How to override customer level exempt Rules when importing (OM Import) invoices to AR?

Hello Team,

We have a requirement where we need to calculate tax based on the tax_exempt_flag given on sales order line level. ex if tax_exempt_flag='E' line should be exempted for tax, if tax_exempt_flag='S' then tax should be calculated irrespective tax rules given on the Customer level.

Are there any profile options gonna help?

Ex: Sales Order: 12345 having 3 lines, on all lines tax_exempt_flag='S' but at customer level there is a tax exempt rule setup. Here in this case we need tax to be calculated irrespective of customer level tax rule.
