Issue:

1)  I logged into Portal --> ESS --> Salary statement/Personal profile etc...

I am getting blank page as shown below  whereas it is working fine in backend/ECC system

2) I tested from sap admin, support giving details

note:  i had provided "WebDynpro Namespace" as sap

IT does NOT ask for "WebDynpro Configuration"

I got the same issue

3) Now, In the sap admin, support, test

I did NOT provide the WebDynpro Namespace & press the GO button

Now, It has asked me for WebDynpro Configuration details

Pressed GO button.. It is working fine this time. I could get WebDynpro application get loaded

Information:

The WebDynpro applications are working fine from backend ECC - se80

I had preview the preview the Iview from content admin -- I am facing the same above issue.

Kindly support..
