Connectivity

Connectivity problems may occur when defining or connecting to a SAP ERP target using iWay Explorer. Check with your system administrator and verify that all SAP ERP server and logon information is correct. For more information on how to create and connect to a target, see Configuring Adapter Targets and Creating XML Schemas.

RFC / BAPI

Remote Function Call (RFC) is the standard SAP ERP interface for communication between SAP ERP systems. The RFC subsystem calls a remote enabled function to be executed in a target system.

BAPIs (Business Application Programming Interfaces) play an important role in the technical integration and in the exchange of business data between SAP ERP components, and between SAP ERP and non-SAP ERP components. BAPIs have a release and versioning system, and you must be sure that the BAPI you are attempting to use is in a valid release state before proceeding.

For customer created Remote Functions or BAPIs, verify that the functions are in correct release state and that standard ABAP programming conventions have been followed. If you experience a problem with a custom RFC/BAPI/IDoc, you must be prepared to send the source code for examination and duplication of the problem.

IDoc

In SAP ERP systems, the IDoc interface is used to exchange business data between two different Systems in an asynchronous manner.

The IDoc interface consists of the definition of a data structure and the processing logic for this data structure. The systems involved must both recognize the data format used to exchange the data, this is done through segments and versioning.

The IDoc must be in a released state for the SAP ERP version you are using, and all segments must be released for the IDoc and release. The IDoc type must be assigned to a valid Message Type. At run time, determine whether you are integrating with collected IDocs or single IDocs, and adjust the SAP ALE profile parameters accordingly.
