Fiori My Inbox Open Task throwing System alias RDACLNT110_PGW does not exist

Hi Experts,

Recently I have changed the custom workflow in s/4hana , after changes I tried to select the "Open Task" option of the Non Po invoice work item, but it's throwing an error as System alias RDACLNT110_PGW does not exist.

In FDA100 client I have created the ZTASKPROCESSING service using tcode /IWFND/MAINT_SERVICE with RDACLNT110_PGW alias name, alias name contains the RFC destination pointing to RDACLNT110.

Am I supposed to do any configuration changes, please let me know how to fix the issue.
