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