Customer master data creation

Question

Hello Folks,
I need some confirmations please :
1 . customer master data (cmd) is created at account group and company code level.
So, if a  customer is a customer of 3 company codes of a company , 3 customer master records needs to be created where the number range of the customer code being the same and the company code is different and the account group remains the same?
2. A  customer can buy from any sales area combination in company code, but only 1 customer master record is created ? If so, 1 customer code is for any Sales areas for a customer?
So, Sales area is data fields in a customer master record and only account group and company code and the customer code are key fields in the definition of customer master record?
Please confirm for me. Thanks.
regards
Ravi

Hi Ravi,
_Extension of the CMR_
a.     If the Customer is buying from under 1 Company Code and multiple Sales Areas then you need to extend the CMR for all sales area.
b.     However when the sales areas change the Customer No., General data and the Company code data does not change
While Extending the CMR by changing the Sales Area:
a.     In XD01 or VD01 enter the Account Group of the customer which is to be extended
b.     Enter the customer no.
c.     Enter the New sales area
d.     The system will take you directly to the sales area data
e.     The Company Code data and the General data cannot be chosen.
While extending the CMR for different company codes:
a.  In XD01 or VD01 enter the Account Group of the customer, which is to be extended
b. Enter the customer no.
c.     Enter the New Company code
d.     The system will take you directly to the Company Code Data
e.     The Sales Area Data and the General data cannot be chosen.
While extending the CMR for different company codes and sales Areas:
a.  In XD01 or VD01 enter the Account Group of the customer, which is to be extended
b.  Enter the customer no.
d.     Enter the New Company code
e.     Enter the New Sales Area
f.     The system will take you to the Company Code Data
g.     Then you can go to the Sales area data.
h.     The General data cannot be chosen.
Tables Used for CMR:
Table Name     Used For
KNA1         General Data
KNVV         Sales Area Data
KNB1         Company Code Data
Q. Why are there 3 Data Groups or 3 different Tables for one customer?
Ans. Since the Customer is expected to buy in more than one sales area and also in some cases in more than one Company code different data sets need to be maintained but however some data remain same, so to avoid data redundancy you maintain 3 different tables.
Hope this helps,
