item basis within Contract Accounts Receivable and Payable.
In the industry component Insurance, you can decide whether accounting is to be managed
on an account or open item basis.
You can define an alternative
correspondence recipient in the contract account (see
Recipient and Sender
Determination).
You do not have to activate contract account changes to have immediate effect, but rather you can enter a date as from which the changes should become effective. This data is not written to the database but recorded in change documents. The planned changes function only applies to changes to the contract account. You cannot schedule the creation of a contract account.
To activate this data, you should run program BUSPCDACTon a daily basis. This writes the scheduling to the database. You can use the application object FICA to activate planned changes to the contract account.
When you are in display mode for change documents, you can delete inconsistent data, for example, data that arises when planned changes are cancelled.
When you create a contract account, you can add a check digit to the contract account number. The prerequisites are as follows:
· You add the check digit procedure using event 1051. (Sample function module FKK_SAMPLE_1051_2_CHECKDIGITS for two check digits is supplied by SAP)
· The contract account is created with internal number assignment.
· Only procedures with one or two check digits are supported. The number range is configured such that it begins with a leading zero (check digit procedure with one check digit) or with two leading zeros (procedure with two check digits).
You can make enhancements using the Business Data Toolset (BDT) in the menu for transaction CAWM.
Every contract account master record consists of general data that is the same for all business partners assigned to the contract account and business partner-specific data that can be set differently for each business partner in the contract account.
In the industry component Insurance, you can also define this data for the insurance
relationship.
The master data is structured according to the processes that depend on the contract account data, such as incoming and outgoing payments, correspondence, dunning.
All transactions relating to contract accounts access data from the contract account master record (such as payments and dunning). Several transactions change data in the contract account master record (such as payment locks for returns).
