Import Scenario - FS Equipment (Target Equipment) - Update component inventory and serial number

Hello Community.  Here’s my challenge to be solved:

1. Equipment already exists (FS205000) 
2. When importing the equipment, Component records automatically added per the model equipment configuration
3. I need to update the components with Inventory ID and Serial number

• I get an error because the import is trying to create new records and you can have only one per component ID.  My import scenario references the line number and the component id but still doesn’t update that row.

What am I missing?

Thank you
