Assembly Comparison

The assembly comparison section facilitates comparison between two parts or assemblies that exist in the system.

To perform assembly comparison:

The parts/assemblies can belong to any two of the following types of container entities:

• Programs
• Versions
• Variants
• Products
• Revisions

The comparison between two parts/assemblies can be done using two methods:

1. Compare on Part Number
2. Compare on Item Number

Consider the following illustration that represents two assemblies and their constituent sub assemblies and parts.

Figure 1. Example Assemblies

The Compare on Part Number option compares two assemblies and tries to first match the parts / sub-assembly numbers at the same levels first before performing the delta comparison between the two parts. The system will compare the parts numbers of the parts in the selected assembly disregarding their position order in the hierarchy. For example, (referring to the preceding illustration), when 01 - Sub-Assembly 1 is compared with 01 - Sub-Assembly K even though the order of the parts in the two assemblies is different, since the comparison is based on the part numbers, WA will compare part 104 - Part 4 in 01 - Sub-Assembly 1 with 104 - Part 4 in 01 - Sub-Assembly K.

The Compare on Item Number option compares two assemblies and tries to match the parts and sub-assemblies based on the position of the same in the part/assembly hierarchy. The part numbers of the parts in the assembly is disregarded and the comparison is performed only based on their position and order in the assembly hierarchy. For example, (referring to the preceding illustration), when 01 - Sub-Assembly 1 is compared with 01 - Sub-Assembly K even though the part numbers of the parts in the two assemblies is same, since the comparison is based on the item numbers, WA will compare part 104 - Part 4 in 01 - Sub-Assembly 1 with 103 - Part 3 in 01 - Sub-Assembly K.

1. Click Parts Catalog > Assembly Comparison.

   

2. In the Assembly Comparison page, click the first Select Part icon to select the first part/assembly.
   
3. In the Part Selection dialog box, search for the part or assembly that you want to use as the Part 1 of the comparison.
4. Click the required item in the Part Number column.
5. Click Select Part.
   The part/assembly is selected for comparison, and the part number and code of the selected part is displayed on the page:

   

6. Repeat the same steps to select the second part/assembly to be used in the comparison.
   The part number and code of the selected part is displayed on the page:

   

   The results of the comparison are shown in the results section of the page.

   

   The DELTA column of the report shows one of more of a pre-defined set of icons to represent the meaning of the comparison results for each row of the result. To understand the meaning of each of the delta status icons refer to the table below.

   - Check	No delta on this part.
   - Center of Gravity	The part has a different CoG between the snapshots.
   - Weight	The part has different weights between the snapshots.
   - Cost	The part has different costs between the snapshots.
   - Right Arrow	The part exists only in the second snapshot of the comparison.
   - Left Arrow	The part exists only in the first snapshot of the comparison.
   - 123	The part has a different quantity between the Snapshots.
   - Revision	The part has a different revision between the Snapshots.

7. Click the Compare on Part Number icon to perform the comparison based on the part numbers.
   The comparison results are refreshed and the selected type of results are displayed.
8. Click the Compare on Item Number icon to perform the comparison based on the item numbers of the parts in the assembly hierarchy.
   The comparison results are refreshed and the selected type of results are displayed.
9. To export the comparison results to an Excel file, click the Report icon.
   The results will be exported in tabular format to an Excel file.
