Hi ​@Udanee ,

I could find below help text for Ledge Assistant field in Apps 10.

Hope it will be helpful for you.

“Ledger Assistant:
The ID of the default ledger assistant of the company, who would direct certain event messages to the application users. It is possible to override this value with the settings on the event action. The ledger assistant should be a person defined in the Person window, and also must be defined as a user for the company in the Users Per Company window.”

Regards,
Kethaka

Thanks a lot Kethaka.
