How to export computed fields
There are 3 different types of Computed fields:
“Computed” and “Computed when composed” are part of Notes backend document and therefore will be part of a XML metadata.
As for “Computed for display” fields, they are not part of the Notes backend and therefore will not be part of metadata XML either.
For “Computed for display” type fields to be included in metadata XML, custom metadata needs to be created.
