Specifying partial match criteria for enterprise BOP structures

In addition to comparing properties, when you compare processes, operations, and partitions in enterprise BOP structures, Teamcenter can check the following criteria:

• Product assignment Teamcenter applies product assignment match criteria only to process and operation lines. It compares:

Logical assignment definitions Teamcenter identifies a match if, for each logical assignment of the first process or operation, it finds a distinct logical assignment of the second process or operation. That is, both logical assignments contain the same definition for the product logical designator they use. This assessment can take into account if the compared logical assignments are resolved or if the resolved assignments match.

Manual product assignments The identification of a product assignment is based on occurrence type and a match is identified if, for each line under the source process or operation, a distinct equivalent line is found under the target process or operation. They are equivalent if both lines have the same occurrence type and the same absolute occurrence. The product assignment of the matching processes or operations are checked and must completely match to qualify as a full match. If the product assignments do not match, Teamcenter identifies a partial match. Note For product assignment lines to match by either of the criteria described, they must be assigned from a structure and not from a library or other resource. Consequently, even if the BOP structure uses product items that are not represented in the BOM structure, you must collect them into another structure (for example, the MBOM) before assigning them. If you assign them directly to the BOP as items, the processes or operations to which they are assigned will never qualify for a full match by product assignment.

If one structure's process or operation has more assignments of a particular product than the other, this also qualifies as a partial match. Packed lines are taken into account when determining if the same number of product instances is present.

• Resource (tool) assignment Teamcenter applies resource or tool assignment match criteria only to process and operation lines. It identifies a resource mismatch by comparing the immediate children of equivalent processes or operations and their respective resource assignments. A resource assignment is identified by its specific occurrence type. It identifies a match if, for each resource assignment under the first process or operation, it finds an equivalent resource assignment under the second process or operation. It determines equivalence according to the item ID of the assigned resource. As the item ID is the same for different revisions of the same resource, different revisions are considered equivalent and do not cause the resource assignment to qualify as a partial match. All resource assignments of the equivalent processes or operations must completely match or the processes or operations are considered as a partial match. If the processes or operations have different quantities of a particular resource, it is considered as a partial match. Packed lines are taken into account when determining if the same number of resource assignments is present. However, a difference in the order of the resource assignments does not constitute a mismatch.

• Parent partitions Teamcenter applies parent partition match criteria to lines directly under partitions. In generic BOPs and product BOPs, these are partition lines and process lines. It identifies a match if the compared lines have equivalent partitions as parents, based on the internal partition ID, origin link, or logical designator.

• Predecessors Teamcenter uses predecessors to determine the flow in the PERT chart. Equivalent lines that have different predecessors qualify as a partial match. Teamcenter can optionally compare structure-specific operations. When structure-specific operations are not included in the comparison, Teamcenter checks if an operation is structure-specific. If it is, Teamcenter compares with the operation’s predecessor.

• Descendants Equivalent lines that have different child operations or processes qualify as a mismatch.
