I think this should be done as validation after input only. But, no matter what data you enter, since it will be compatible with String type, ti will not throw an error. You can do this validation for other data types maybe, but I doubt if it will work on a string.

Hi Kanti

You don't need a function module.

You can do this by using the following statement:

if var1 ca '0123456789'.

...

endif.

<b>CA</b> Contains Any: True, if operand1 contains at least one character from operand2. Upper/lower case and trailing blanks are taken into account for both operands. If operand1 or operand2 is of type string and initial, the logical expression is always false. If result of the comparison is positive, sy-fdpos contains the offset of the first character in operand1 that is also contained in operand2. If the result of the comparison is negative, sy-fdpos contains the length of operand1.
