2985430 - SQL optimization and index usage


A query has a WHERE clause and therefore, ADS creates automatically an Advantage Optimized Filter (AOF). However, ADS does not use existing indexes for optimizing that AOF.

The warning message is:

Restriction is not fully optimized. 
Unoptimized Part: REFERENCE="1234.12.12"

But there are two indexes, IDX_ALT_REF and primary key, that could be used.
