Issue with Logon Ticket SSO

Hi All!!!

I´m trying to fix a Logon Ticket SSO between an ERP2005 and an EP7.

I go to the RZ10 transaction, because I need to modify the value of the "login/accept_sso2_ticket" and "login/create_sso2_ticket" parameters on the Profile Instance, but these parameters are not in the parameter list.

Besides, when I check the Profile, I get a popup saying that there are incorrect parameters.

Must I configure anything previously?

Helpful answers will be rewarded.

Thanks and regards,

Manuel Míguez.
