User Roles & Authorization to run 'WebDynpro ABAP Application scenarios'

Question

Hi All,
I am developer and my user ID is having developer roles, so when i am testing
'WebDynpro ABAP Application scenarios' it is working fine.
Problem is when I am executing with enduser portal WWID's (i.e. WWID's are also defined as sap
user), 'WebDynpro ABAP Application scenarios' giving me dump in screen & in ST22.
Pls guide me what roles or authorization we need to assign to user ID's
who can use 'WebDynpro ABAP Application scenarios'.
URL for Webdynpro application is like : https://xxxx.yyyy.zzzz:/sap/bc/webdynpro/sap/ZPA_EXTENSION_U?ZDATA=10028705591320090406
ST22 Error when testing with portal WWID's
Runtime Errors         OBJECTS_OBJREF_NOT_ASSIGNED_NO
Exception              CX_SY_REF_IS_INITIAL
Short text
    Access via 'NULL' object reference not possible.
What happened?
    Error in the ABAP Application Program
    The current ABAP program "CL_WD_ADOBE_SERVICES==========CP" had to be
     terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
     caught in
    procedure "PARSE_XML_SCHEMA" "(METHOD)", nor was it propagated by a RAISING
     clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    You attempted to use a 'NULL' object reference (points to 'nothing')
    access a component.
    An object reference must point to an object (an instance of a class)
    before it can be used to access components.
    Either the reference was never set or it was set to 'NULL' using the
    CLEAR statement.
