PackageOfMeasures - Add UserDefinedFields

Overview

PackageOfMeasures does not have UserDefinedFields.

Justification

There exists a need for certain users to add user-defined fields on PackageOfMeasures

Implementation

This proposal is to:

Add the following elements under BuildingSync/Facilities/Facility/Reports/Report/Scenarios/Scenario/ScenarioType/PackageOfMeasures:

1. UserDefinedFields
2. UserDefinedFields/UserDefinedField
3. UserDefinedFields/UserDefinedField/FieldName
4. UserDefinedFields/UserDefinedField/FieldValue
