We are using SAP Integrated ITS 640 . We have configured the PDF printing device as mentioned in the SAP Note # 771683 . We have configured SSO in portal for r/3 system and SSO works fine in portal for Internet services configured in backend but when i give print by selecting PDF printer as output device, ITS is prompting for r/3 user id and password at that time to view the PDF. Once i give r/3 user id and password ,i am able to view the PDF.
I found out that when PDF popup window opens it opens the HTTP url and not with the HTTPS url configured in the System configuration in portal. I feel this is the reason why i have been asked to enter user id and password. So could any one please let me know how to configure in R/3 backend to use the https url for PDF printing.
