Prevent double accounting while rolling up structures with partitions
A structure element can belong to more than one partition within a partition scheme. In this case, when users try to perform mass rollup calculation, that element is considered more than one time. To prevent this double accounting, you, as an administrator, must set the value of the Ptn0IsMultipleBomlineMembershipAllowedInScheme business object constant to false in Business Modeler IDE (BMIDE). This business object constant is available with the Ptn0PartitionScheme business object. The default value of this business object constant is True. Setting the value of this business object constant to False ensures that an element is added only to a single partition within a scheme.
If a user has already added an element to more than one partition, and then you set the value of the business object constant to False, the user must manually unassign the element from the other partitions, so that double accounting does not happen.
