The BOM Compare identifies changes in parts and part properties between the 2 designs. Note that NetBom considers the value of the selected BOM_IGNORE property described in the Configuration Variables to determine is a part is actually populated. A part can exist in the Part List, but it will not be populated if the selected BOM_IGNORE property is True.
A sample report can be viewed here: bom1_diff_bom2.txt
The reports summarize the following Differences between the 2 design Part Lists:
- Part Number Qty Changes
- Reference Designator Part Number Changes
- Deleted Reference Designators
- Added Reference Designators
- Changed Reference Designators
- Part Number Change Summary
- Property Difference Report
- Lab Rework Instructions(LRI) Report
Part Number Qty Changes
Summarizes the change in Quantity between the 2 PartLists (BOMS) per Part Number.

Reference Designator Part Number Changes
This report summarizes the Reference Designator Differences between Design1 and Design2. This could arise from one of the following conditions:
- RefDes is populated in Design 1 but not in Design2
- This includes the effect of the selected BOM_IGNORE property
- Line 8 below reports that C13 is in both designs, but the BOM_IGNORE property is TRUE in Design2
- R41 exists in Design1 but did not exist in Design2
- This includes the effect of the selected BOM_IGNORE property
- RefDes is not populated in Design 1 but is populated in Design2
- This takes into account the state of the selected BOM_IGNORE properties in both designs
- C84 is in both designs, but the BOM_IGNORE property is True in Design1 and False (or does not exist) in Design2
- This takes into account the state of the selected BOM_IGNORE properties in both designs
- RefDes has a different Part Number in Design1 than it had in Design2
- Line 19 below reports that PCB1 has a different part number in the 2 designs

Property Difference Report
This report highlights any parts that have the same Part Number in the 2 designs, but where a Key Part Property (selected from the KEY_PROP_LIST config variable as described in Configuration Variables was detected to be different in the two designs. NetBOM will detect if they properties changed for every instance (ALL_INSTANCES) of the part or will detail the affected Reference Designators if only some of the parts had property mismatches.
