Hi
I think SAP likes to make it easy for us.
SWTYPV is triggering SM30 on view SWFDVEVTY2
SWEINST is triggering an SM34 on report RSWEINSTVMAINT
SWE2 is triggering an SM30 on view SWFDVEVTY2
From a workflow functionality point of view I don't think that there are much differences ...
The design is a little different with SWEINST with the little tree on the left hand side and the entry is not done in the same way but no other difference.
Cheers
Stephane
