You can enter an amount in the Amount field, which is to be levied for each counter. If the resultant charge is less than the minimum amount, then the customer is billed with the amount entered in the minimum amount field. Similarly, you can restrict the charge per counter using a maximum amount.

You can use the divisor field to represent the amount as part of the smallest currency unit.

You can set the amount counter indicator if you want to add and post amounts, such as postage costs, rather than the number of units. The external counter amounts must be transferred from the application. If you set the indicator, then you cannot make an entry in the Amount field.

In the free items field, you can define a specific number of free items for which no charges are levied during a billing period.

In the field Maximum Number of Items , you enter the maximum number of items for which charges are applicable in a billing period. The system first takes all free items into account. The system uses Maximum Number of Items on the remaining items.

You can enter a payment currency that differs from the condition currency, which is then valid for all amount fields of the charge condition if no condition currency exists. If both currencies exist, then the condition currency is valid.

You can define tiered- or interval calculation if you have not set the amount counter indicator. A tier or interval starts after the defined number of items. For each tier or interval, you can enter an amount , as well as a minimum amount , maximum amount , and divisor .

If the condition is a markup condition, you can also use a tiered or interval calculation. For absolute markup, the Amount and Divisor field is available, the Percentage field is available for relative markup. For more information, see Markup Condition .

You can define tiers for condition determination if it is not a markup condition. For more information, see Editing the Condition Determination Tab Page .
