Explain the outcome on the invoice for NOT specifying chargeID vs specifying charge ID in the usage?

[JeanChristophe]

We have a subscription which contains two rate plans.

Each rate plan (plan-A and plan-B) will have charge ID assigned

Usage included in the plan are different for each rate plan (e.g, 500 units at $0.50 vs. 1000 units at $0.10).
On the invoice usage section, we want to see plan-A usage billed and plan-B usage billed separately.

Could you explain the outcome on the invoice for NOT specifying charge ID vs specifying charge ID in the usage ?

(In the Usage we specify the account and subscription.)

1. If you do NOT specify Charge ID,  
   
   A Usage with 1100 UOM will be billed as below:
   • Rate plan Charge A -  500 free UOM, 600 UOM billed at $0.50 each = $300
   • Rate Plan Charge B - 1000 free UOM, 100 UOM billed at $0.10 each =  $10
     
     
2. If you do specify the Charge ID ( Rate Plan Charge A )
   
   The usage will be billed with each Rate Plan Charge A  provisionned to the Subscription
   • Rate plan Charge A -  500 free UOM, 600 UOM billed at $0.50 each = $300
