P40082 Setup

Hello Team,

May I know what is exact use of the setup P40082.

JDE Manual States as below:

You use the Alternate Tax Rate/Area by Country program (P40082) to define the companies and alternate tax rate/areas for a country. Using this program, you define combinations among the following fields:

• Tax Area
• Company

You can define new tax rate/areas or import them from the Alternate Tax Rate/Area table (F40081). When you set up the company and tax rate/area for a country, the system stores these details in the F40082 table.

Please help to understand this in more details. Also confirm if this is mandatory Setup.
