How to default asset key's value in accounting segment values using SLA version R12.0.6

Hi,

We have asset key KFF with structure of segment1,segment2 and segment3 and accounting flexfield is having 8 segment structure. Now the requirement is to populate asset key's segment2's value to the accounting segment's segment6. And both the segments are having same values in the value sets . How to implement this thing in SLA? So that whenever we run create accounting program accounting flexfield's segment6 should be equal to the asset key's segment2 value.

Thanks,
