Message class: SAUL_ATC_CHECKS - Upgrade ATC Checks
Message number: 001
Message text: Index ID '&1' is transformed during an upgrade to '~&2' or '^&2'
The name of a secondary index of a database table in the ABAP Dictionary
may have 18 characters at most. It consists of the database table name
and an index ID with up to 3 characters. Database tables whose name
consist of 16 characters may cause problems during an upgrade <ZH>for
the following reason</>:
During an upgrade, the system generates shadow tables and adds to their
index name an additional single delimiter (~ or ^).
Table name &V3& consists of 16 characters and index ID '&V1&' will be
shortened to '~&V2&' or '^&V2&' for the shadow table to the index name
&V3&~&V2& or &V3&^&V2&.
This collides with the name of the primary index &V3&~0 or &V3&^0.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Choose another ID for the secondary index that is not truncated to '0'
for the shadow table.
