ODBC 720 error

I have an app that worked previously and now started generating odbc 720 errors on the update row command. Any idea what is going on? Id’s rights have not changed

code …

result.AddRow

’ Print “18”

Call result.SetValue(“N_INPUT_LOG_ID”,n_input_log_ID)

Call result.SetValue(“C_INPUT_ID”,c_input_ID)

Call result.SetValue (“C_INPUT_LOG_STAT” ,c_input_log_stat)

Call result.SetValue (“C_RCD_DEL”,c_rcd_del)

’ Print “19”

result.UpdateRow

When ever I step through the code the result.Update row command generates the error. If I go into DB2, the row has been inserted and the data is there.

Why is the 720 error occuring and what aare the consequences in ignoring it?

Thanks
