How To Fix SABP_KEY_REDUNDANCY006 - &1 is non-unique, &2 is unique

SABP_KEY_REDUNDANCY006 - Overview

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 006

• Message text: &1 is non-unique, &2 is unique

What causes this issue?

The table keys &V1& and &V2& are both of the type SORTED. The non-unique
key &V1& is an initial part of the unique key &V2&. Check whether both
keys are required.
INCLUDE INCL_MIGRATION_SCENARIO
The key &V2& has more components than &V1& and is thus more selective.
In the case of all statements where the key &V1& is used, &V2& could
also be used (exception: READ/DELETE # WITH TABLE KEY#, where all key
components have to be assigned exactly).
Check whether only one of the keys is used or could be used and whether
the other key can therefore be removed.
