LOOP AT itab

Reference

Syntax

LOOP AT itab { { INTO wa }
             | { ASSIGNING <fs> [CASTING] }
             | { REFERENCE INTO dref }
             | { TRANSPORTING NO FIELDS } }
             [USING KEY key_name|(name)]
             [FROM idx1] [TO idx2] [WHERE log_exp|(cond_syntax].
  ...
ENDLOOP.

Effect

Reads an internal table itab in a loop. A restricted variant works with mesh paths.

Additions

• INTO wa
  Assigns the read line to a work area wa.

• ASSIGNING <fs> $[CASTING$]
  Assigns the line read from internal table to a field symbol <fs>, where casting can be performed.

• REFERENCE INTO dref
  Assigns a reference to the line read from internal table to a reference variable dref.

• TRANSPORTING NO FIELDS
  Does not assign the read line.

• USING KEY key_name$|(name)
  Statically or dynamically specifies a (secondary) table key that determines the processing order.

• $[FROM idx1$] $[TO idx2$] $[STEP n$] $[WHERE log_exp$|(cond_syntax)$]
  Restricts the lines to be read, by declaring a lower number and upper number (idx1 and idx2 in the relevant table index), by defining the step size and the direction of a loop (value of n), or by declaring a static condition log_exp or a dynamic condition in cond_syntax.

• GROUP BY ...
  Groups the lines in the internal table by a group key and executes a loop across the groups. ASCENDING$|DESCENDING sorts the groups; WITHOUT MEMBERS suppresses the grouping variant for the table lines; INTO GROUP, ASSIGNING, and REFERENCE INTO define the output behavior of the group loop.
