The Renewal block

This part is easy.  Set the renewal % to 100 and the cancel % to whatever percentage cancel the renewal.  Set the cancel flow in the normal way. 

If some subscribers cancel before the renewal term starts go into Options/Options and on the Subs tab check the box that says Allow 0 Iss Bef Canc.  Then set the Mos Bef Canc (or Iss Bef Canc) to 0 and start the flow from there.

The Expires block

The problem here is that if you renew everyone a few months before expire, as is normal, the original expire group is now 0 and the model doesn't know how many there were originally so it can't unscramble that expire group to model the cancel flow.

The solution is to re-enter by hand the original expire count for those expire groups that have been renewed but will still have cancels after the expire upload is pulled.  Do not change the future expire groups, leave them as they were uploaded.

This works because the unscrambling process does nothing with the old expire group because it knows that 100% have already renewed.  It doesn't generate future expires or change subs served counts.  When processing renewals it knows that that group has renewed before the expire upload was pulled but it does calculate the cancels from the renewed group.

This works on both versions 5.0 and 4.8.
