Savings overdraft fee with charge time type 'overdraft fee' and charge calculation '%amount' is not working

1. Go to charges and select charge applied to 'Savings and deposits'
2. Fill other required inputs with
Charge Time type: overdraft fee
Charge calculation : % amount.
Amount : 1
> After submission , it is throwing error: "validation.msg.charges.charge.calculation.type.percentage.allowed.only.for.withdrawal.or.noactivity"

Expected:
1.This feature of overdraft fee with charge calculation as % amount need to be implemented.

2. Until the feature is implemented, the following proper error message should be thrown in stead of above mentioned:
""validation.msg: charge.calculation.type.percentage.allowed.only.for.withdrawal.or.noactivityand yet to be implemented for overdraft fee"
