Check the Types as Follows.

>DATA:lr_descrref TYPE REF TO cl_abap_typedescr.

>lr_descrref = cl_abap_typedescr=>describe_by_data( variable ). " this is the variable of >which you want to check the type of

>CASE lr_descrref->type_kind.

>WHEN= 'P'.

> Packed Number

>WHEN 'C'.

> Character

>WHEN OTHERS.

> And so on.

>ENDCASE.

This would be the best way to check types dynamically.

Friend,

use the FM NUMERIC_CHECK

parameters: ch(10).

data: ty type DD01V-DATATYPE.

CALL FUNCTION 'NUMERIC_CHECK'

EXPORTING

STRING_IN = ch

IMPORTING

STRING_OUT = ch

HTYPE = ty.

case ty.

when 'NUMC'.

when 'CHAR'.

endcase.
