Try out the ABAP Runtime Type Services (RTTS). This service lets you do all kinds of things dynamically at runtime. Refer to the class "cl_abap_structdescr"

For information and examples search the SDN on RTTS or RTTI.

Have you included a space in the string '0123456789 '?

Space is required in the checking string, because your field will have space apartform digits.

Thanks again you are right i missed the space one ..

but Now another problem...

I have tried that but in that case even user can input data by mistake like this

123 4 but this is not an integer it should also give error as this is also not a correct integer ...

as par asi think . we have to aain check if there is any spaces in the data provided i guess or

is there any other procedure ?
