You can create BOM balloons for components defined as flexible within an assembly. The BOM balloons for flexible components are created regardless of the attribute you set for the repeat region. That is, you can set the attribute for the repeat region as Duplicate or No Duplicate.

For example, the following assembly consists of two springs (DAMPER_SPRING) that are defined as flexible components, each with a different flexible value. The attribute of the repeat region is set to No Duplicate. These two springs are represented in a single row with an identical index number. However, the quantity appears as two. When you create BOM balloons for the first time, a single balloon is created that represents all instances of flexible components with the same name. However, when you create BOM balloons the second time, each instance of the flexible components with the same name is assigned a balloon with an identical index number.
