An attempt to change the option "Charge for subscription" or "Billing Period" in the service plan delegated to the reseller(s) results in the error:
This Plan has been delegated to Resellers. You are not allowed to modify Recurring Type. This Plan has been delegated to Resellers. You are not allowed to modify Billing Period Type.
It is not possible to change an option for the delegated plans, there is a request to allow it - #PBA-13939 ("Change option 'Charge for Subscription' for delegated plan").
It is correct system behavior that billing period shall not be changed for the plans that are delegated to the reseller. The restriction is explained by the fact that the reseller is billed by the settings that are defined in the provider's service plan, which means the changes in billing for the reseller are made "on a fly" - as soon as the change on the providers plan is done (if it had been possible), so the reseller would be billed some price for 1 month, while all the resellers customer would be billed the same price for a year. Moreover, possibility of option change can cause unexpected billing of the existing subscriptions".
