Reset tax code function for prime contract invoices

The Reset Tax Code function uses the default tax code in the Job Cost Code table to update all references in the prime invoice. This process ensures that the tax codes in the invoice are consistent. This process does not affect any features or invoices.

For fixed-lump-sum contracts, the following items are updated:

• Items in the original prime contract, also know as the schedule of values
• Change order items
• Billed Retainage, also know as retention or holdback

For cost-plus contracts, with or without GMP contract details, the following items are update:

• Cost-plus invoice items
• Billed retainage

For unit-price contracts, the following items are updated: 

• Unit-price items in the original prime contract
• Change order items
• Billed retainage
