Expected system behavior.

When a new country is enabled, the new plant becomes associated with the sales organizations. This results in the addition of all new tax classifications to the existing sales organization and distribution channel.

When making updates to an existing product that has a sales organization, the new tax classification for the existing material organization level data must be maintained.

Related to the Mass Maintenance Product app, it verifies the consistency of the complete product, not just the modified part.

The changes to customizing for sales organizations/distribution channels can be reviewed in the SSCUI 102287 Assign Sales Organization - Distribution Channel - Plant.

Countries and Sales organizations may require multiple tax configurations for their products.
One way to determine what are the required taxes for a product is by using the "Create Material" app, as the mandatory taxes appear when setting up the Tax Data in the "Sales: sales org. 1" tab.

The following list presents the countries that have additional mandatory tax classifications beyond "TTX1" (Output Tax), along with their required tax categories: 

Ensure that the mandatory tax classification for the product is maintained.

The app "Mass Maintenance for Master Data" can be used to update the tax classification of several products.

Provide the required tax categories and values according to the desired Tax Classification.

In the Migration Cockpit app, for countries which require more than one tax classification, make use of the fields TATYP2 and TAXM2, TATYP3 and TAXM3, and so on, in the "Tax Classification" sheet. 
Note: Ensure that each country/region has its own row in the template file. The same product may have multiple rows (one for each country).
