ABAP Objects - Percent of WF'ers using ABAP OO?

Thu Feb 24 08:19:45 EST 2011

It may seem overwhelming at first, but not too bad. Before I even touched SE24, I did a lot of reading. Something to do when in meetings <G>. Use SDN, Google, etc. for PDFs. Lots of good stuff. And then there is the SAP training.

By NO MEANS am I advanced in ABAP OO. Just scratching the surface. Just like when I look at my first projects in ABAP, I am sure I will gag and vehemently deny I wrote it the piece of junk.

Get your feet wet. Buy the book, "Practical Workflow for SAP 2nd Edition". I have the first one, 2nd is on order. (Cha-ching!)

Read Jocelyn's blog on SDN. REALLY good start. Instead of ZCL_PLANT, I just used Sales Order as key, in Display method just CALL VA03, etc. etc. Replaced with my requirements. And then you have a solid start.

If the "high domes" (that's a compliment folks) aren't around to answer, you can count on me to give my opinion.

We thank you for sharing.. and will surely read back when I’ll try it.. but currently I’m flabbergasted ☺ and I feel totally old fashioned and not capable.
So I’ll go buy prozac first ☺

Keep up the good work.

Whoa! I never stated anything about passing a BOR objects 'into' an ABAP OO objects or vs versa. Sorry if I did not communicate that well. Maybe it is just early and I misread what Rina was saying.

I 'thought' she was referring to binding the WF-BOR (with its display method) to a Task. And then binding another ABAP OO (with its display method) to the same Task. Then, you would have to two links on the Task in the Description pane with two different Display method links.
Like, in the default Display BOR method, open VA03. One Display method from the BOR and the other Display from the ABAP OO.

I use one or the other in a task for this WF so I don't have that issue.

I have used multiple BOR object in past for HR work, like the W-4 object, employee object, etc. All providing its own Display link and method call and find that handy so the intended user can review the data.

p.s. for others:
I apologize if I come across as a little 'off' or long winded. Just me trying to dig for answers and give credit where credit is due. And I always keep myself open and available in forum or sent directly to me. I just pass along any of my findings and hope it sheds light on a subject that someone may be able to use.

Rick,

The concept of 'passing' anything between BOR and ABAP OO is probably going to cause you a monumental headache.

Containers based on the SWCONT structure are just too far behind their newer ABAP_PARMBIND equivalents to understand the concept of an ABAP OO instance.

'TYPE REF TO data' simply did not exist back then. Just as 'TYPE BOXED' is going revolutionise the Data Dictionary (at long last!) and hasn't quite hit us yet in the current world.

But you may have hit that iceberg already...

Hi Rina,

You will only get the display method link if you pass in an objects. Any object you pass into a task with a display method will create the link. I only have my ABAP object used in task tsxxxx, so I only see one.

Did I miss read this, or this what you referring to?

Dear Rick ,
Good  for you if you are  happy  with your craft .

Hopefully  you  had at least 2  display methods to implement  so no  one asks why  there   are  2   links that  point to the same  VA03.
I  also  do this mixture  not so sure any one except me will find  where to  look  what ,
Best Regards

All interested parties,

Like I said, I am at the beginning of completing my first prod app in ABAP OO. Low priority thing to test the waters for our company and  expand our knowledge. So I was poking a lot of people to get an idea of the best place to start.
Thanks ALL for input. Especially Mike, Mike, and Jocelyn.

Yes, I am still waiting for my book "Practical Workflow for SAP 2nd Edition". (Can't wait for my royalty checks for plugging the book!)

At this point, I just kept my design as simple and light weight as possible. I will expand on my (small) frame work / interfaces for all my known common functions (best I can anyway) and refactor / evolve  when and where needed. It is a low priority project, not the never ending story, so I had to take my best shot and go with what I know.

Didn't touch the exits, type linkages, etc. to create events in ABAP OO, I just caught the standard BOR BUS2032.CREATE / CHANGE and instantiate the object when the flow starts. I already had that in place, so I know this works. Good enough for now. I will need GOS so I can't get away from using BOR anyway.

I have kicked off a Sales Order WF by using BOR events, using an ABAP OO class as the core business code warehouse for this project. Simple functionality at this point, but it fills the requirements.

So Gavin, add (1) to that list not employed by SAP to use ABAP OO.

Bottom line, did I 'need' ABAP OO for anything I did. Absolutely not. Just to get me feet wet type experience and see what I can leverage from OO. It was actually kinda fun. A lot of digging in the SWT* packages for some simple how to code like get/set container, raise event, etc. Basic WF functionality but in OO.

Reference Jocelyn Dart "Why use ABAP OO with Workflow".
Thanks Jocelyn. Excellent tutorial to make 'something' actually work.
