Question about CO and CA operator

[Former Member]

Hi,

I have a field for which I want to detect a case where if it is null or contains any alphabhet from a to z.

For this I have defined a constant:

  CONSTANTS: c_valid(26) TYPE c VALUE
  'ABCDEFGHIJKLMNOPQRSTUVWXYZ'.

But I get confused in using CO and CA operator. How can I achieve above logic.

Thanks,

CD

You want to use CA(Contains Any) because you want to know if there are ANY alpha characters here, Contains Only would be if you wanted to test that it Only contains values other than alphas, in your case.

if lv_value is initial 
    or lv_value CA sy-abcde.

endif.

You can use SY-ABCDE instead of defining a constant.

IF field IS INITIAL OR field CA SY-ABCDE.

...

ENDIF.

CA = "contains any".

For detailed explanation of these operands, see ABAP online help for the IF-statement.

Hello,

Use CA operator.

data: w_valid(26) TYPE c VALUE

'ABCDEFGHIJKLMNOPQRSTUVWXYZ',

w_value type char10 value 'Jayant'.

if w_value CA w_valid.

message 'Welcome to SCN' type i.

endif.

Hope it helps.

Thanks,

Jayant
