How can I keep DynamicZip from updating my manually created Tax Schedule IDs?
Create a tax schedule that contains a single tax detail having the appropriate tax rate. (Please refer to your Microsoft Dynamics GP documentation for instructions.) The Tax Schedule ID can be any non-zip type ID such as NVCUSTOM or NVSPECIAL. We recommend using the appropriate state code as the first two characters of the ID. The tax detail ID can be the same as the tax schedule ID.
With the Tax Detail Maintenance window open and active, select DZ Tax Detail Supplement. Type the appropriate address info. This will assist the DZ tax reporting process to sort the tax information appropriately. For more information please see the Report Sorting FAQ.
Manually assign the tax schedule id created above to the appropriate customers and/or sales documents.
To prevent DynamicZip from overriding the custom tax schedule assignment open the DynamicZip Setup window and in the Tax Schedule Selection section, choose to Update Blank & Zip IDs only.
