SAP BAPI Adapter Connectivity Map Properties

When you connect an External Application to a Collaboration, Java CAPS IDE automatically assigns the appropriate Adapter to the link. Each Adapter is supplied with a template containing default configuration properties that are accessible on the Connectivity Map. The following figure illustrates the SAP BAPI properties.

Figure 1 Outbound Adapter Properties

Inbound SAP BAPI Adapter Properties

The Inbound Adapter Properties include parameters required to receive data from SAP R/3 into Java CAPS. The following server connection settings are configured in the Inbound Adapter Properties window.

Server Connection Settings

The following Server Connection Settings are used by the external database:

Table 5 Inbound Adapter—Server Connection Settings

Name	Description	Required Value
Enable RFC Trace	You enable RFC tracing with the `Enable RFC Trace` property. The trace file contains RFC API calls, and data sent to and received from the SAP R/3 host. The trace file is `rfcnumber.trc`, for example, `rfc00310_0156.trc`.	Yes or No. The default mode is No; the RFC tracing is disabled. Setting the Enable RFC Trace parameter to Yes creates both the JCo and RFC Trace logs. Both are created in the same location under: appserver\domains\domain1\ config The JCoTrace log provides Java Runtime, version, and path information. It also provides a manifest. If Enable RFC Trace is set to No, then no trace file is generated.
RFC Trace Level	Trace level specifies the complexity of the information in the trace file. 0 provides minimal trace logging and 5 provides the maximum trace logging of diagnostic information in the trace file.	An integer value from 0 to 5. The default number is 0. The Enable RFC Trace level only affects the JCo trace level. It has no effect on the RFC trace level.
Number of RFC Servers to create	Specify the number of RFC servers to create. The created RFC servers facilitate parallel processing when receiving multiple requests from SAP R/3.	A valid integer value. The default number is 1.
Transaction Mode	Specifies the transaction mode. The transaction mode specifies whether tRFC is enforced. With tRFC, transactions have unique TIDs and are processed only once by this Adapter.	A transaction mode of Non-Transactional or Transactional RFC(tRFC) The default mode is Non-Transactional.
Transaction ID Verification Database	Specifies the location of the Transaction ID Verification database. Specify the name of the file-based database which persists the TIDs. Provide the path to the database file that records the disposition of all transactions outgoing from this Adapter. The database records whether transactions are: C (committed) U (unprocessed or rolled-back) R (reserved or pending)	A valid path to the database file. For example, the default location is: `C:\JavaCAPS6\data\SapTRFC. TIDdb`

Outbound SAP BAPI Adapter Properties

The Outbound Adapter Properties include parameters required to communicate from Java CAPS to SAP/R3. The following server connection settings are configured in the Outbound Adapter Properties window.

Client Connection Settings

The following Client Connection Settings are used by the outbound adapter:

Table 6 Outbound Adapter—Client Connection Settings

Name	Description	Required Value
Client Connection Mode	Determines the type of client connection to use when logging onto SAP R/3.	Automatic or Manual. The default mode is Automatic.
Enable RFC Trace	You enable RFC tracing with the Enable RFC Trace property. The trace file is `rfcnumber.trc`, for example, `rfc00310_0156.trc`.	Yes or No. The default mode is No; the RFC tracing is disabled. Setting the Enable RFC Trace parameter to Yes creates both the JCo and RFC Trace logs. Both are created in the same location under: appserver\domains\domain1\ config The JCoTrace log provides Java Runtime, version, and path information. It also provides a manifest. If Enable RFC Trace is set to No, then no trace file is generated.
RFC Trace Level	Trace level specifies the complexity of the information in the trace file. 0 provides minimal trace logging and 5 provides the maximum trace logging of diagnostic information in the trace file.	Integer value from 0 to 5. The default number is 0. The Enable RFC Trace level only affects the JCo trace level. It has no effect on the RFC trace level.
Transaction Mode	Specifies the transaction mode. Non-Transactional: Actions performed by BAPI call are committed immediately and automatically by SAP R/3 (auto commit). In this mode, use the `execute()` method in the OTD. Transactional RFC (tRFC): Adapter communicates with SAP R/3 using unique transaction IDs (TID) to avoid message repeats. Use the executeAsynchronous(eid) method in the OTD in this mode. VIA COMMIT/ROLLBACK BAPI: Performs a single phase commit, where actions performed by BAPI calls are committed or rolled back by calling BAPI_TRANSACTION_COMMIT or BAPI_TRANSACTION_ROLLBACK. In this mode you must use the commit and rollback methods on the BAPI/RFC OTD.	A transaction mode of Non-Transactional or Transactional RFC(tRFC), or VIA COMMIT/ROLLBACK BAPI. The default mode is NON-TRANSACTIONAL.
Transaction ID Verification Database	Specifies the location of the Transaction ID Verification database. Specify the name of the file-based database which persists the TIDs. Provide the path to the database file that records the disposition of all transactions outgoing from this Adapter. The database records whether transactions are: C (committed) U (unprocessed or rolled-back) R (reserved or pending)	A valid path to the database file. For example, the default location could be: `C:\JavaCAPS6\data\SapTRFC. TIDdb`
Maximum TID Database Rows	Specifies the maximum amount of rows for the Transaction ID (TID) database for outbound adapters. Set this property only if tRFC is used. This property specifies the maximum number of rows in the outbound TID database that are kept before the oldest rows are purged and their corresponding TIDs confirmed on SAP R/3. Confirmation allows SAP R/3 to remove those TIDs from its TID tracking database and reduce resource consumption.	At least 1 row. The default is 200 rows.
Enable ABAP Debug Window	Enables the ABAP debugging window. Enabling the `Enable ABAP Debug Window` property opens the ABAP debugging window on the Application Server. The window shows the debug information for the RFC-enabled ABAP application that is called by SAP R/3. This property only works if the SAPGUI software is installed on the Application Server.	Yes or No. The default mode is No; the ABAP Debug window is disabled.
Use Load Balancing	Enables load balancing for outbound adapters. This property allows you to take advantage of the workload balancing provided by SAP R/3. SAP R/3 provides workload balancing to automatically route requests to the SAP application server within a group of servers that has the best response time determined at that moment by an SAP message server. If you disable load balancing, use the `System number` property.	Yes or No. The default mode is No; load balancing is disabled by default.
