The Open dialog is divided into two areas. The identifiers and object types (icons) are listed on the left and the associated objects are displayed on the right.
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.)
