Calling multiple BAPIs within a single connection

To use some BAPIs, it is necessary to call more than one BAPI within the same connection or transaction. To do this, use Java code such as the example shown below. You would access this code using the Linked Java Object builder, in which you would use the callSAPFunction method from an Action List or Method in the builder.

This code makes use of two supporting classes that are provided with the SAP builders:

  • SAPAccess is the class that manages connections to SAP via JCO.

  • SAPCall is used to invoke a single BAPI. You can create an SAPCall object by calling createSAPCall from the SAPAccess object. From there you can programmatically set Imports on this object, execute the BAPI, and get results from Exports or Tables.

Note: To compile this code in your IDE, you will need to add the WEB-INF/work/lib/SAP_Builder.jar to your compile classpath.
