copied!<p>You should put your class A and B definitions and implementations inside separate includes, and include those along with the interface inside the report containing your main class. Like this: </p> <pre><code>report zzz_impl. include zzz_incl_interface. include zzz_incl_a. include zzz_incl_b. class lcl_main definition final create private. public section. class-methods: main. endclass. class lcl_main implementation. method main. data l_rif_test type ref to lif_test. create object l_rif_test type lcl_test_b. create object l_rif_test type lcl_test_a. endmethod. endclass. end-of-selection. lcl_main=>main( ). </code></pre> <p>The reason for the shortdump, is because you're trying to use a variable of the type \PROGRAM=ZZZ_IMPL_<strong>B</strong>\INTERFACE=LIF_TEST to refer to an object which implements \PROGRAM=ZZZ_IMPL_<strong>A</strong>\INTERFACE=LIF_TEST.</p> <hr> <p>Edit: I'm not entirely sure what you mean with your comment, but maybe generating the entire report is possible for your use case? For example: </p> <pre><code>report zzz_impl_gen. data source_interface type standard table of char255. append `interface lif_test.` to source_interface. append ` methods:` to source_interface. append ` test.` to source_interface. append `endinterface.` to source_interface. data source_class_a type standard table of char255. append `class lcl_test_a definition final.` to source_class_a. append ` public section.` to source_class_a. append ` interfaces:` to source_class_a. append ` lif_test.` to source_class_a. append `endclass.` to source_class_a. append `class lcl_test_a implementation.` to source_class_a. append ` method lif_test~test.` to source_class_a. append ` endmethod.` to source_class_a. append `endclass.` to source_class_a. data source_class_b type standard table of char255. append `class lcl_test_b definition final.` to source_class_b. append ` public section.` to source_class_b. append ` interfaces:` to source_class_b. append ` lif_test.` to source_class_b. append `endclass.` to source_class_b. append `class lcl_test_b implementation.` to source_class_b. append ` method lif_test~test.` to source_class_b. append ` endmethod.` to source_class_b. append `endclass.` to source_class_b. data source_main type standard table of char255. append `class lcl_main definition final create private.` to source_main. append ` public section.` to source_main. append ` class-methods:` to source_main. append ` main.` to source_main. append `endclass.` to source_main. append `class lcl_main implementation.` to source_main. append ` method main.` to source_main. append ` data l_rif_test type ref to lif_test.` to source_main. append ` create object l_rif_test type lcl_test_b.` to source_main. append ` create object l_rif_test type lcl_test_a.` to source_main. append ` write: / 'Hello, World!'.` to source_main.
