Linking of SRM OBN with Custom SRM POWL WDA application

Hi All,

We have our Producer portal with version 7.0 sp14 and Consumer with version 7.4 sp05.

We have "Check Status" a SRM Standard POWL application integrated in portal and all the Navigation OBNs are working fine with it.

our ABAP team developed a custom POWL application only for Buyers to show the shopping carts.

We have successfully integrated the POWL application in SRM portal.

we have added the iView to Role and added the navigation folder with all BO objects for OBN.

however when we assign the role to user, we are getting Portal Runtime Error.

Please help us on how to link OBN Business Objects with Custom POWL application.

Thanks in advance.

Regards,

Vijay.
