Abstract: The invention is directed to a computer-based method performed in a first transaction-tax-related application. The method comprises exchanging transaction-related data with at least a second transaction-tax-related application according to a standardized transaction-tax interface data model. The invention is also directed to another computer-based method and a related data record, a related software interface, a related computer-based data warehouse module and a related software application.

Abstract: A computer-based method is used for completing missing data needed in a transaction-tax-related application, where the method uses completing rules that define, depending on which missing data needs to be completed, what further data might be considered for deriving the missing data. A completing rule associated with the missing data is evaluated, and an auto-completion certainty parameter is determined as a result of the completing rule evaluation. Completed data is derived according to the certainty parameter.

Abstract: The invention is directed to a computer-based method for logging transaction-tax-related transactions, the method using rules which define, depending on transaction data, what transactions have to be logged, the method comprising: receiving a logging request for a transaction; evaluating the logging rules with transaction data of said transaction, logging said transaction if the result of the evaluation demands it. The invention is also directed to related software modules and a related software application.

Abstract: A method of making a data representation of transaction-tax-related information of a transaction in a database or a data file which can be processed by a computer. The transaction is represented by a transaction document having one or more transaction-document lines. The transaction-tax-related information associated with a transaction-document line has one or more taxation levels. The method includes arranging data items representing the transaction-tax-related information in the database or data file according to a data schema for representing transaction-tax information for different jurisdictions, including jurisdictions with different kinds and numbers of taxation levels. The data schema provides a taxation-line entity for each transaction-document line. It also provides a taxation-line-item entity, related to the taxation-line entity, for each taxation level of a transaction-document line.

Abstract: The invention is directed to a software interface for linking a business application to a component of a computer-based transaction tax processing system. The interface enables the exchange of commercial-transaction-related data, providing a mapping of the data between the business application and the component of the computer-based transaction tax processing system. The mapping is configurable via user-defined rules. The invention is also directed to a corresponding method and a corresponding computer program product.

Abstract: The invention is directed to a computer-based method for completing missing data needed in a transaction-tax-related application. I he method uses completing rules which define, depending on which missing data needs to be completed, what further data might be considered for deriving the missing data. The method comprises receiving a completing request; evaluating at least one completing rule associated with a missing data while using the further data defined as within this completing rule, returning the completed data if it could he derived from the further data. The invention is also directed to a related software module and a related computer program product.

Abstract: The invention is directed to a computer-based transaction tax processing system for providing, transaction tax services. The transaction tax processing system can be called by a calling application. The transaction tax processing system comprises at least one of the following basic service modules: a transaction tax calculation service, a transaction tax logging service, a transaction tax content service, a transaction tax compliance service, a transaction tax filing service, a transaction tax data base for storing selected information which is related to a transaction events. The transaction tax processing system further comprises: a first interface between the transaction tax system and the basic service module or modules and a second interface between the transaction tax system and the calling application. The first interface uses a Web protocol.

Abstract: A computer program product includes program code which provides, when executed on a computer system, an interface between a calling application and at least one callable application. The program code represents a computer program which implements at least two controllers which cooperate with each other and are at different hierarchical levels. The controllers are instances of a generic controller. The callable application may be a transaction-tax service application.
