BAPI/RFC mapplet parameters

BAPI/RFC functions use function parameter values to perform tasks. A BAPI/RFC mapplet includes input and output groups based on the BAPI/RFC transformation.

Function Parameters

BAPI/RFC functions can have the following parameters:

Function Parameter	Description
Scalar input parameters.	Scalar input values. Some BAPI functions require scalar input values to perform tasks such as changing data.
Scalar output parameters.	Scalar output values that a BAPI function returns after performing a task.
Table parameters.	SAP structures with more than one row. Table parameters can be input, output, or both. Input table parameters pass table input values to a BAPI/RFC function. For example, some BAPI/RFC functions require table inputs to change data.

Input and Output Groups

The BAPI/RFC transformation can contain the following groups:

Group Name	Description
Scalar input	Input group for scalar parameters. Contains a field for each scalar input parameter. The group name is SCALAR_INPUT and the field names are SI_<FieldName>.
Table input	One group for each table parameter. The fields represent import structures. The group name is TABLE_INPUT_<structure name> and field names are TI_<StructureName>_<FieldName>.
Scalar output	Output group for scalar parameters. Contains a field for each scalar output parameter. The group name is SCALAR_OUTPUT and field names are SO_<FieldName>.
Table output	One group for each table parameter. The fields represent output structures. The group name is TABLE_OUTPUT_<structure name> and field names are TO_<StructureName>_<FieldName>.
Error output	Passes data from data conversion errors and invalid BAPI/RFC calls. Map the error output field to a target to see error messages about data conversion and BAPI/RFC calls.
