No System Alias Assignment and GSDO Group Maintained(when moved Dev to Test system)

Hi Experts,

I have developed a custom gateway project and service registration, maintenance done and it is working properly in Dev system, Now the TRs containing the objects have been moved to QA system which has same clients.

Gateway System details: SAP Gateway 7.40 and SP11.

Problem: When I access t-code /IWFND/MAINT_SERVICE in QA and selected my service, I am getting below information and there are no entries in table /IWFND/C_MGDEAM.

Log:No System Alias found for Service 'XXXXXXXX' and user 'XXXXXX'

So what went wrong I am not sure, please help me what to do in this case.

I am thinking this is because of some Authorization while moving from one system to another system(same landscape). Could this be the reason?

Thanks and Regards
