In the IMG (SOLMAN_CM_IMPT_AUTH), there is a note describing necessary roles for import actions.
Add Import Authorization to Operator/Administrator
Change Request Management uses the import functions of the Transport Management System (TMS). The TMS remote infrastructure is based on RFC connections that point solely to the 000 client of a target system. The operator and administrator users need to have import authorization for client 000 of all target systems.
1. Make sure that the operator and administrator users in client 000 of the target systems have the same name as their user in the Solution Manager system.
2. Assign import authorization to the operator and administrator users in client 000 of the target systems (SAP_CHANGEMAN_OPERATOR and SAP_CHANGEMAN_ADMIN roles).
For more information about import authorizations and the trusted systems concept, see Configuration Guide: SAP Solution Manager 4.0, and the online documentation for Change Request Management.
Here I have 2 questions. Assume that I have the following SAP landscape.
DEV QA PRD
100 --> 150 --> 200
Do I need to assign the import role to a user in client 150 of QA in additon to a user in client 000?
I assume that only a user in client 000 need import role. Am I right?
What if a user in clinet 150 of QA has import role and a user with same name does not exist in client 000? Will import be executed or not?
I searched relevent SAP notes but not information was found.
