settlement type should be FUL, when settling WBS element to PSG through automatic generation of settlement rule (CJB1/CJB2)

Hi Experts...

Manually I am able to make settlement type as FUL, when settling WBS element to PSG in the settlement rule, but the problem is with automatic settlement rule generation.

System is deriving settlement rule automatically through CJB2, but it is generating settlement type as PER, but the requirement is to have FUL.

Please help me out....

Thanks...
