I have a limited knowledge in OOPS programming.
i found that load_component_set is method in class cl_crm_bol_core.
i know that methods are calling in program through call method statement.
In below program we are calling method like lr_core->load_component_set( 'BP_APPL' ).
please explain the below code.
data: lr_core type ref to cl_crm_bol_core.
lr_core = cl_crm_bol_core=>get_instance( ).
lr_core->load_component_set( 'BP_APPL' ).
