When using "Copy into legal entity" data project, entity: Bill of materials headers and versions V3, the copy job fails when a BOM Header changed, like date range, quantity, etc.

Error message: Function is not supported.

It's supported as per Microsoft documentation:

The process resembles an export and import that occur in one step. As in an import, if information that exists in the source legal entity doesn't exist in the destination legal entity, the copy process adds it. If information already exists in the destination legal entity, the copy process updates it.
