Why error "it should be a number" when "specific months" select as the period in product selector?

You are trying to change the period for a selected charge to "specific months" and get following error: "it should be a number".

The reason is because if the Billing Period is defined as Specific Months, you need to define the Specific Billing Period as well.

Please add the Field Specific Billing Period to the Field Set: Display Charge Fields in the Object: QuoteRatePlanCharge.

Setup -> Create -> Objects -> Quote Rate Plan Charge -> Field Sets -> Display Charge Fields -> Click Edit and add Specific Billing Period to the list as below.

Now you can add Specific Billing Period, if the Billing Period is changed to Specific Months in prod...
