how can i compare the character fields?

[Former Member]

I have a requirement to compare the character fields .

I have to compare the 2 character fields of a table CDPOS

As follows .

If CDPOS-VALUE-OLD GT CDPOS-VALUE-NEW

Populate REDATED = ‘YES’.

ELSE

Populate REDATED = ‘NO’.

My doubt here is how can we compare the character fields.?

When I do Extended Program Check: I am getting error like this ?

Greater than/less than comparisons with character type operands may not be portable

Please give me idea .

Thanks ,

DATA: SC1(16) TYPE X,

SC2(16) TYPE X.

CONVERT TEXT CDPOS-VALUE-OLD INTO SORTABLE CODE sc1.

CONVERT TEXT CDPOS-VALUE-NEW INTO SORTABLE CODE sc2.

IF SC1 GT SC2.

ENDIF.

Hi suresh,

DATA : a TYPE char10  VALUE 'DBCD',
       b TYPE char10  VALUE '4234',
       c TYPE char10  VALUE '3456',
       d TYPE char10  VALUE 'ADA',
       e TYPE char10 VALUE  '234567'.

IF b GT c.        "this case checks for numeric values
  WRITE 😕 'B is bigger'.
ELSE.
  WRITE 😕 'C is bigger'.
ENDIF.

IF a GT d.      "this case checks for alphbetical order
  WRITE 😕 'A is bigger'.
ELSE.
  WRITE 😕 'D is bigger'.
ENDIF.

IF strlen( a ) GT strlen( d ). "this case checks for no of chars
  WRITE 😕 'A is bigger'.
ELSE.
  WRITE 😕 'D is bigger'.
ENDIF.

IF a GT c.      "this case first alph then numerics
  WRITE 😕 'A is bigger'.
ELSE.
  WRITE 😕 'D is bigger'.
ENDIF.
