Object Oriented BAPI access

[Harsh_Jain2512]

Hi,

Is object oriented access of BAPIs is possible  or through only FM we can access them in ABAP. If possible can somebody provide link to a documentation/example for that.

Regards,

What do you mean with "OO access?"

BAPIs are FM and as FM can be called both in "old way" FORM and in methods

Thanks Sabir for your response, but my question is that: Is the object Oriented access to BAPIs is possible in ABAP??? The link you provided is for OO BAPI access from other languages C++, Java. I want to know Is BAPI access in ABAP is possible only via FMs or classes are also there.

I think you are looking for some standard ABAP Object classes encapsulating business objects from the BOR (since BAPI's are the API's of business objects). I don't believe there are many (any?) provided by SAP.

However, you can create your own wrapper classes calling methods of business objects using dedicated FM's  starting with SWO_...

Here is a small example:

REPORT ybkpf_swo_test.

   PUBLIC SECTION.

Thanks Gabor for understanding yes I had to confirm are there any wrapper classes available for Business Objects, since I also googled a lot on this and I thinks  there are not any standard provided by SAP.
