Figure 1 BAPI eWay
The functionality of the SAP BAPI eWay simplifies the process of determining the
requisite IMPORT, EXPORT, CHANGING, and TABLE parameters—collecting all
the necessary data using the correct type and format, calling the Remote Function
Module (RFM) that represents the BAPI, and then extracting and parsing data from the
EXPORT and/or TABLE parameters.
1.2.1 Invoking BAPI/RFC Methods
Before it can be invoked, a BAPI or RFM requires the following parameters:
 IMPORT parameters: data provided to the BAPI
 EXPORT parameters: data returned by the BAPI
 CHANGING parameters: data provided to and/or returned by the BAPI/RFC
 TABLE parameters - data provided to and/or returned by the BAPI/RFC
The detailed metadata for these parameters such as descriptions of their value types
and mandatory or optional nature, can be found under SAP transaction SE37.
