type TABLE how modify the value of a field

[Former Member]

Hi,

how can I modify a the value of a field if the type is type table ? Usually you can

say e.g.

*MODIFY ET_ITEM FROM <fs_wa> TRANSPORTING BE_LOG_SYSTEM.

But you will get the error in has not a componenet like 'BE_LOG_SYSTEM'

because it has the type type table

data  ET_ITEM type table.
field-symbols:         <fs_wa>   TYPE data.
FIELD-SYMBOLS:    <fs_logsyst>.


DATA dy_row type ref to data.
create data dy_row like line of ET_ITEM.
assign dy_row->* to <fs_wa>.   

LOOP AT ET_ITEM ASSIGNING <fs_wa>.
ASSIGN COMPONENT 8 OF STRUCTURE <fs_wa> TO <fs_logsyst>.
IF <fs_wa> IS ASSIGNED.
 <fs_logsyst> = 'E77CLNT200'.
*MODIFY ET_ITEM FROM <fs_wa> TRANSPORTING BE_LOG_SYSTEM.
ENDIF.
ENDLOOP.

Hi

U don't need any MODIFY statament, the field-symbol is just a pointer only, so when the value of field-symbol is changed, the value of variable assigned to the field-symbol is changed too:

LOOP AT ET_ITEM ASSIGNING <fs_wa>.
   ASSIGN COMPONENT 8 OF STRUCTURE <fs_wa> TO <fs_logsyst>.
    IF <fs_wa> IS ASSIGNED.
       <fs_logsyst> = 'E77CLNT200'.
   ENDIF.
ENDLOOP.
