Need to compare strings for case sensitivity

[Former Member]

I need to compare 2 strings using a pattern and i need the compare to be case sensitive.

CP is not case sensitive

CA is case sensitive - but it wont search for my specific pattern - it will find strings where any of the charaters match. I need to match on the whole search string.

Example: searching all long text fields that contain pattern Rm167.

my results are returning rm167, RM167 and Rm167.

How do i find ONLY Rm167 ?

Please help,

Hi Julia,

The comparision string should be like this in case of CA only '<b>Rm</b>'

Thank you

so do insert the <b> in front of my letters and </b> after my letters

and still use the CA ?

also what does the <b> stand for - what does it mean?

thanks

i am testing using <b> and </b> == but still getting the same results.

i am still matching on 'rm167' and i only want to match on 'Rm167'

please help

Hi Julia,

It should be according to your requirement.

<b>CA:</b>

<f1> CA <f2>

is true if <f1> contains at least one character from <f2>. The comparison is case-sensitive. If the comparison is true, the system field SY-FDPOS contains the offset of the first character of <f1> that also occurs in <f2> . If it is false, SY-FDPOS contains the length of <f1>.

e.g:

'ABcde' CA 'Bd ' true = 1

'ABcde' CA 'bD ' false = 5

Hi,

Your comparison operator should be '=' and not '=='

Reward if useful!

Hi Julio,

the characters of pattern must be prededed by # to make it case-sensitive.

i.e. 'ABcde' CP '#b' results in false

Hi. You may want to try this. When using the CP operator, there are some escape characters which will help when processing strings. So here, in this example str3 will only be matched. If you want to make the comparison case sensitive, you should put a # sign in front of the specific letter in the liternal. IN this case you want to match all.

report zrich_0001.

data: str1 type string.
data: str2 type string.
data: str3 type string.


str1 = 'rm167'.
str2 = 'RM167'.
str3 = 'Rm167'.

if str1 cp '#R#m#1#6#7'.
 write:/ 'Str1 matched'.
endif.

if str2 cp '#R#m#1#6#7'.
 write:/ 'Str2 matched'.
endif.

if str3 cp '#R#m#1#6#7'.
 write:/ 'Str3 matched'.
endif.

Check the help on CP.

selection_option s_ltxt for TLINEs-tdline.

s_ltxt = ICP#R#m#1#6#7

t_first_print-zztline1 = rm167

if t_first_print-zztline1 in s_ltxt or

t_first_print-zztline2 in s_ltxt or

t_first_print-zztline3 in s_ltxt.

keep_notif = 'Y'.

endif.

my flag keep_notfi is being set to Y when it should not match on the little letters

[RichHeilman]

Did you APPEND to your select-option?

select-option s_ltxt for TLINEs-tdline.

s_ltxt = 'ICP#R#m#1#6#7'.
APPEND S_LTXT.

Yes - i did append.

and nothing has worked yet. I have tried all that have been posted here.

if anyone has an answer - even an ugly one - i will give it a try.

My user is VERY picky and I must provide this functionality.

Hi Julia,

OK I tried for you. It should make no difference so I did not use any # character in front of digits because there are no upper or lower case digits on this planet.

I got this output

Rm167                                    is matched by pattern #R#m167              
rm167                                    is not matched by pattern #R#m167          
RM167                                    is not matched by pattern #R#m167          
rM167                                    is not matched by pattern #R#m167          

using this code:

FORM ANY .
DATA:
  lr_text TYPE RANGE OF text40 with header line,
  lv_text1 type text40 value 'Rm167',
  lv_text2 type text40 value 'rm167',
  lv_text3 type text40 value 'RM167',
  lv_text4 type text40 value 'rM167'.
  lr_text-sign = 'I'.
  lr_text-option = 'CP'.
  lr_text-low = '#R#m167'.
  APPEND lr_text.

  IF lv_text1  IN lr_text.
    WRITE: / lv_text1, 'is matched by pattern', lr_text-low.
  ELSE.
    WRITE: / lv_text1, 'is not matched by pattern', lr_text-low.
  ENDIF.
  IF lv_text2  IN lr_text.
    WRITE: / lv_text2, 'is matched by pattern', lr_text-low.
  ELSE.
    WRITE: / lv_text2, 'is not matched by pattern', lr_text-low.
  ENDIF.
  IF lv_text3  IN lr_text.
    WRITE: / lv_text3, 'is matched by pattern', lr_text-low.
  ELSE.
    WRITE: / lv_text3, 'is not matched by pattern', lr_text-low.
  ENDIF.
  IF lv_text4  IN lr_text.
    WRITE: / lv_text4, 'is matched by pattern', lr_text-low.
  ELSE.
    WRITE: / lv_text4, 'is not matched by pattern', lr_text-low.
  ENDIF.

ENDFORM.                    " any

Hope this will help you to make your picky users happy again.
