SAP Connector v4.2

Class that has an overall configuration for the SAP extension.

Release Notes: SAP Connector Release Notes

Configurations

Inbound Configuration

Default configuration for SAP extension inbound elements.

Parameters

Name Type Description Default Value Required

Name

String

The name for this configuration. Connectors reference the configuration with this name.

x

Connection

Simple Connection Provider

The connection types to provide to this configuration.

x

Expiration Policy

Expiration Policy

Configures the minimum amount of time that a dynamic configuration instance can remain idle before the runtime considers it eligible for expiration. This does not mean that the platform expires the instance at the exact moment that it becomes eligible. The runtime purges the instances when it sees fit.

Encoding

String

Canonical name of an encoding. See Oracle’s Supported Encodings.

Inbound Connection Types

Simple Connection Provider

Connection provider that connects using username and password.

Parameters
Name Type Description Default Value Required

String

The two-digit system number (sysnr) of the SAP system.

x

SAP client ID

String

Three-digit client number. Preserve leading zeros if they appear in the number.

x

Destination Name

String

Identifier of the destination generated by this connector. If none is set, then a random value is created.

Login language

String

false

Enable CPIC tracing on server

Enumeration, one of:

Execute BAPI Function over qRFC

<sap:execute-queued-remote-function-call>

Executes a BAPI function over a queued remote function call (qRFC). A queued RFC is an extension of tRFC that ensures that individual steps are processed in sequence.

To guarantee that multiple LUWs (Logical Unit of Work transaction) are processed in the order specified by the application. tRFC can be serialized using queues (inbound and outbound queues). Hence the name queued RFC (qRFC).

Use qRFC to extend the Transactional RFC Defined processing sequence.

Implementation of qRFC is recommended to guarantee that several transactions are processed in a predefined order.

Execute BAPI Function over sRFC

<sap:execute-synchronous-remote-function-call>

Executes a BAPI function over a Synchronous Remote Function Call (sRFC).

A synchronous RFC requires both the systems (client and server) to be available at the time of communication or data transfer. It is the most common type and is required when result is required immediately after the execution of sRFC.

sRFC is a means of communication between systems where acknowledgments are required. The resources of the source system wait at the target system and ensure that they deliver the message and data with ACKD. The data is consistent and reliable for communication.

If the target system is not available, the source system resources wait until the target system is available. This may lead to the processes of the source system to go into Sleep RFC or CPIC Mode at the target systems and block these resources.

sRFC is best used for:

  • Communication between systems.

  • Communication between SAP Web Application Server to SAP GUI.

Parameters

Name Type Description Default Value Required

String

The name of the configuration to use.

Execute BAPI Function over tRFC

<sap:execute-transactional-remote-function-call>

Executes a BAPI function over a Transactional Remote Function Call (tRFC).

A tRFC is a special form of asynchronous Remote Function Call (aRFC). Transactional RFC ensures transaction-like handling of processing steps that were originally autonomous. tRFC is an asynchronous communication method that executes the called function module in the RFC server only once, even if the data is sent multiple times due to some network issue. The remote system need not be available at the time when the RFC client program is executing a tRFC.

The tRFC component stores in the called RFC function together with the corresponding data in the SAP database under a unique transaction ID (TID). tRFC is similar to aRFC as it does not wait at the target system (similar to a registered post). If the system is not available, this operation writes the data into aRFC tables with a transaction ID (SM58), which is picked by the scheduler RSARFCSE that runs for every 60 seconds.

tRFC is best used to extend asynchronous RFC for secure communication between systems.

Send IDoc

<sap:send>

Sends an IDocument to SAP over an RFC.

An RFC can be one of two types for IDocuments:

  • Transactional (tRFC) - A tRFC is a special form of asynchronous Remote Function Call (aRFC). Transactional RFC ensures transaction-like handling of processing steps that were originally autonomous. tRFC is an asynchronous communication method that executes the called function module in the RFC server only once, even if the data is sent multiple times due to some network issue.

    The remote system need not be available at the time when the RFC client program is executing a tRFC. The tRFC component stores the called RFC function, together with the corresponding data, in the SAP database under a unique transaction ID (TID). tRFC is similar to an aRFC as it does not wait at the target system (Similar to a registered post).

    If the system is not available, it writes the Data into aRFC Tables with a transaction ID (SM58) which is picked by the scheduler RSARFCSE (runs every 60 seconds). Use tRFC to extend an asynchronous RFC for secure communication between systems.

  • Queued (qRFC) - A queued RFC is an extension of tRFC that ensures that individual steps are processed in sequence. Use to guarantee that multiple LUWs (logical unit of work transactions) are processed in the order specified by the application. A tRFC can be serialized using queues (inbound and queues). Hence the name queued RFC (qRFC). Use qRFC to extend the transactional RFC defined processing sequence. Implement qRFC to guarantee that several transactions are processed in a predefined order.
