To open the Structure Viewer, right-click the port and select Edit Structure from the pop-up menu.
To add an attribute to the port structure
Click the line number of the line where you want to insert the attribute. The current and following attributes will shift downward.
Click Add Attribute, or select Actions | Add.
Enter a name for the attribute. The names for port attributes must start with an alpha character and can contain only alphanumeric characters (A-Z, 0-9).
Enter a datatype.
Enter a size.
Enter additional specifications.
To delete an attribute from the current port structure, select an attribute line number and click Delete, or select Actions | Remove.
When you modify datatypes of a record structure, you modify the internal logical representation that Sybase ETL uses for the record structure during your transformation. This does not going change the data structure definition of the source or destination tables. You must make sure that the data structure of the final Data Sink is compatible with the content you are generating. If you are using the Standardize Data Format option, make sure that the datatype you are assigning to the port attribute matches the type of your target attribute.
