Roles

I am invoking an RFC from within my Web DynPro application.

The RFC - BINARY_REL_DELETE is used to remove a

link between a business object and an attachment.

Specifically, I am using the function to delete a relationship

for a Purchase Requisition -- BUS2105. When I invoke the

function it throws a NO_ROLE exception. But if I log on

to my ABAP workbench and invoke the function using the

same parameters, the function executes successfully.

I also created a Web DynPro iView and launched the application

from within the portal, but the same exception was thrown.
