A synchronous request is a type of request that Siebel Open UI sends to the Siebel Server, and then waits for a reply to this request before it continues any other processing.

The GetSelection request is synchronous, so Siebel Open UI cannot send another request to move the selection to a different record before the Siebel Server sends a reply notification that indicates a successful deletion. When processing this notification, the intended row is the same row that Siebel Open UI most recently selected. Siebel Open UI can use the selected row as a common index that it can use to reference the record.
