solicited and unsolicited

Imported from previous forum

can anyone give me clear picture for solicited and unsolicited .
exactly whats happens with these order

“Solicited” or “unsolicited” refer to the nature of the interaction with the client at the time that the order was placed. They don’t drive order handling and/or execution. These trade facts would typically need to be persisted through the lifecycle of a trade in order to drive downstream processes (e.g., disclosure on a trade confirmation).
