where condition error when loop through a C itab

[former_member625844]

I wrote below code.

DATA:kstar_t TYPE STANDARD TABLE OF kstar .

LOOP AT kstar_t TRANSPORTING NO FIELDS WHERE kstar <= '89999999' AND kstar >= '8000000' .

ENDLOOP.

I want to check in table kstar_t whether exist data in some range. But it has error "kstar has no structure so do not have a component kstar". So what's the correct way to loop where in a single field table? Thx.

You have 2 types of internal tables, those with lines which are structures containing components (field names), and those without component -> usually the "pseudo-component" TABLE_LINE can address the whole line:

DATA:kstar_t TYPE STANDARD TABLE OF kstar .

LOOP AT kstar_t TRANSPORTING NO FIELDS WHERE table_line <= '89999999' AND table_line >= '8000000'.

ENDLOOP.

You need to create a proper table type:

TYPES:
  BEGIN OF ty_kstar,
    kstar TYPE kstar,
  END OF ty_kstar.
  
 TYPES:
   tt_kstar TYPE STANDARD TABLE OF ty_kstar.
  
 DATA:
   t_kstar TYPE tt_kstar.
  
 *...
  
 LOOP AT t_kstar INTO DATA(s_kstar) WHERE kstar BETWEEN '8000000' AND '89999999'.
*  Do something.
 ENDLOOP.
