    Hi Giri,

    Size on Disk will be equal to sum of sizes of all 50 fields.

    eg: Character field has One byte memory. So if u have a field of CHAR10 it will accupy 10bytes.

    For knowing load on CPU u can get in touch with ur BASIS team. They will take care of these things so that system will not crash even in peak load.

    Thanks,

    Vinod.

    hi i am not sure about the exact answer .....but we can find the field length in the bytes..like this.

    report ztest.

    tables:mara .

    DATA: text TYPE c LENGTH 1,

    blen TYPE i,

    clen TYPE i,

    bytes TYPE i.

    DESCRIBE FIELD text: LENGTH blen IN BYTE MODE,

    LENGTH clen IN CHARACTER MODE.

    bytes = blen / clen.
