/***Start of JRA specific code***//
// Retrive connection factory                
InitialContext initialcontext = new InitialContext();
connectionfactory = (ConnectionFactory) initialcontext.lookup("java:comp/env/ConnFactory");
//Request a connection handle:
connection = connectionfactory.getConnection();
//Create a RecordFactory object to get a metadata description
// of the RFC SALERT_CREATE
RecordFactory recordFactory = connectionfactory.getRecordFactory();
// Create Record objects containing all
// necessary information about the RFM.
MappedRecord input = recordFactory.createMappedRecord("SALERT_CREATE");
//Fill in the import parameters and the import table structure data here
input.put("IP_CAT", "ALRT_CAT"); // alert category
// Refer to the SW_CONT structure of the table of RFC SALERT_CREATE
ResultSet inputITContainer = (ResultSet) input.get("IT_CONTAINER");
int tabIndex = 0;
inputITContainer.moveToInsertRow();
inputITContainer.updateString("ELEMENT", "CONT_1");
inputITContainer.updateString("TAB_INDEX", "" + tabIndex++);
inputITContainer.updateString("ELEMLENGTH", "250");
inputITContainer.updateString("TYPE", "C");
inputITContainer.updateString("VALUE","Container_1 value");
inputITContainer.insertRow();
inputITContainer.moveToInsertRow();
inputITContainer.updateString("ELEMENT", "CONT_N");
inputITContainer.updateString("TAB_INDEX", "" + tabIndex++);
inputITContainer.updateString("ELEMLENGTH", "250");
inputITContainer.updateString("TYPE", "C");
inputITContainer.updateString("VALUE","Container_N value");
inputITContainer.insertRow();
interaction = connection.createInteraction();
// execute the call with the input parameters.
interaction.execute(null, input);
}catch(Exception e){
     // Error handling code goes here
}finally{
     try {
                if (interaction != null)
               interaction.close();
          if (connection != null)
               connection.close();
     } catch (Exception ignored) {
          // Do nothing
// Pass on module data to the next module in chain, unaltered
return moduleData;
