1. In the course materials, common master data for Division, the diagram shows Customer master data and condition master data both shown at Sales org + Division level, without showing the Distribution channel.
Why is the distribution channel not shown?
Likewise, for common master for Distribution channel the diagram does not show the division level.
2. Can i confirm that Material master data we can specify a reference (common) Distribution channel but not a reference division.
Division in SAP is at the material level. Division in sales area is included for greater flexibility. Common division is used as one division which will represent all the material divisions the your company has. The common division helps you in
a. Maintaining the master data like customer master only once and you need not extend it to all the sales areas that get created only because of change in division.
b. Maintaining the pricing data becomes easy
c. As you are not overloading the system, it is not bulky.
So, you assign one division to all the available divisions. The reason for only representing sales org and division in the table is that you are first saying that these divisions belong to this sales organization. By this way you are establishing a link between sales organization and division.
Similarly you assing a reference distribution channel to a distirbution channel. Here also you are establishing a link b/w the Sales org and the distribution channel. Hence, you have only sales org and dbr chn.
Basically you will not reference a common distribution channel in the material. However, it depends on the business scenario. So, it becomes the implementors decision to do so after having a discussion with business. Usually materials are extended to each of the sales org and distribution channel combination.
Common divisions are not assigned to materails. These divisions in the material will help mainly in reporting and pricing for any business.
Hope this helps...
