Try publish in SR of CE from Netweaver 2004s(700)

Hello all

When I use WSPUBLISH transaction in my netweaver 2004s stack, I receive the following messages :

Green : Services registry Name : SR_UDDI_ Logical port LP_SR_ERP

Green : Services registrsy versions is 1.0

RED : No publication possible from Integration Server(IS)

Of course the RED message is boring me, I certainly forget something, but I didn't found any related post for this message, can someone help please ?

Thanks
