The Open dialog is divided into two areas. A list includes the identifiers and object types (icons) and another list displays the associated objects.
The list of objects varies depending on the identifier you select.

Use a Pattern to limit the list of requests in the Open dialog. A Delete Request name consists of two parts: identifier.name. The Pattern must also have two parts. You can use the % (percent) wild card to represent one or more characters or use the _ (underscore) wild card to represent a single character in an object definition name. (The underscore must be selected as the SQL LIKE character on the General tab of Personal Options.)
