Copy plan and actual data in KP97 and KP98

Hi,

I have a requirement where I have to copy Plan cost in KP97 from one version to another. I get all the data except Planned cost. The same is required in KP98.

I have to get plan cost from KP06.

Can anyone tell me any BADI which can allow me to create one additional column on KP97 and KP98.

Also, in which database table, value from KP06 are stored?
