Table index
An index of an
internal table , administrated by the
ABAP runtime environment . There is
a primary table index for
index tables and
secondary table indices for the
administration of sorted
secondary table keys . The line
numbers of every table index start at 1 and run consecutively and with
no gaps, up to the current number of rows in the table. If necessary,
the physical index is changed to a logical index, which causes an
increased runtime demand. The logical index is created in precisely the
moment in which a row is inserted before another row, the sequence of
table rows is changed, or if any row except for the bottom row is
deleted.
