we have the situation, that some globals and dictionaries are shared between applications. If I export an application all other applications, which use the same dictionaries, are exported too. At least I believe that the dictionaries are the case. This applies to the current version 2020.1.3.441.
Of course, I can uncheck the unrelated applications, but this is error prone.
In my opinion the applications are not related, if they only share elements defined in system settings, data sources or plugins. Examples:
-- business rules
-- form rules fields
- Data source
If the export hits one of these elements no further related elements should be gathered.
