Is there a security issue when assiging iReceivable responsibilities to GUEST users

Dear Oracle iReceivable Guru,

We are in a process of implementing iReceivable application and came to know we need to assign several iReceivable responsibilities such as iReceivables Self Service & iReceivables Registration to

Oracle GUEST user. We would like to know the following:

  1- Are there any different implementation approach than assigning noted responsibilities to GUEST user?

  2- Is there a security risk when using GUEST as your external users?

      Note: I know we are implementing through Oracle DMZ defined environment.

Thanks for your feedback and assistance on this question.
