Executing a Function 

Activities

The following section describes how a function is executed by calling a function module.

 

Example: You want to call the BAPI CompanyCode.GetList. The corresponding RFM is called BAPI_COMPANYCODE_GETLIST. This RFM does not contain any import parameters.

...

       1.      Create a JCO.Function object and call the method execute() of the JCO.Client object by entering the JCO.Function object as a parameter. The BAPI has two export parameters.

       2.      All parameters of a JCO.Function object can be called using the methods getImportParameterList(), getExportParameterList(), and getTableParameterList().

       3.      The method getStructure() facilitates access to any structure parameter in an import or export parameter list.

 

Executing a Function

JCO.Function function = null; function = this.createFunction (“BAPI_COMPANYCODE_GETLIST“); mConnection.execute(function);   JCO.Structure returnStructure =    function.getExportParameterList ().getStructure (“RETURN“); if (!  (returnStructure.getString(“TYPE“).equals(““)  ||          returnStructure.getString(“TYPE“).equals(“S“))  )   {    System.out.println(returnStructure.getString (“MESSAGE“));    System.exit (1); }
