About the Main Windows and Wizards Job Status Icon 15 Change management options are available from the Project drop-down menu and from pop-up menus. See also “Process Library” on page 23. Default SAS Application Server This pane displays the default SAS application server, if you have selected one. The message No Default Application Server indicates that you need to select a default SAS Application server. If you double-click this pane, the Default SAS Application Server window opens. From that window, you can select a default server or test your connection to the default server. Alternatively, you can select the default SAS application server from the Options window, as described in “Options Window” on page 19. For more information about the impact of the default SAS application server, see “Selecting a Default SAS Application Server” on page 96. User ID and Identity This pane displays the domain, login user ID, and metadata identity that are specified in the current metadata profile. Metadata Server and Port This pane displays the name and port of the SAS Metadata Server that is specified in the current metadata profile. Job Status Icon You can right-click this icon to display a list of the last five unique jobs that were submitted in the current SAS Data Integration Studio session and the status for each of them. Note: The appearance of the icon changes to indicate changes in the status of the jobs that you submitted in the current session. The icon appearance returns to normal when you right-click the icon. 16 Expression Builder Window Chapter 3 Expression Builder Window Use the Expression Builder to create SAS expressions that aggregate columns, perform conditional processing, and perform other tasks. For example, the following display shows an expression that sums the values in a column named Total_Retail_Price. Display 3.2 Expression Builder Window with a SUM Expression The Expression Builder is displayed from tabs in the property windows of many SAS Data Integration Studio transformations. For an example of how the Expression Builder can be displayed and used in the context of a job, see “Change One Column to a Calculated Column” on page 157. The Expression Builder is used to add or update expressions in SAS, SQL, or MDX. The expression can transform columns, provide conditional processing, calculate new values, and assign new values. The expressions specify the following elements, among others: column names SAS functions constants (fixed values) sequences of operands (something to be operated on like a column name or a constant) and operators, which form a set of instructions to produce a value An expression can be as simple as a constant or a column name, or an expression can contain multiple operations connected by logical operators. For example, an expression to define how the values for the column COMMISSION are calculated could be amount About the Main Windows and Wizards Open a Metadata Profile Window 17 * .01. An example of conditional processing to subset data could be amount > 10000 and region = ’NE’ . Other examples could be an expression to convert a character date into a SAS date or an expression to concatentate columns. For details about SAS expressions, see SAS Language Reference: Concepts in SAS OnlineDoc. Job Properties Window Use the properties window for a job to view or update its basic metadata. For example, you can specify whether the code for the current job will be generated by SAS Data Integration Studio or will be retrieved from a specified location. You can also use this window to specify code that should be run before or after a job executes. The following display shows a typical window. Display 3.3 Job Properties Window If you want to specify user-written code for the Sort Staff job that is described in “Process Flows and Jobs” on page 6, you can enter metadata that is similar to the metadata that is shown in the previous display. In the job properties window shown in the previous display, the User written option has been selected, and the physical path to a source code file has been specified. If you wanted to execute code before or after the Sort Staff job is executed, you can click the Pre and Post Process tab and specify the code. For example, you might want to issue a SAS LIBNAME statement before the job is run. For a summary of how to use the job properties window, see “Updating Metadata for Jobs” on page 105 and “Viewing Metadata for Jobs” on page 111. Open a Metadata Profile Window A metadata profile is a client-side definition of where a metadata server is located. The definition includes a host name, a port number, and a list of one or more metadata repositories. In addition, the metadata profile can contain a user’s login information and instructions for connecting to the metadata server either automatically or manually. 18 Open a Metadata Profile Window Chapter 3 When you start SAS Data Integration Studio, the Open a Metadata Profile window displays in front of the desktop. The following display shows an example of this window. Display 3.4 Open a Metadata Profile Window Use the Open a Metadata Profile window to open an existing metadata profile, edit an existing metadata profile, or add a new metadata profile. You must open a metadata profile before you can do any work in SAS Data Integration Studio. About the Main Windows and Wizards Options Window 19 Options Window Use the Options window to specify options for SAS Data Integration Studio. The following display shows an example of this window. Display 3.5 Options Window The Options window contains the following tabs: General specifies general user interface options for SAS Data Integration Studio, such as desktop colors or whether to show the SAS Log tab in the Process Designer. Process specifies options for the Process Editor tab in the Process Designer. These options control how process flow diagrams display. Editor specifies options for the Source Editor tab in the Process Designer. These options control the appearance and behavior of the Source Editor. Metadata Tree specifies what types of metadata are displayed in the Metadata tree on the SAS Data Integration Studio desktop. SAS Server specifies the default SAS application server for SAS Data Integration Studio. Data Quality specifies options for Data Quality transformation templates that are available in the Process Library tree. View Data specifies options for the View Data window that is available for tables, external files, and selected transformations. Code Generation specifies options for code generation and parallel processing. . Source Editor.
