Hi Gurus,

I have a problem with the REPLACE command.

lets say I need to replace 'ITAB' with 'I_ITAB'.

But actually its also replacing in 'ITAB1' also coz it contains 'ITAB' in it.

I tried using LENGTH option in the REPLACE command .But it didnt work out.

Please help .

Hi ,

You need to use REPLACE thrice .

First you need to replace ITAB1 with the most unused string (in the below EX: 'XYZ').

Now replace ITAB to I_ITAB.

Now repace back 'XYZ' to ITAB1.

Check bellow code - -

DATA : w_string TYPE string VALUE 'ITAB ITAB1'.
REPLACE 'ITAB1' IN w_string WITH 'XYZ'. " replacing ITAB1 to XYZ
REPLACE 'ITAB' IN w_string WITH 'I_ITAB'. " Replacing ITAB to I_ITAB
REPLACE 'XYZ' IN w_string WITH 'ITAB1'.  " Replacing back XYZ to ITAB1
WRITE : w_string.

If you want replace all the occurrences try this - -

DATA : w_string TYPE string VALUE 'ITAB ITAB1'.
REPLACE ALL OCCURRENCES OF 'ITAB1' IN w_string WITH 'XYZ'.
.
.

Hi,

If for eg variable contains 'ITAB ITAB1'.

Replace first occurence of 'ITAB' in <variable name> with <new value>.

U can also use offset value and length to replace a specific area in a string.

Replace 'ITAB' in SECTION [OFFSET off] [LENGTH len]

with <new value>.

specify offset anf lenght which defines the section for which the replacement ll take place.

ajit.

example:

LOOP AT it_otfdata1 INTO wotfdata .

REPLACE ALL OCCURRENCE OF 'DUPLICATE' IN wotfdata-tdprintpar WITH 'ORIGINAL'.

IF sy-subrc = 0.

MODIFY it_otfdata1 FROM wotfdata INDEX sy-tabix TRANSPORTING tdprintpar.

ENDIF.

ENDLOOP.

Hi,

Please go through this code. This will solve your issue.

DATA: fir TYPE i,

sec TYPE i,

result_tab TYPE match_result_tab,

res TYPE LINE OF match_result_tab,

BEGIN OF tab OCCURS 0,

line(255),

END OF tab.

tab-line = 'this is ITAB line'.

APPEND tab.

CLEAR tab-line.

tab-line = 'this is ITAB1 line'.

APPEND tab.

CLEAR tab-line.

tab-line = 'this is ITAB line'.

APPEND tab.

CLEAR tab-line.

tab-line = 'this is ITAB1 line'.

APPEND tab.

CLEAR tab-line.

LOOP AT tab.

FIND ALL OCCURRENCES OF 'ITAB' IN

tab-line

RESULTS result_tab.

LOOP AT result_tab INTO res.

fir = res-offset - 1.

sec = res-offset + res-length.

IF tab-linefir(1) = space AND tab-linesec(1) = space.

REPLACE ALL OCCURRENCES OF 'ITAB' IN tab-line WITH 'I_ITAB'

REPLACEMENT OFFSET res-offset REPLACEMENT LENGTH res-length.

ENDIF.

ENDLOOP.

MODIFY tab TRANSPORTING line.

ENDLOOP.

LOOP AT tab.

WRITE : / tab-line.

ENDLOOP.

Hope this will help you.

Hi Kamala ,

As because you will be replacing some contents of a program , from a program ,

inside the loop you need to replace from the field string as I told last post.

LOOP AT internal_table TO field_string.
REPLACE ALL OCCURRENCES OF 'ITAB1' IN fieldng WITH 'XYZ100'. " replacing ITAB1 to XYZ100
REPLACE ALL OCCURRENCES OF 'ITAB' IN fieldng WITH 'I_ITAB'. " Replacing ITAB to I_ITAB
REPLACE ALL OCCURRENCES OF 'XYZ100' IN fieldng WITH 'ITAB1'.  " Replace back XYZ100 to ITAB1
ENDLOOP.

Definitely it will resolve the issue.

Hi Bharathi,

Why we need to use Loop inside a loop because we are not sure how many occurences will be there

for the searching string in a line.

If you are sure that only one occurance will be there, then instead of looping through RESULT_TAB we can have a read on RESULT_TAB with INDEX 1.

Mean while let me check any other possibilities.
