Hi All,

I want to know what all new object oriented concepts introduced into ECC 6.0 when compared to 4.6C version. Please provide the useful information.

Thank you

Hello Satya

I am not sure if there have been big changes regarding OO concepts. Basically all of them are already available in 4.6c.

Of course on ERP 6.0 you have many more classes and more powerful classes (in terms of methods) available.

Major differences that I am aware of are:

- RTTI (runtime type identification) " e.g. CL_ABAP_TYPEDESCR and other classes
- functional method calls " e.g. go_msglist = cf_reca_message_list=>create( ) was not possible on 4.6c
- public type definitions   " I think on 4.6c only protected and private ones were possible

Hi Uwe,

Thank you for ur information. But I have seen Friends tab page of se24 transaction (in addition) in ECC 6.0. From which my understanding is that Friends concept of object oriented programming has been introduced in ECC 6.0.

Thanks,

Satya

Hello Satya

You are probably right. For example, ABAP Unit Test Classes make use of the FRIENDS concept and they are available since >= 6.20.

However, the FRIENDS concept is something we do not have in Java (please correct me if I am wrong). My general approach to ABAP-OO is to program as Java-like as possible despite the differences between the two languages. Why?

You should always keep in mind that some day somebody else would / should / must take over your developments and we should make his or her task as easy as possible. Thus, always try to follow a generic and generally accepted way of programming.
