Solman Managed Systems - 7 Create Users

Dear experts,

I am trying to configure Solution manager 7.1.

I am at Managed Systems>>7. Create Users

(The managed system is Solman itself)

There are 4 steps at this point.

I get the following error:

User ... is not allowed to perform this request. Check SAP Note 1647157.

Note 1647157 - How to Set up Access to the SPML Service on AS Java

In this note it is stated that I need to create some role, but I do not have such option.

Could you please shortly give some hint? Am I missing something?

Regards,

Shkelzen
