LPOR restriction v tightly-coupled SAP systems

[Griffiths, Mark]

Hi Mike,

Hope all is well in snowy Staines!

In my experience if you need a workflow which crosses systems the more normal approach is to trigger events in the other system and wait for a response, or maybe even consider WF-XML.  Having said that, that could just because no one else has considered trying to use objects from one system natively in another, which I must say is a very nice idea!

Generally CRM and ECC workflows don't often interact, this is because very few CRM implementations use much workflow as the CRM gods have never supported the execution of workflow work items from the CRM Agent inbox in a very satisfactory manner.  Instead most CRM workflow-like processes use CRM 'Activities' which do a fairly similar job to tasks from a process point of view.  In CRM to expose functionality from say an ECC system you will probably first consider the CRM BOL (Business Object Layer, but not as we workflowers know it) to do the integration - I'd advise you speak to your friendly neighbourhood CRM specialist programmer as by all accounts it is a totally different paradigm in ABAP programming.

Regards,


Mark

Subject: [LIKELY JUNK]LPOR restriction v tightly-coupled SAP systems

Hello WUGgers,

When we upgraded to ECC 6 early last year I bemoaned the apparent demise of the Logical System field since the Workflow Gods had deemed it to be obsolete. Instead they commanded a system-wide switch to the Local Persistence way of doing things (LPOR).

Despite my concern at the time, back then we didn't really have much of need to use LOGSYS because:

  a) we don't use multe-clients (we still don't)

and

  b) we only really had 1 SAP box to worry about.

So I was only puzzled on a theoretical level.

That picture has changed though because our landscape has evolved. We now have a PI box and an ERP box playing with each other. Very soon the latter will be tightly coupled to a new CRM box too. And all three will have Workflow running on them in various forms for various reasons.

And there's the rub...if I wanted to model a Workflow in CRM that could natively make use of object instances that actually pointing to the ERP system this doesn't appear to be something that conforms to the new WF rules. I can already imagine a whole host of Business Processes that might want to straddle the middle-ground and work with instances on boths sides...

Of course the LOGSYS field is still there (for now) and I suppose I could make use of it anyway and build msyelf nice RFC-based Object wrappers and shoe-horn remote instances into our Workflows. But, I can't help but think that SAP have really missed a trick here, particularly with clients who have been suckered/persuaded* into buying a CRM-ERP platform (*delete where applicable).

Is anyone else here flummoxed by this decision or am I the only one howling at this particular moon?
