2. CASA - An Overview

Current Account and Savings Account, commonly referred to as CASA, is one of the modular sub-systems in the Oracle FLEXCUBE system. Through this system your bank can execute the following functions:

• Create a customer account
• Capture details of a Cheque book issued to a customer
• For each Cheque book, the details of which you have maintained, the system generates a status matrix. This matrix stores the status of each leaf of the Cheque book. When no transaction has taken place the status of the Cheque is stored as ‘unused’. Whenever a Cheque based transaction is initiated by Data Entry modules the status of this Cheque moves from ‘unused’ to ‘used’ in this matrix. Subsequently, if a Cheque is canceled or rejected the status can be updated in the status matrix.
• Apart from this, tracking and upholding a stop payment instruction against Cheques, is also a function that this sub-system supports. These stop payment instructions, normally coming from a customer against a Cheque or a series of Cheque or an amount for which a Cheque was issued; are applicable for a period or indefinitely.

Yet another feature supported by CASA is the facility to define amount blocks for accounts (as per a customer’s instruction or the instruction of the bank). The system processes the expiry of such blocks automatically.

To put it briefly in the CASA sub-system you maintain the following details:

• Cheque books issued to customers
• Amount blocks enforced against accounts
• Stop payment instructions issued by customers

These details are maintained in what are called data tables and are called forth for interface during a Cheque processing by the Data Entry system. These tables are:

• ‘Cheque Book Details’, ‘Cheque Status’ and ‘Cheque Details’ where you maintain Cheque book details
• ‘Amount block maintenance’ where you maintain amount blocks against particular amounts
• ‘Stop Payment’ where you maintain stop payment instructions issued against a Cheque or range of Cheques

This chapter contains the following sections:

• Section 2.1, "Major Features"
• Section 2.2, "Major Functions"

2.1 Major Features

There are three major features this system provides:

• A service which returns the status of the Cheque
• A service which updates the status of the Cheque
• A service which will process initiation and expiry of stop payment instructions and amount blocks

2.2 Major Functions

The major functions, which the system provides, are the following:

Function	Details
Maintenance	It provides for maintenance of Cheque books issued for a customer account, with a provision to track and update the status of each Cheque leaf in the book Maintenance of stop payment instructions issued by customers based on, either, Cheque numbers, or, the amount for which the Cheque, or Cheques, were issued A facility to maintain amount blocks on customer accounts
Processing	Whenever a Cheque-based transaction is initiated, the system will alert the user about the status of the Cheque In case of a stop payment instruction enforced against that account number, the system will verify whether the details of the Cheque and the stop payment instructions match. It will warn the user accordingly, and ask for an override In case of amount blocks, the system takes care of the minimum bal­ance to be maintained in the account while monitoring Limits. The system allows the debit transactions initiated from branch over the counter or through inward clearing to utilize the uncollected funds when the transaction amount exceeds the account balance by doing a force debit against the uncollected funds.
Reports	Two types of reports can be generated: Details of all Cheques processed along with their status. Details of stop payment instructions enforced against various accounts. Details of records that have been purged.
Purge	The user has the facility to purge old records which are no longer being used.
