its better if you use an if condition

<code>.

<code>.

endif.

Generally, it is BAD to use offsets if you can avoid it. So while the above will work, they are not good practice. Good practice would be:

IF this CP 'XX*'.

Note, however, that with CP, upper/lower case is disregarded. If you need to consider case use

DATA: moff TYPE i.
FIND 'XX' IN this RESPECTING CASE MATCH OFFSET moff.
IF sy-subrc IS NOT INITIAL or moff GT 0.
  WRITE: / 'Fail'.
ELSE.
  WRITE: / 'Sucess'.
ENDIF.

Or, if you want to be super cool.


FIND REGEX '^XX.*' IN this.
IF sy-subrc IS NOT INITIAL.
  WRITE: / 'Fail'.
ELSE.
  WRITE: / 'Sucess'.
ENDIF.

OK - never mind. I see you chose to follow bad practice.

hi,

you can use *(star), +(plus),#(hash) along with CP(contain pattern).

plz see below details also.

The CP (contains pattern) and NP (no pattern) operators perform a string search that allows pattern-matching characters. The expression v1 CP v2 is true when v1 contains a sting that matches the pattern in v2. The expression v1 NP v2 is true when v1 does not contain a string that matches the pattern in v2. The pattern matching characters allowed in v2 are given below.

Character Used to

*(STAR) Match any sequence of characters

+(PLUS) Match any single character

#(HASH) Interpret the next character literally

#is the escape character. A single character following it is interpreted exactly. Special meaning, if it exists, is lost. You can also use # to make a search case sensitive or to search for the *, +, or # character. Below table shows examples of how you might use these characters. The escape character is needed when you want to perform a case-sensitive search using CS, NS, CP, or NP. You also need it if you want to perform a pattern search (CP or NP) for a string containing *, +, or #.

Statement True When

v1 CP ‘A+C’(A plus C) v1 contains “a” in the first position and “c” in the third. Either character can be in upper- or lowercase. Any

character can appear in the second position

v1 CP ‘Ab’(star AB star) The string can appear anywhere within v1. Either character can be in upper- or lowercase.

v1 CP ‘#A#b’( star hash A hash B star) v1 contains a capital A followed by lowercase b

v1 CP ‘##’( star hash hash star) v1 contains a #

i think this is useful for u,

*reward me if it is useful to u.*
