Authentication for open Payload

Hello togehter,

I have a problem with the authentication roles in SAP NW 7.4.

I search for a role which only allow to open the payload of a message.

I try it with all actions i can find, but i get always the error i hvae no authentication fpr payload openening.

At SDN or at the help i didn´t find anything about it.

Can you please help me and tell me a right role for my issue.

Thanks.
