Change the sequence of mass maturity states for rollup calculations

A rollup calculation selects the mass value based on the maturity assigned to the weight type. For each BOM line, the mass value from the weight type with the highest maturity is used for mass rollup calculations.

By default, a certain sequence of mass maturity states is set for rollup calculations. However, if you want to change this sequence, set the maturity for different weight types in the WNB0_MassMaturitySequence preference.

In the preference, list the weight types in descending order of maturity you want to assign. The one at the top of the list is assigned the highest maturity.

In the following example, the highest maturity is assigned to the Actual mass, and the lowest maturity is assigned to the Budgeted mass.

The following table shows some parts with different mass values. The maturity is assigned as described in the WNB0_MassMaturitySequence preference example. Based on the maturity assigned to the weight types, the mass values marked with a checkmark (✔) are considered for calculating the rollup.

Part Actual (maturity 1) Asserted (maturity 2) Evaluated (maturity 3) Budgeted (maturity 4)
Engine 221 ✔ 225 229 223
Chassis - 421 ✔ 429 423
Wheel Assembly - - 29 ✔ 29
