... LINES OF jtab [FROM idx1] [TO idx2] [USING
KEY keyname]
What does it do? The rows of an internal table jtab are added as a
block. jtab is a functional
operand position .
The inserted rows are sequentially taken from the table jtab .
The row type of jtab can be incompatible with the row type of the
internal table itab and it is converted to the row type of the
target table (if necessary), in accordance with the
conversion rules .
The order in which the rows are taken is the same as for the statement
LOOP and can also be influenced by
specifying a table key keyname after
USING KEY . The additions FROM idx1 and TO idx2 have, in
relation to jtab , the same syntax and effect as for
LOOP .
Latest notes: If a conflict with existing primary or secondary table keys
occurs, this always raises a non-handleable exception when multiple rows
are appended.
