hello madhu,
i have got the sollution. in the webservice i'm giving the input (03D86AFB7EE7D14585EF515C59B5F559) same as in data base .while testing the webservice  internally the value should be converted into bytes bcoz  in the domain  the data type was RAW .
so db didnt recognise that value thats why i got the error.
so i use the fm  GUID_CONVERT and convert that as db format
thanks for ur response .
regards,
sashi.
