The KFS can be configured to require sales tax information on the selected document types as well as the account and object code combinations. The document types and account/object code combinations are stored in two separate business rules. When an account and object combination in the account and object code parameter is used on a document in the document type parameter, the systems displays the sales tax line after you add the accounting line.
The system does not display the sales tax line until you enter the account and object code and click the add button.
The SALES_TAX_APPLICABLE_DOCUMENT_TYPES parameter defines the document types that this behavior should appear on. The SALES_TAX_APPLICABLE_ACCOUNTS_AND_OBJECT_CODES parameter specifies the account and object code combinations that prompt you to enter sales tax information.
