PowerBuilder DataWindow Extended AttributesLocate this document in the navigation structure

When designing tables to be used in a SAP® PowerBuilder® DataWindow, you can manage the extended attributes which PowerBuilder uses to store application-based information, such as label and heading text for columns, validation rules, display formats, and edit styles.

PowerDesigner supports the modeling of this information through an extension file. To enable the PowerBuilder extensions in your model, select Start of the navigation path Model Next navigation step Extensions End of the navigation path, click the Attach an Extension tool, select the PowerBuilder file (on the General Purpose tab), and click OK to attach it.

When this extension file is attached, additional properties for two PowerBuilder system tables (PBCatTbl for tables and PBCatCol for columns) are available on the PowerBuilder tab of tables and columns:

Select the tables you want to reverse-engineer, and click OK.

To update the PowerBuilder extended attribute system tables in your database, select Start of the navigation path Tools Next navigation step PowerBuilder Next navigation step Generate Extended Attributes End of the navigation path, click the Connect to a Data Source tool, select a machine or file data source and click Connect. Select the tables you want to generate, and click OK. Reversed extended attributes are compared with the translated default values in the PowerBuilder extension file. If these attributes match, the reversed value is replaced by the default value from the extension file.
