CNV_00001542 - Overview

• Message type: E = Error

• Message class: CNV_00001 - Message class for CWB settings maintenance programs

• Message number: 542

• Message text: No data to restore table &1 could be found.

What causes this issue?

No data to restore table &V1& could be found in the system.
To be able to restore a table the system has to contain data from the
table from before the conversion. There are generally 2 different
sources of such data possible:
explicit backup performed before the conversion
data stored during the selection phase of the conversion
The first source (backup) is the preferred one, because it is always
possible to restore table contents using this data source. Backup,
however, must be explicitly performed manually before the conversion
(before you know that something goes wrong).
The data stored in the selection phase of the conversion is normally
always available, but it is not always possible to use it to restore the
contents of the table (depending on the conversion scenario the data
might or might not contain enough information to perform such restore).
