Comparing BOMs
1. From the Actions menu, click Compare.
2. Click Product to access the Find: Product window, where you can enter various search criteria.
Product Name—Enter a complete or partial product name. This field also accepts wild-card searches.
Created and Last Updated—Enter a (From / Equals) and (To) date. Alternatively, you can also enter a date in only the (From / Equals) field, and then click Equals. The system automatically enters the same date in the (To) field.
Lifecycle State—You can double-click the life cycle states you want to search on, or you can select the life cycle state and click Add. Selected life cycle states appear on the right, in the Chosen box. To remove a life cycle state, you can either double-click it, or you can select it and click Remove.
* 
Press CTRL to select multiple life cycle states, and SHIFT to select a range.
Selecting a product type from the Product hierarchy brings up additional search criteria that are available for that product type. You can enter search values, or you can select and remove these search criteria in the same way you would add and remove Lifecycle State search criteria.
3. When you have entered all of your search criteria, click Search. You can also click Search without entering any criteria to view a list of all products. The Search Results for Product window appears.
You can show images for the product and modify search criteria. Show Criteria is a toggle button that displays the search criteria. When the search criteria are displayed, the toggle button becomes Hide Criteria.
Click (choose) to select the product. The Search Results for Product window closes and the system return you to the page to compare BOMs, with your selected product on the left. When you select a product, the lists are updated with options that are applicable to the product you have chosen.
* 
If you want to compare different BOMs of the same product, and you are not currently working on that product, you must select that product twice.
Click Clear Object Reference Value to close the Search Results for Product window and return to the page to compare BOMs.
4. On the BOM comparison page, there are two boxes that contain information for each BOM. Select your comparison criteria using the lists in each box. You must select criteria for both BOMs, even if you are comparing different variations of the same BOM.
For a product, you can select a BOM from the Bill of Materials list.
After you have selected the Bill of Materials, you can select a specific color, source, or destination.
You can enter a date in MM/DD/YYYY format to return the BOM as it was on that particular date.
5. After you have selected your comparison criteria, click Run. Both BOMs, matching the criteria you have selected, appear side by side.
