COLLECT - result
Other versions: 7.31 | 7.40 | 7.54
Syntax
... { ASSIGNING <fs> [CASTING] }
| { REFERENCE INTO dref }.
Effect
The addition ASSIGNING is used to assign the inserted or existing row to
a field symbol <fs> and the addition REFERENCE INTO is used to set a reference to the row in a reference variable.
The syntax and meaning are the same as when specifying the output behavior in the statement
READ TABLE and the same restrictions apply regarding the modification of key fields for
primary and
secondary table keys.
In particular, inline declarations using the declaration operators
DATA and FIELD-SYMBOL are possible.
Example
The statement COLLECT is executed until the column num reaches the value 100 for one of the three possible key values.
TYPES:
BEGIN OF line,
key TYPE c LENGTH 1,
num TYPE i,
END OF line.
DATA
itab TYPE SORTED TABLE OF line
WITH UNIQUE KEY key.
DATA(rnd) = cl_abap_random_int=>create( seed = + sy-uzeit
min = 1
max = 3 ).
DO.
COLLECT VALUE line( key = COND #( LET r = rnd->get_next( ) IN
WHEN r = 1 THEN 'X'
WHEN r = 2 THEN 'Y'
WHEN r = 3 THEN 'Z' )
num = 1 ) INTO itab
ASSIGNING FIELD-SYMBOL(<fs>).
IF <fs>-num = 100.
EXIT.
ENDIF.
ENDDO.
cl_demo_output=>display( itab ).
