BOM Comparison & Management


If your company maintains both engineering bill of materials and manufacturing bill of materials, it could become difficult to manage the differences between the two and keep both up-to-date. Especially, when engineering changes are continuously being made. 


Proplanner's Assembly Planner makes this bill of material comparison and management easy. When a new eBOM or mBOM for any assembly is loaded into the system, Assembly Planner will highlight any discrepancies between the two bills of materials.


To learn more about BOM comparisons and how they are managed, please watch this quick 3-minute video. 

Additional BOM information:

Most clients have Assembly Planner import the eBOM from their PDM/PLM system along with a corresponding Engineering Change Order which contains important details about this change. Assembly Planner then allows the manufacturing engineer to reconcile the eBOM against any existing mBOM (if one exists) to determine what subsequent changes need to be performed against the Process and subsequent shop floor instructions, tooling, and logistics.

mBOM Authoring:

Reconcile the mBOM directly against the new eBOM and reconfigure to meet manufacturing requirements.

  • Generate a side-by-side comparison of the new eBOM and the current mBOM. 

  • View color-coded flags that highlight the differences between the BOMs. 

  • Automatically determine items that are new to the system or new to the BOM. 

  • Identify the last usage of an item to plan for inventory changeovers.

  • Set effectivity dates, adjust quantities, and split items across operation sequence numbers.
