What values pull into a variation BOQ from a change event?
When creating a new variation from a change event or linking a change event line item to an existing variation, the bill of quantities (BOQ) in the variation will populate with a value from the change event line item source. This article summarises how the value is determined within the change event line item so you will know which values will carry over into the variation.
When creating or linking a commitment variation or potential variation, the Latest Cost amount for each selected change event line item will carry over into the variation BOQ.
If a potential variation or main contract variation is linked to the change event before linking a commitment variation, the Latest Price amount will override the latest cost and pull through to the commitment variation BOQ.
If this happens, you can edit the value for the BOQ line item on the variation after it is created/linked.
Main Contract Variation
When creating or linking a main potential variation or main contract variation, the Latest Price amount for each selected change event line item will carry over into the variation BOQ.
How are the Latest Price and Latest Cost Values Determined?
The latest price is determined by the most up-to-date value in the revenue portion of the change event line item columns. This includes the ROM and Main/Prime PV columns. The Revenue ROM value is used to determine the initial latest price value. Once a 'Main/Prime PV' value has been added, the latest price will update to match the 'Main/Prime PV' column.
It is possible to have the 'Revenue ROM' value match the latest cost. See How Change Event Scope Impacts Revenue ROM below.
The latest cost is determined by the most up-to-date value in the cost portion of the change event line item columns. This includes the ROM, RFQ, and Commitment columns. The cost ROM determines the initial value of the latest cost. After that, an RFQ value and finally a commitment value is used to set the latest cost on a change event line item.
