Task Flow and Alignment Setup

Task flow to align design and engineering BOM

For a visual BOM experience, you align the design and the engineering BOM (Usage BOM or Assembly BOM). These can be aligned manually or automatically. As a product comprises numerous parts, the manual alignment process is complicated, error-prone, and time-consuming. To reduce this complexity, the alignment process can be automated. If a design structure already exists in Teamcenter, you can generate the corresponding engineering BOM. In the generated engineering BOM, the part occurrences are already aligned with the design occurrences. Similarly, if an engineering BOM already exists in Teamcenter, you can generate the corresponding design structure. In the design structure that is generated, the design occurrences are already aligned with the part occurrences.

In a usage BOM environment, you can also generate an Usage BOM from a design structure. The Usage BOM is linked to the design structure.

After the design structure, engineering BOM is generated along with the alignment, validate if the generated designs, BOM and alignments are correct. During validation, if you find that an alignment is incorrect, you first unalign the design occurrence and the part occurrence, and then align them again manually. During validation, you may also find that some design occurrences and part occurrences are not aligned at all. In this case as well, you perform the alignment manually.

Incorrect BOM generation and alignment can also be due to incorrect design or engineering BOM data. In this case, you must update the design structure or engineering BOM data accordingly. After the update, you must analyze the impact of the change on the corresponding BOM.

Once you validate that the engineering BOM data and the alignment data are correct, you release the engineering BOM to the manufacturing stage. Here, the engineering BOM is used for creating the manufacturing BOM to author the make or buy decisions.
