Rollover:
Selection of Conditions to be Transferred 
Use
When you use the automatic rollover function, the system no longer transfers conditions that are based on a disbursement commitment if no disbursement commitment exists on the rollover date.
This was already the case for the individual rollover function. However, up to Release 4.6C the system transferred these conditions (such as commitment interest) when an offer was created using the automatic rollover function, even if the contract was fully disbursed.
From Release 4.6C, such conditions are not transferred to the new fixed period, regardless of whether you use the individual rollover or automatic rollover (mass processing) function.
