Double click on table control

Hi Experts,

I am having a table control.In that there is a field called Production Order.When I am double clicking on that field it is taking me to the transaction CO03.

But the problem is it is going to the transaction CO03 without the value of production order.The piece of code which i am using is given below.

WHEN 'CO03'.

DATA : fname(40),

fvalue(40).

CLEAR :fname,

fvalue.

GET CURSOR FIELD fname value fvalue.

IF fname = 'WA_OVERVIEW-AUFNR'.

CALL TRANSACTION 'CO03'and skip first screen.

ENDIF.

Please help me out hoe to get the value of the production order in the CO03 transaction.Help will be appreciated.

Regards

Sourabh
