'How to' Workflow Macro Question

[Dart, Jocelyn]

Hi Raul, 
Firstly - I would always use Start Conditions (the new technique) in
preference to check function modules (the old technique).  If the
conditions are seriously complex I sometimes use a virtual attribute to
work out the hard part,e.g. "ApprovalReqd" yes or no, and then include
that in my start condition.  Just a thought for another possible
approach - but you know your scenario best. 

Secondly - to call an instance independent method, first create a dummy
object handle using the 
SWC_CREATE_OBJECT <object> <objecttype> <objectkey>
statement but putting initial values e.g. space in your object key. 
You can then call your instance independent method correctly.

Regards,
Jocelyn

Hi Raul, 
Good question, something I've not had to do yet. Let us know if you find
out.

However, a more elegant solution may be to use an attribute instead, and
evaluate that via start conditions. Either move the methods into attribs
or
create a new one that calls the methods - depends on your design. 

This also makes it possible to move any potential hardcoding out of your
ABAP
and into the condition; and the whole thing is easier to maintain and/or
add to
in future. 

Cheers
Mike
