Attachment Name
Use this field to specify the name by which this document is identified within the application event system. This field is used with the Update and Detach actions and is optional for the Attach and Link actions.
If this value is not specified for these actions, a default value is constructed by concatenating the Document Name with the Document Sequence, separated by a period; for example, MyDocument.000000001
The contents of this field must use this syntax:
scalarExpression
where scalarExpression is or resolves to a properly formatted attachment name value.
When you click Event Actions form, the system "wraps" this content within an ATTACHMENTNAME( ) parameter, which yields this final syntax:
to return to theATTACHMENTNAME(scalarExpression)
