Topic: Hide the default tax rate shown when processing Purchase Order Entry

During the processing of Purchase Order Entry  it shows the tax rate I previously set up in  Setup-Tax Type-the Default Rate %.
Is there a way for me to hide the tax rate that shows during the processing of Purchase Order Entry.

Please let me know what file I need to edit in coding.

Thanks

Setup->Company Setup->Suppress Tax Rates on Docs (ticked).
