How to validate when date format is diff Internally and externally

Question

Hello,
How can I validate the Date format if Internal format and external format is different.
Ex :
*  SELECT SINGLE CRTSP
**                FROM /SAPSLL/PR
**                INTO L_CRTSP
**                WHERE CRTSP IN S_CRTSP .
CRTSP (YYYY/DD/MM HHMMSEC) Internal Format
S_CRTSP (YYYY/DD/MM) External format - selection option
I had done following to convert the internal format to external format.
DATA : LV_DT TYPE STRING.
DATA :  L_CRTSP TYPE /SAPSLL/CRTSP.
SELECT SINGLE CRTSP
                FROM /SAPSLL/PR
                INTO L_CRTSP.
MOVE : L_CRTSP TO LV_DT. "(YYYY/DD/MM HHMMSEC)
L_LEN = STRLEN( LV_DT ).
L_DATE = LV_DT+0(8).
I have the date format that i need in L_DATE."  (YYYY/DD/MM)
Now how should I validate?
*  SELECT SINGLE CRTSP
**                FROM /SAPSLL/PR
**                INTO L_CRTSP
**                WHERE CRTSP IN S_CRTSP .
Please let me know how can I validate or how can I write the select query to validate this field.
There should be some way using Wildcard or some function module...which I am not sure...
Any suggestions will be appreciated!

Answer 1

Hello,
Thank you for youe response and I apprecaite the help so far.
This logic work if it is Parameter...When I have select option it is not working as it is not taking the range values...
SELECT GUID_PR "Primary Key as GUID in "RAW" Format
CRTSP "PRODUCT CREATED ON
CHTSP "PRODUCT CHANGED ON
FROM /SAPSLL/PR
INTO TABLE T_PR.
DATA : T_PR1 TYPE TY_PR OCCURS 0 WITH HEADER LINE.
DATA:  W_TEST    TYPE STRING,
       W_LV_LEN  TYPE I,
       W_LV_LEN1 TYPE I,
       W_LV_DATE(20)  TYPE C,
       W_LV_DATE1(20) TYPE C.
DATA : W_V(8) TYPE C,
       S_CT(11) TYPE C.
SORT T_PR BY CRTSP CHTSP.
LOOP AT T_PR INTO WA_PR.
  W_TEST = WA_PR-CRTSP.
  W_LV_LEN = STRLEN( W_TEST ).
  W_LV_DATE = W_TEST+0(8).
** IF WE SELECT ONLY ONE DATE IN SELECT OPTION
s_crtsp VALUE IS - IEQ20040101..bY REMOVING FIRST THRID DIGITS
WE ARE GETTING THE S_CRTSP VALUE IS 20040101 AND THIS LOGIC IS WORKING FINE..
   MOVE S_CRTSP TO S_CT.
  W_LV_LEN1 = STRLEN( S_CT ).
  W_LV_DATE1 = S_CT+3(8).
*  IF W_LV_DATE NE S_CRTSP
IF W_LV_DATE NE W_LV_DATE1.
  W_FLG = 'X'.
    DELETE T_PR INDEX SY-TABIX.
  ENDIF.
  CLEAR W_FLG.
ENDLOOP.
Can we do anything for this...
ANy suggestions would be apprecaited!
