Hi,

C, N, D, T, X data types are the member of character faimily.

so the way u do with character c, the same method we use for numeric field.

data: a type i,

TP_RLNUM(16) TYPE N

a = strlen( TP_RLNUM ),

IF A = 16.

TP_RLNUM(16) itself means that it cant take more than 16.

why coding?

Sorry somewhat my last mail was posted and it was incomplete.

*****write ur logic here******.

endif.

Hope this will help u.

Hi,

Variables of type n lenght 16 will always have 16 characters :

e.g. if value = 7

variable = '0000000000000007'.

Hi,

You can also do this using RTTS (Run Time Type Services).

DATA: tp_rlnum(16) TYPE n.   "your data object

DATA: r_eldescr TYPE REF TO cl_abap_elemdescr.   

r_eldescr ?= cl_abap_typedescr=>describe_by_data( tp_rlnum ).  "get element's attributes

WRITE: 'Output length of the data object is', r_eldescr->output_length.  "display its length

This approach give you opportunity to check every single attribute of your data object. I.e. now you can see its type as well:

write: 'Type is:', r_eldescr->type_kind.

PARAMETERS p_num(16) TYPE n.

AT SELECTION-SCREEN.
  DATA: out TYPE char16,
        len TYPE i.
  out = p_num.
  SHIFT out LEFT DELETING LEADING '0'.
  len  = STRLEN( out ).
  IF len  NE 16.
  ENDIF.

Hi,

To check the length by strlen( TP_RLNUM ) alwys giv u 16 becz ur data type itself says that.

Rather then that check the first character of ur no that should not be 0 it means that ur no is always 16 digits.

data: a type i.

a= TP_RLNUM + 0(1).

if a <> 0.

write ur logic here.

endif

Thanks ,
