Validate serial patterns

[Former Member]

Hi all!

I have this issue..

I have to validate serial patters if each character is Alphanumeric and numeric, for example:

Format1 > AAAANNAAANAA

Format2 > AAANNANAANAA

Format3 > AAANNANAANA

Format4 > AAANNNAAANAA

Format5 > NNNNNNNN

Format6 > AANNNNAAANAA

Taking as a example for the first one "AAAANNAAANAA" if I receive the value "ABCD12EFG3HI" should be ok

BUT! if I receive "ABCDQ2EFG3HI" (the number 1 changed for a "Q" it shout send an error

I was cheking the regex [:digit:][:alnum:] but I was not success.

Can you help me please?

Best Regards

You say that the incoming serial no must be validated with all the patterns available ?

Yep, it must to be validated, for example, if I receive this serial: ABCD12EFG3HI I have to validate that the first four positions are alphanumeric, the sixth and seventh are numeric eighth ninth and tenth alphanumeric, and so on, based on this pattern "AAAANNAAANAA"

I am sure there would be more elegant way, but you can try like this:

DATA: lv_pattern TYPE char20.
DATA: lv_value TYPE char20.
lv_pattern = 'AAAANNAAANAA'.
lv_value   = 'ABCD12EFG3HI'.

DATA: lv_len TYPE i.
lv_len = STRLEN( lv_pattern ).
DATA: lv_char TYPE char1.
DATA: lv_val_char TYPE char1.
DATA: lv_index TYPE i.
DATA: mlen TYPE i.
DATA: lv_regex TYPE string.
DATA: lv_failed TYPE flag.
DO lv_len TIMES.
  lv_char = lv_pattern+lv_index(1).
  lv_val_char = lv_value+lv_index(1).
  IF lv_char = 'A'.
    lv_regex = '[a-zA-Z]'.
  ELSEIF lv_char = 'N'.
    lv_regex = '[0-9]'.
  ENDIF.
  lv_index = lv_index + 1.
  FIND REGEX lv_regex IN lv_val_char
   MATCH LENGTH mlen.
  IF sy-subrc NE 0.
    WRITE: 'Error at position', lv_index,
           'expecting', lv_regex, 'but found otherwise'.
    lv_failed = 'X'.
    EXIT.
  ENDIF.
ENDDO.
IF lv_failed IS INITIAL.
  WRITE: 'Looks good'.
ENDIF.
