Help with OBJECTS_NOT_CHARLIKE dump

[walkerist]

Hi, I'm having an issue reading the string length of the value of a BSAK field.
I'm having issue specifically on the field MWSTS.

My code is :

FIELD-SYMBOLS: <ls_field> TYPE ANY.
SELECT *
FROM BSAK INTO TABLE @DATA(it_bsak).
DATA(v_lines) = lines( it_bsak )
DATA(ls_bsak) = it_bsak[ v_lines ]
ASSIGN COMPONENT sy-tabix OF STRUCTURE ls_bsak to <ls_fields>.
IF <ls_field> IS ASSIGNED.
  DATA(v_length) = strlen( <ls_field> ).
ENDIF.

Hello walkerist

STRLEN works for strings or character-like fields. Your code tries to apply STRLEN to all the fields of BSAK. Some of them are not character-like, hence the dump. For instance BSAK-MWSTS is the amount field - you can apply STRLEN to it.

Best regards

Thanks everyone, I have declared a field to pass the LS_FIELD.
Here's the modified code:

DATA: v_field(100) TYPE C.
FIELD-SYMBOLS: <ls_field> TYPE ANY.
SELECT *
FROM BSAK INTO TABLE @DATA(it_bsak).
DATA(v_lines) = lines( it_bsak )
DATA(ls_bsak) = it_bsak[ v_lines ]
ASSIGN COMPONENT sy-tabix OF STRUCTURE ls_bsak to <ls_fields>.
IF <ls_field> IS ASSIGNED.
  v_field = <ls_field>.
  DATA(v_length) = strlen( v_field ).
ENDIF.

Your code is very confusing: <LS_FIELD> is not initialized, <LS_FIELDS> is not declared, SY-TABIX is not initialized...
