—   INDEXES_IN_DB_NOT_IN_AOT

— ————————————————————–
— Find INDEXES that are not defined in the AOT

—  NOTE: Ignore System tables in this list.

— INDEXES should ALWAYS be defined in the AOT as synchronization
—   will remove them

— This also violates Dynamics AX Best Practices to not have an
— index defined in the AOT !!

— It’s ok to add an index for testing purposes on the SQL side
—  as long as you add it to the AOT once you know you are going
—  to keep the index

— ————————————————————–
— Find INDEXES that have RECVERSION in the Key or Included list

— ————————————————————–
— Find tables that don’t have a unique key for AX record caching
— Can’t record cache w/o a unique index on the table
— You must define a unique index and use that filter in X++ code
