Dump

HI All

  SELECT SINGLE ebeln lifnr aedat FROM ekko INTO (gv_request, gv_supplier, gv_creationdate)    "Purchase Order Number,Supplier,Create Date

                                               WHERE ebeln = gv_request_number AND

                                               verkf =  gv_customername AND

                                               telf1 =  gv_conactnumber OR

                                               ( aedat =  gv_fromdate OR aedat =  gv_todate ).

in Fm gv_request_number, gv_customername, gv_conactnumber are mandatory fields

When i excute i am getting dump with this query.

And i want wild card search for gv_customername, gv_conactnumber.

Thanks
