Attachment Levels Are Not Hierarchical

Before attaching Device User Source, it is important for you to understand what each of the four device user source attachment levels cover.

• Device (device-level attachment)
• Screen/Report (screen- or report-level attachment)
• Format (format-level attachment)
• Entry (entry-level attachment)

The attachment levels do not form a hierarchy. For example:

• Attaching a section of device user source at format-level does not enable it over a field within that format.
• Attaching device user source at device-level only has relevance at device-level, not at any lower level.

Note: This discussion does not apply to the field attachment level, which provides a generic way to apply user source to all derived entries for a field.
