An active unmanaged layer is created after you import a managed solution
Applies to: Power Platform, Solutions
Symptoms
After you import a managed solution, an active unmanaged layer is created.
Cause
During solution import, the system must ensure that there's a fallback form for a table. This requirement is enforced when you create tables or forms. If no fallback form is specified for a table during import, the system creates an unmanaged active layer for one of the main forms, and the unmanaged customization indicates the form as the fallback form. This ensures that users can view a form when they don't have access to any other table forms.
Workaround
To work around this issue, make sure that the table has a fallback form before you export the unmanaged solution as managed for import. For more information, see Set the fallback form for a table.
