====== How do I do a clean re-import of the Rate & Boundary Database? ======

Simply re-importing the Rate & Boundary Database will refresh your current tax schedules along with their tax details. Under normal circumstances, this re-import is all that is required.

The following information is provided to facilitate starting over from scratch. This is **not** recommended under normal circumstances. 

**CAUTION:** When this method is used, you will return to the point you were at before you originally imported the Rate & Boundary Database and before you created any manual tax details and tax schedules. Typically simply re-importing is the best and safest approach. This method normally should only be used in the case of a new install of Microsoft Dynamics GP and DynamicZip.

  - On the Microsoft Dynamics GP menu, point to Maintenance, and then click Clear Data. 
  - Change the series to Company and insert the table Sales/Purchases Tax Master. (This is actually a group of tables which includes the Microsoft Dynamics GP tax schedules, details, period history, etc.) 
  - Click OK to clear data on this group of tables.
  - Open the [[dynamiczip:windows:DZ Table Maintenance window]]. 
  - Change the procedure to Clear Data. 
  - Insert the following tables and click Process to clear data on them:
    - [[dynamiczip:tables:DZ Update History table]] 
    - [[dynamiczip:tables:DZ Rate Set Index table]]
    - [[dynamiczip:tables:DZ RateSet Calculation table]]
    - [[dynamiczip:tables:DZ Tax Detail Supplement table]] 
    - [[dynamiczip:tables:DZ Tax Schedule Supplement table]]
    - [[dynamiczip:tables:DZ Tax Schedule Update table]] 
    - [[dynamiczip:tables:DZ Zip Address table]] (this will remove zip addresses for all companies)
  - At this point the tax details and schedules should be gone. You should now run the Checklinks process then re-import the Rate & Boundary Database.
