Hello,

I dont think that there is any function available for this.

A few lines of code & thats it.

DATA:
V_TRUE TYPE FLAG,
V_LEN TYPE I,
V_LINES TYPE I.

CLEAR: V_LEN, V_LINES, V_TRUE.

V_LEN = STRLEN( V_INPUT ). 

SPLIT V_INPUT AT '-' INTO TABLE ITAB.

V_LINES = LINES( ITAB ).

"If true, then V_LEN = 7 & V_LINES = 2
IF V_LEN = 7 AND V_LINES = 2.
V_TRUE = 'X'.
ENDIF.

BR,

Suhas

Hi, Qwart

As i understand your requirement, you need the following, Test the code given bellow and revert me back if any else requirement.

PARAMETERS: string TYPE string.
DATA: ans(1).

PERFORM: check_string USING string ans.

WRITE: ans. " Here it will write T or F ( T for True and F for False )
*&---------------------------------------------------------------------*
*&      Form  check_string
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
*      -->VALUE(STR) text
*      -->FLAG       text
*----------------------------------------------------------------------*
FORM check_string USING value(str) flag.

  DATA: sub_str1 TYPE string,
        sub_str2 TYPE string,
        slen TYPE i,
        sub_slen1(7),
        sub_slen2(7).

  slen = STRLEN( str ).

  IF slen = 7.
    FIND FIRST OCCURRENCE OF '-' IN str.
    IF sy-subrc = 0.
      SPLIT: str AT '-' INTO sub_str1 sub_str2.
      FIND FIRST OCCURRENCE OF '-' IN sub_str2.
      IF sy-subrc = 0.
        flag = 'F'.
      ELSE.
        flag = 'T'.
      ENDIF.
    ELSE.
      flag = 'F'.
    ENDIF.
  ELSE.
    flag = 'F'.
  ENDIF.
ENDFORM.                    "check_string

Hi,

From the below program logic you can create the FM

****************************************

data: v_len type i,v_return(1) type c value 'F'.

parameters: P_string type string.

v_len = strlen( p_string ).

if len = 7.

if p_string CO '-'.

v_return = 'T'.

endif.

write : v_return,len.

********************************************

Hope this will help you.

HI,

You may use this :-

data len type i.

data str type string .(String to be checked)

len = strlen( str ).

if len = 7.

FIND - IN SECTION OFFSET off OF

str

endif.

data s1 type string value 'asdf-dfgd-234-asd'.
data: d1 type i,l1 type i.
d1 = strlen( s1 ).
DATA : res_tab TYPE MATCH_RESULT_TAB,
       res TYPE MATCH_RESULT.
find ALL OCCURRENCES OF '-' in s1 RESULTS  res_tab .

DESCRIBE TABLE res_tab LINES l1.
WRITE : 'length:', d1, ' occurance:', l1.

Hi,

try this:



DATA: I_STRING TYPE STRING VALUE '-------'.
DATA: L_STRING TYPE I.
*
L_STRING = STRLEN( I_STRING ).
*
IF L_STRING = 7 AND I_STRING = '-------'.
  WRITE: 'OK'.
ELSE.
  WRITE: / 'ERROR'.
ENDIF.

*"  EXPORTING
*"     REFERENCE(W_RESULT) TYPE  STRING
*"----------------------------------------------------------------------
data: w_len type i.
w_len = strlen( w_string ).

if w_len eq 7.
do.
  if w_string ca '-'.
    w_result = 'True'.
    replace '-' in w_string with space .
    if sy-index ge 2.
    w_result = 'False'.
    exit.
    endif.
  endif.
  check sy-index gt 2 .
  exit.
enddo.
else.
w_result = 'False'.
endif.
