User Story

As a CHED-PP Trader using the API
I Want to Provide a Total Gross Weight
So That IPAFFS knows the Total Gross Weight of my consignment

**Acceptance Criteria**

Scenario 1 - Total Gross weight is more than Total Net Weight
Given I'm creating a CHED-PP notification through the API
When a Total Gross Weight is provided
And the Total Gross Weight is higher than the Total Net Weight
Then the data is added to the IPAFFS notification

**Scenario 2 - Error When Total Gross weight is Less than Total Net Weight**
Given I'm creating a CHED-PP notification through the API
When a Total Gross Weight is provided
And the Total Gross Weight is less than the Total Net Weight
Then an error event is created
And the data is not added to the IPAFFS notification
