Review missing-in-source PMI information
Product manufacturing information (PMI) may appear missing in the manufacturing bill of materials (MBOM) due to a design change, or because it is connected to, or referenced by, another external assembly. From a single location, you can review a list of PMI objects that are assigned to a process or operation, in the same way you can review parts that are missing in the source engineering bill of materials (EBOM).
Procedure
If you have not done so already, search for and open an existing work package that contains processes and parts and navigate to the Work Instructions Authoring page.
Click the Process tab and enable Show Comparison.
To the right of Show Comparison, the number of parts that are overconsumed in the loaded process are reported. The next field shows the number of parts and PMI objects that are missing in the source for the loaded process.
The Process tab displays a red indicator . Below the tab, a Missing In Source list details the dimensions, feature control frames, and geometric dimensioning and tolerancing (GD&T) elements that are missing from the work package source. The number of elements missing from the source appears to the right of each kind of element.
- On the Process tab, click a process or operation to which PMI information is assigned, and then click the PMI Assembly Level tab.
The PMI Assembly Level tab displays a red indicator and affected PMI elements display missing-in-source icons . The PMI tab in the information panel below the PMI Assembly Level tab displays the same icon for all PMI elements missing in the source from the selected process or operation.
When the parts are reclaimed, the warnings are resolved.
