- Tax Determination
- Tax Determination is a scalable and reliable J2EE-based tax calculation engine.
- JCo - Java Connector
- Java Connector, referred to as JCo, is a library created by SAP to allow connections between SAP and other solutions.
- Reading and writing data from JCo
- All RFC-enabled function modules use
getFieldandsetValuemethods of theJCo.Structureobject to exchange data between SAP and Tax Determination. - Support of different RFC types
- All RFC-enabled function modules handle Synchronous RFC (sRFC) as well as Transactional RFC (tRFC) and Queued RFC (qRFC). JCo supports all of the RFC types.
- Reporting errors to SAP
- All interfaces in the integration use either COM_ERR or COM_ERR_DOC APIs (structure) to report errors back to SAP.
- Logging
- All RFC-enabled function modules can log inbound and outbound data, as well as information about unsuccessful calls to Tax Determination through the connector. The function modules can log all transactions or specific documents by document number.
