Specifying Dynamic URL ID Attachment Properties

With a dynamic attachment type, all the components of a URL are generated from the value in query field. With a dynamic attachment type, much of the information related to the attachment is unknown prior to the transaction occurring.

For example, with a static attachment type, it is known beforehand what the URLID will be, so it can be specified when the attachment properties are set. With a dynamic attachment type, the values of the attachment properties are determined at the transaction time, and the property values, such as URLID, file reference path, and attachment file name, are stored in the row of data associated with the attachment. The attachment property values can vary between rows.

This example illustrates the fields and controls on the Define Attachment Properties: Dynamic URL. You can find definitions for the fields and controls later on this page.
