Issue using XEN to export BOM report

I am using XEN to define a BOM report and export it to excel.

Steps:

1. Filter the product for the components I what to show in the BOM Report 

- Filter data displays 250 components

2. Select Flatten View

3. Select Reference View

These options give me the report with Quantity I need to export to excel.

Issue: When I use the export function in XEN, I get an error message. "Export is not supported for large data having 10000 or more data at multilevel"

I am able to view the data using the options Flatten and Reference View as shown in the attached image.

Any suggestions? Methodology of product structure or performance tweeks to the server?

A workaround method is to select all in the list and copy/paste to excel.
