Error while updating custom db table with internal table

Question

Hi experts,
My question is : I define a itable like
types begin of ty_data,
        f1(3)  type  c,
        f2(4)  type  c,
       end of ty_data.
data itab type standard table of  ty_data.
and my custom table(YDATA) is also same structure of  itab.
then  I use insert statement like this
loop at itab into wa_data.
  INSERT into YDATA values wa_data.
endloop.
my problem is I get  an error like this
The type of the database table and work area (or internal table)          
"wa_data" are not Unicode-convertible . . . . . . . . . .     
please give me the solution for this error.
Thanks

Please post ABAP-questions in one of the <a href="https://forums.sdn.sap.com/index.jspa#42">ABAP forums</a>.
My small addition to the existing hints: define the work area using LIKE LINE OF, the LIKE keyword is a very nice way of ensuring that data types match. You can reference input parameters, other locally defined variables and more.
DATA: t_ydata TYPE STANDARD TABLE OF ydata,
      l_ydata LIKE LINE OF t_ydata[].
