How to populate values of field symbols?

HI,

I need to pass values into a field-symbol (defined as a dynamic Work Area) and append the values later on into another field-symbol (defined as a dynamic Table) by inserting the work area to the table. The insert statement in the screen shot below is syntetically correct but when I uncomment

• *      <gw_itab>-tplnr = 'TPLNR'.
• *      <gw_itab>-pmsog = 'PMSOG'.
• *      <gw_itab>-k_pro = 'K_PRO'.

I get a syntax error. During debugging if I pass the values of the work area, they are properly appended into the table.

Could somebody show me the code on how to atain this programatically?

Thanks for your help

Carl
