What causes this issue?

The generated structure &V1& is used in database tables that already
contain data. The current generation run discovered that the structure
of table &V1& (logical name &V4&) has been changed. To prevent data
corruption, the system has created a new structure with the name &V2&.
This structure corresponds to version number &V3& for logical object
&V4&.
<ZU>The system is now in an inconsistent state!</>

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?

To restore consistency, the data in table that uses structure &V1& must
be converted to new tables that use the new structure &V2&. If these
data-filled tables are not generated for a consolidation area, you must
create the new tables yourself in the Data Dictionary.
