10pt; COLOR: navy; FONT-FAMILY: Arial">Thank you for your response. When I added the IF_WORKLFOW
interface it also added the BI_PERSISTENT and BI_OBJECT interfaces. It did that
because the IF_WORKFLOW interface inherits from those BI_PERSISTENT which in
turn inherits from BI_OBJECT.</span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style="FONT-SIZE:
10pt; COLOR: navy; FONT-FAMILY: Arial">The
reason that I chose BI_PERSISTENT was because the interface defines the LPOR
method. I want to call this method so I can get the ObjectType and Key of
<STRONG>any</STRONG> instance that is passed into my Workflow. However, it seems
that the current implementation of the Workflow builder does not allow this. I
have to specify a concrete type and not an interface as the type
definition of my container element. </span></font></p>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Your suggestion of not
specifying a class (type) worked but still did not give what I want. Ultimately
I want to take this instance and cast it to a reference of BI_PERSISTENT. It is
'this' that I can not do and therefore greatly reduces my ability to deal with
'abstraction' in my design. </SPAN></FONT></P>

It seems that I can not declare a container element of type <em><i><font
face=Arial><span style="FONT-FAMILY: Arial">interface</span></font></i></em>.
The workflow editor requires a concrete type and will not allow me to specify
an element whose type is an interface. The way I see it, this basically blows
away any polymorphic behaviour within Workflow and greatly reduces the benefits
of using OO in SAP Workflow (feel free to let me know that I am over reacting).
To make things worse I can achieve this using the old BOR by simply not
specifying a type.</span></font></p>
