RE: Users that represent an application must have license type "external"
Hello Marco,
Thank you for your reply. I solved issue by changing application ID field into {00000000-0000-0000-0000-000000000000} for related user on users table. Then I was able to change "License Type" into "Full User"
I have noticed that new users have application ID as {00000000-0000-0000-0000-000000000000}. So, I think user cards got these ID's before BC Upgrade(This customer was upgraded from NAV 2016 to BC). I'm not sure this is my comment after some observations.
Best regards,
Okan Abat
