The connector uses the value of an attribute's application-specific information to determine which importing, exporting, and table parameters to use. The value of this property contains the prefix I (for importing parameters) or E (for importing parameters). The prefix indicates whether the attribute value is used to pass data into or out from the SAP application.
Because structure parameters can be either importing or exporting, they use either an I or an E before the parameter value. Because table parameters can pass data to and return data from a RFC-enabled function, they can have both I and E parameter values.
Figure 30 illustrates the mapping between a business object and an example RFC-enabled function named BAPI_EXAMPLE. In the example, the simple attributes (Attribute_1, Attribute_2, and Attribute_3) specify only an importing or exporting parameter. The attribute that represents a child business object (Child_1) maps to an exporting structure parameter. The attribute that represents an array of child business objects (Child_2) maps to a table parameter.
Each child business object has a simple attribute that maps to a field of the corresponding structure or table (Attribute_11 and Attribute_14, respectively). You can find these fields by looking at the details of the BAPI.

Table 42 identifies the format of the application-specific information for specific kinds of attributes.
Table 42. AppSpecificInfo format for specific kinds of attributes
AppSpecificInfo Format | Attribute Type |
---|---|
IParameterName:EParameterName | Simple |
ITableName:ETableName | Represents a child business object mapped to a table parameter |
IStructureName:EStructureName | Represents a child business object mapped to a structure parameter |
IFieldName:EFieldName | Represents an attribute of a child business object mapped to a field in a table or structure parameter |
SAPODA automatically generates the appropriate application-specific information for your business object definition. It is recommended that you do not change the parameter names of the generated application-specific information.
