SOLMAN 7.1 CRM UI - "Reported By" Empty

Hi Experts,

I am currently on SOLMAN 7.1 SP10, configuring Service Desk.

The "Reported By" field is not getting populated if i directly create incident in CRM UI (tcode: SM_CRM or using direct link).

The best part is, if I create incident from any Managed Systems (Help--> Create Support Message), the "Reported By" field is populated

So, this should not be any problem with Business Partner setup (as highlighted by many SCN links).

I suspect, I might have missed out any config, but something tells me its "Access Sequence" (but there are no guide on this anywhere)

I did go thru the wizard, but i dont understand anything. This suppose to be easy for people out there.

Below are all my screenshots for "Partner Determination Procedure"

Appreciate experts help (this is my first post in SCN )

i have added some parameters here (DNO_CUST4), such as below, please do advise if these are appropriate / related to this issue.

Thanks

Regards

Shahul
