I upgrade to the rollup 12.
Now, can't re-assign any entity to a user.
The log shows no error, just
does not save the changes.
Does anyone have the same problem?
Finally i have an error in the installation log.
The error message in our log stated, that the setup tries to convert a varchar
field in the database into a datetime field.
My default language for SQL database and CRM is Spanish.
To complete the intallation i had to change the sql language to english,
after the installation was done correctly.
