Organization Structure for multiple countries

Hi,

We are setting up GLOBAL support organization. Our support organization includes following countries:

1. China

2. Japan

3. Korea

I am reading the SAP blog from forum. It says that,

"Enter the necessary data in the address tab (City and Country). In the Function Tab, Select Service and Service Organization. In the Attributes Tabs, check for the attribute maintenance Scenario: Service that you have a value in the attribute Country. Be aware that the basic organizational determination process is based on the Country value. This means that all of your business partners should have the same value in this attribute. If you have more than one country then you should create several organizations".

My query is:

In my organization structure, it involves three countries (China, Japan & Korea). I have included all the three countries in a single organization structure. But as per the above statement, should i need to create three organization structure for three countries?

Regards

Kumar
