[JB] How to add tax to a JB Progress Invoice that has already been interfaced

Change made to the JC Contract Master will only affect new bills. If you add the tax code to the Contract Master, future bills will have the tax code and calculate tax.

For an existing bill that has already been interfaced, add the tax basis and tax code to the bill using the Item SM/Tax tab in JB Progress Billing.

1. Open JB Progress Billing, and open the bill that needs tax added.
2. Go to Item SM/Tax tab
3. Scroll right to find the columns for Tax Code, Tax Basis and Tax Amount
4. Enter in the Tax Code and that Tax Basis. The Basis should be equal to the "This bill WC Amount" for this item on the items tab.
5. Tab off and the system will calculate the amount of tax.

NOTE: These changes will put the bill in to change status, so the bill will need to be reinterfaced using JB Interface
