I have worked with @Nik on this, and his response was the following:
everything Ok, you have to know logic: rollover ONLY CAP-data, main trafic not rollover!
So on first screen: not used CAP 24.6 +20 (main data) = 44.6 as it is
second screen - 36.2 + 20 = 56.2
My response to that:
Hi Nik! Thanks for checking, however the logic does not make sense… In a capped environment we need to have main data to also rollover, as the client have paid for that data aswell… how can we make this work?
He then replied:
Hi goose, now it’s not working, but I sent it to our dev-team and I think they will fix it, so please wait
Thank you @Nik, I hope we can get this rollover working the way I think it should be working
Hi there, here is a description of how rollover should work :
Rollover expiration is set in Config -> CAP.
Let’s setup rollover expiration to 2 month. (personally I think better is to do 1 month to have it clear)
Customer has month CAP of 10 GB.
In January he used 5GB, and 1st of February remaining 5 GB are moved to his TOP UP data.
These 5 GB will expire 31st of March.
In real practice :
In January customer uses 5 GB, remaining 5 GB are moved to next 2 months.
in February customers uses 12 GB, he is allowed to do it, because he has 10 GB of regular CAP + TOP UP of rollover.
In March customer uses 10 GB. He was able to use 3 GB of TOP UP from rollover, but didn’t use it.
In April customer has 10 GB of his regular CAP (the TOP UP of rollover expired).
This is 2 months rollover scenario. As I wrote above, I think 1 months is better to manage/understand/explain to customers. Or other option is never expire.
