1.6.2.1 Interest Rule Application Factors

The conditions for the application of an interest rule can be defined in the ICCB Rule Details screen.

The rule can be applied to any contract, irrespective of the currency of the contract, the customer and the branch involved. This is referred to as a general interest rule. You must define a general interest rule that would be applicable for any contracts in any currencies, involving any customers, customer groups or branches, before you define rules applicable to specific customers and contracts in specific currencies and in specific branches. The general rule can only be maintained at the head office branch.

Thus, the most general application of the condition can be that it is applicable to contracts in any currency and involving any customer.

After defining the general interest rule, you can then proceed to define rules that can be applied to contracts involving the following specific combinations:

• A specific branch, customer category, customer and currency
• A specific branch, customer category, customer and all currencies
• A specific branch, customer category, currency and all customers
• A specific branch, currency and all customer categories and customers
• A specific branch, customer categories and all currencies and customers
• A specific branch and all customer categories, customers and currencies
• A specific customer category, customer, currency, and all branches
• A specific customer category, customer and all currencies and branches
• A specific customer category, currency and all customers and branches
• A specific currency and all customer categories, customers and branches
• A specific customer category and all customers, currencies and branches
• All branches, customer categories, customers and currencies

Note:

As mentioned earlier, the rules applicable for combinations involving all branches (the ALL option in the Branch Code field) can be maintained only from the head office branch.

Once an Interest Rule has been defined, you must create an Interest Class for the Interest Rule. Creating an interest class for every Interest Rule is mandatory. The details specified for Interest Class is then defaulted to the product you define.

The definition of a product should ideally be preceded by the definition of all Interest Rules applicable to the product. If not, the product definition has to be put on hold, the Interest Rules defined, and then the product linked to the Interest Rules.

Transaction Currency

If you wish to define the attributes for all currencies, you can select the ALL option in the Currency Code field to indicate this. If you are maintaining the attributes for the selected ICCB rule in specific currency other than the ALL, select the Transaction Currency on which the rule mapping maintenance is to be made applicable.

Customer Group

Select the customer group on which the rule mapping maintenance is to be made applicable. You can create a generalized interest rule mapping record by selecting the ALL option in the Customer Group field. This specification defaults to the Customer and Customer Account fields. You are forbidden to change the specification.

Customer

Specify the customer id (CIF) of the customer for whom you are maintaining the rule mapping.

Branch Code

If you are maintaining the attributes for the selected ICCB rule from the head office branch, you can select the branch for which the attributes are being defined. If you wish to define the attributes for all branches, you can select the ALL option in the Branch Code field to indicate this.

If you are maintaining the attributes for the selected ICCB rule from a branch other than the head office, you can only select those branches that are found in the allowed list of branches for:

• the ICCB rule definition Restriction Type (ICCBRULE), in the Common Branch Restrictions maintenance for the current branch
• the selected rule being built, according to the ICCB Rule Availability maintenance

In other words, the option list in the Branch Code field would display only those branches that are allowed both for the rule and the current branch.

The following example illustrates how the option lists in the Rule ID and Branch Code fields are populated: For example, you have created the following Common Branch Restrictions for the restriction type ICCBRULE:

Table 1-7 Branch and Allowed Branches

Home Branch	Allowed Branches
001	000, 001, 002, 005
001	001, 006
002	002, 005, 006
005	002, 005, 006

You have maintained the following rules in the ICCB Rule Branch Availability Maintenance:

Table 1-8 Rule ID and Allowed Branches

Rule ID	Allowed Branches
INTRULE1	000, 001, 002, 005
INTRULE2	001, 005, 006
INTRULE3	002, 005, 006
INTRULE4	002, 005, 006

In the ICCB Rule Details screen, the following options would result if the maintenance were as mentioned above:

Table 1-9 Rules and Branch Code Option List

Branch	Rule ID field option list	Branch Code option list
000	INTRULE1	000, 001, 002, 005
001	INTRULE1, INTRULE2	001, 006
002	INTRULE1, INTRULE3	000, 001, 002, 005, 006 (for INTRULE1) or 002, 005, 006 (for INTRULE3)
005	INTRULE1, INTRULE2, INTRULE3	000, 001, 002, 005, 006 (for INTRULE1), 001, 005, 006 (for INTRULE2) or 002, 005, 006 (for INTRULE3)
