OBN Error- There is no iView available for system "SAP_ECC_DefenseAndPublicSecurity": object "mat_doc_disp".
I come across OBN error when I launch URL link for SAP Transactional iView.
"There is no iView available for system "SAP_ECC_DefenseAndPublicSecurity": object "mat_doc_disp". For more information, contact your administrator."
Please find the attached Business Object "mat_doc_disp" properties.
Looks like its configured under system name "SAP_ERP_Manufacturing".
I add both these system in Aliases, still this not solving the issue.
I am also referring to SAP Note 1494536. Still couldn't pin it down the issue.
As you've already gone through the central SAP Note for OBN (1494536), please refer to the below blog for Troubleshooting Object Based Navigation Error :
Hope this helps!!!
