There was a recent discussion on twitter about how to get to know BOPF better.

As all the mentions ( Gregor Wolf, Volker Wegert , Fred Verheul, Martin Fischer, Custodio de Oliveira, James Wood ) made it impossible to actually add content in a new tweet, this “blog” shall serve as container for longer messages. Let’s see whether this works out.

There is a course WDEBOF at SAP university which is an onsite-training. I’m a trainer for that course.

Let me give you some insights on the course:

  • Duration: The course is designed for two days. I never managed to get all the content even read in two days. For a serious knowledge-transfer, at least a third day is necessary. The inhouse-training at SAP took five days for the same content. When I held the course, I cut some advanced chapters in favor for excercises.
  • Content: ABAP is essential pre-requisite, but some architectural knowledge helps a lot. I even had the experience that an ABAP Newbie who was a good C# developer and architect showed the best understanding.
  • Location: The course is a class-room-training and I like it that it is. There’s usually a lot of interaction during the exercises (“why do I get this shortdump?”) and questions during the slides (“can this be compared to…?”). Having it in a VC would definitely require a different set-up (you can’t have persons 8hrs/day online listening). On the other hand, a code-jam is much too short if you want to productively use it afterwards.
  • Requesting a training: Apart from the planned dates which you can get from the course’s page, individual trainings also at other sites are common (to train a team of developers about to implementing something e. g. in TM).
    Therefore, I guess that it should be possible to request an offer by SAP for a custom training, even a VC – if there were enough participants joining.

Are you interested in participating? Leave a comment and we’ll see to the feedback.

Cheers,

Oliver

    It’s likely that the dubious hohor of having started the avalance will be attributed to me, so…

    I don’t really need BOPF right now for anything related to my current occupation or work-related projects – unless there’s been something going on that hasn’t reached me yet, BOPF is not in use within IS-H and i.s.h.med.

    However, I’m currently working on a rather large side-project in my own time that I use as a test bed to try out lots of cool new (well, more or less new) stuff that I haven’t had the opportunity to check out yet. BOPF is one of the things I’d like to get familiar with since it sounds interesting. As this is a private project, I’m not in a position to request a WDEBOF training, especially since training my co-workers in this framework would probably be of little use for them. I might be able to take some time off for a class-room training, but for me, a VC (or even paid-for access to high-quality training materials) would probably be the best option.

      Whenever you create a Z-Table containing application data (type A) you need to think about how to integrate it transactionally. Thus, BOPF might make good sense although you don’t know yet that you need it 😉

      Maybe I (or someone else) should write a book 😉

        Well, one could always use persistent classes… *ducks and runs*

        But aside from that, a big issue is how the cool new persistence and object management framework is coupled with the existing application. I’m curious how BOPF achieves that. In i.s.h.med, when we need A tables, chances are that we’re talking about medical documentation, and we’ve got our own “application generator” named PMD (not related with the famous source code checker) for that.

        I’m inclined to reply both “yes” and “no”. As a prospective customer – yes, please do, I would already have bought it if it was available. However, writing an entire book is an awful lot of work. BTDT – I’ve written a set of books about said “application generator” myself (and for lack of interest without the “help” of a publishing company). It was a fun and interesting experience, but I know why I didn’t do a time sheet for this particular project – that would have turned out really depressing…

    Hi Oliver,

    I would be very interested in a training session. Is this something that is still offered? I’m sure I could get a few other participants from my company as well.

    Thanks!

    Hi Oliver,

    As going forward BOPF is very essential for any new development please do notify me when it is possible waiting to get hand’s on BOPF framework

    Thanks

    Hi Oliver,

    since we met on TechEd some years ago where you described me your BANF creation frontend …

    • BOBF is avialible for public(used by SCE TM and others)
    • it provides great opportunities for OData generation out of SEGW with help of SADL

    Now the time has come where it’s definitely worth to unterstand and use it.

    E.g we use transient nodes to map external APIs to BOB artefacts (we are “BOBy-fying” APIs).

    Before BOBF, we are “OData-fying” our APIs but it does not feel natural to do this in SEGW DPC_EXT methods. So we stared thinking about designing and writing own “persistency” stuff.

    But all SEGW CRUD operations lead to centralized own written CRUD framework looking like …

        SELECT SINGLE (lt_columns) FROM (lv_from)
          INTO CORRESPONDING FIELDS OF @er_entity
         WHERE (lv_where).
        /viastore/cl_mycps_7=>iwbep_handle_select_subrc(
            iv_subrc   = sy-subrc
            it_columns = lt_columns
            iv_from    = lv_from
            iv_where   = lv_where ).
    

    … which cannot be the future 😉 Even sometimes a …

       26     "if we reach this point, we are NOT called from a unit test
    >>>>>     MESSAGE me TYPE 'X'.

    …. will be fustrating.

    So it would 100% good to have a expert like you talking BOPF in a session. Is 3 to run from SAP education a way to request it ?

    Thanks & best regards,
    Matthias
