SAP Error Message - Details

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 009

• Message text: Keys &1 and &2 are both 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 be removed.
