LOOP AT itab - result

Syntax

... { INTO wa }
  | { ASSIGNING <fs> [CASTING] }
  | { REFERENCE INTO dref }
  | { TRANSPORTING NO FIELDS } ... .

Effect

You have four alternatives to influence the display:

• With the addition INTO, you assign the content of the current line to a work area wa.
  
  
• With the addition ASSIGNING, you assign the current line to a field symbol <fs>; within the loop, you are not allowed to assign a different memory area to the field symbol or cancel the assignment with UNASSIGN.
  
  
• With the addition REFERENCE INTO, you set a reference to the current line in a reference variable (since release 6.10).
  
  
• With the addition TRANSPORTING NO FIELDS, you only fill the corresponding system fields. This addition is only possible, if the addition WHERE is used simultaneously in the conditions cond.
  

With the one exception, that behind INTO wa there is no further specifiction of transport_options, the syntax and meaning of the specification of the display behaviour are the same as in the statement READ TABLE. Additionally, there are the same limitations regarding the manipulation of key fields as with sorted tables and hashed tables.

Note

At LOOP, you can omit the specification INTO wa outside of classes if the internal table has a homonymous header line itab. The statement is then amended by INTO itab.
