Sharepoint web page part : error #401
I'm trying to capture a Sharepoint web part page into SAP portal.
I have defined a URL iview with expected Sharepoint web page.
When I test the preview function, Sharepoint web page is correctly displayed.
But, when I try to capture a web part page with "capture" function, I reach the following error message
Unable to fetch site <sharepoint web page url>.Error # 401
Any idea ?
