HI Balajee
In Customizing activity "Define Inbound Processing for E-Mails", it is stated that the PFCG role SAP_EHSM_HSS_INCIDENT_EML_REC has to be assigned to the user SAPCONNECT. However, if you have assigned another system user already for the e-mail configuration instead of SAPCONNECT, the functionality will not work.
You have assigned the PFCG role SAP_EHSM_HSS_INCIDENT_EML_REC to the user that processes incoming e-mails (default user is SAPCONNECT).
"This role contains the authorization profiles(check your basis team , they will tell you profile details) needed to receive and process e-mails. You can find the user ID that is assigned as the user for processing incoming e-mails in the SMTP Host node in transaction SICF."
Check and update me.
