Lazy Update
Procedure to create or update non-unique secondary table keys of
internal tables. Non-unique
secondary tables keys are not updated straight after insert operations using
INSERT, or APPEND,
or a block operation in which the whole table body is filled at once, or after a operation using MODIFY, or via
field symbols, or
data references. They are updated at the next explicit usage. See also
direct update and delayed update.
