Problem with fieldsymbol

Hi Experts,

     Can anybody help me. my requirement is ,

i have one internal table with fields,  WERKS , Y_FRM_DATE , STG_LOC_UTL

                                                      0001            20.05.2015     75%

                                                      0001            21.05.2015     90%

                                                     0001            22.05.2015     75%

                                                      0001            23.05.2015     90%

i have another  Dynamic internal table . this will increase or decrease based on date fields. Here selection screen date input fields will display as columns in Report. So requirement is , i want to move the normal internal table STG_LOC_UTL value to Dynamic internal table under date column.

it_itab ===>  <it_dyntab>     (field symbol)  ....and field catalog internal table is it_fcat1 .

dynamic internal table structure is ,   sf1     sf2    sf3     sf4    sf5     sf6  d1    d2     d3     d4     d5......dn

can anybody suggest me how to move data from internal table to filedsymbol.
