Registering a Delimited External File

Right-click the destination folder for the external file metadata. Then, select NewExternal FileDelimited to access the General page in the New User Written External File wizard. Enter an appropriate name and description of the external file that you want to register. Click Next to access the External File Location page.

If you are prompted, enter the user ID and password for the default SAS Application Server that is used to access the external file.

Specify the physical path to the external file in the File name field. Click Next to access the Delimiters and Parameters page.

Select the check box for the appropriate delimiter in the Delimiters group box. Accept the default values for the remaining fields, and click Next to access the Column Definitions page.

Click Refresh to view the raw data from the external file in the File tab in the view pane at the bottom of the page. Sample data is shown in the following display.

Click Auto Fill to access the Auto Fill Columns window and populate preliminary data into the columns component of the Columns Definition page.

The first row in most external files is unique because it holds the column names for the file. Therefore, you should change the value that is entered in the Start record field in the Guessing records group box to 2. This setting ensures that the guessing algorithm begins with the second data record in the external file. Excluding the first data from the guessing process yields more accurate preliminary data.

Accept all of the remaining default settings. Click OK to return to the Column Definitions page.

Click Import to access the Import Column Definitions window and the import function to simplify the task of entering column names.

Select the Get the column names from column headings in the field radio button, and keep the default settings for the fields underneath it. Click OK to save the settings and return to the Column Definitions page. The names from the first record in the external file are populated in the Name column. You now can edit them as needed.

The preliminary metadata that is populated into the columns component usually includes column names and descriptions that are too generic to be useful for SAS Data Integration Studio jobs. Fortunately, you can modify the columns component by clicking in the cells that you need to change and entering the correct data. Enter appropriate values for the external file that you are registering. The following display depicts a sample completed Column Definitions page.

To verify that the metadata you have entered is appropriate for the data in the external file, click the Data tab and then click Refresh. If the metadata matches the data, the data is properly displayed in the Data tab. The Data tab looks similar to the View Data window for the registered external file. If the data does not display properly, update the column metadata and click Refresh to verify that the appropriate updates have been made. To view the code that is generated for the external file, click the Source tab. To view the SAS log for the generated code, click the Log tab. The code that is displayed in the Source tab is the code that is generated for the current external file when it is included in a SAS Data Integration Studio job.

Click Next and then Finish to save the metadata and exit the delimited external file wizard.

Right-click the external file, and click Properties. Then, click the Columns tab. The Columns tab is displayed, as shown in the following display.

Click OK to save any changes and close the properties window.
