What causes this issue?

Before the installation, the system always checks the tables to be
installed. The errors found in the check are so serious that an
installation should not be performed before the errors have been
corrected.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Revise your table definition.
If you still want to install despite the errors, you can try to do so
again using the function 'Force installation'. However, it is only
then possible to perform an installation if certain basic requirements
are met with regard to the table definition.
