Product Costing CK11N

Hi Friends ,

All i need is an enhancement spot for Price ..

My requirement is  in TCODE CK11N  that is to ADD earlier cost component price ( IN) to the component price of next component ( OUT )

Val.Type (OUT ) price = Val.Type (INT ) + its cost price ...

Clik here to view.

I want is in place of amount 500 , i need amount from IN + 500 = OUT

Thank you ,

Bharathi
