SAP SD - Enterprise Structure.

I am not going into detailed procedure of creating ES. But I am giving you ES image. Let us see how the ES of a company looks like.

SAP SD - Material Master.

Here in Master Data after the CM, Material Master is another data existing in the system. Before creating Material Master Prerequisites are Assigning Company code to fiscal year variant (FI role), Assigning Chart of Accounts to company code (FI role). Maintain Company codes for Materials management. (MM role), Define Material types (MM role).
Here SD roles starts to enter Material Master Data. Following images will guide us to create MM.(Before Last image save the configuration).

SAP SD - Customer Master.

Here; I am giving you the image to give us idea about creation of Customer Master (Data).
We need Account group, Number range, Partner Determination Procedure to be assigned.
Use standard group for practice (ex: '001-sold to party') .
Created number range '09' and assigned to above Account group.
Let us see how the Customer Master will be created. Following images will guide you to create CM

SAP SD Variant Configuration

How to do work out on Variant Configuration?

I assume that you created Enterprise structure; let us think it is like below structure of 'ABCD Company.

Company (FI) - ABCD
Company code (FI) - 00AB
Sales Org (SD) - ABCD
Distribution Channel - AB
Division - AB
Sales office - ABCD
Sales group - ABC
Plant - ABCD
Storage location - ABCD
Shipping point - ABCD

Below picture will say how the Org'n structure looks like.














To proceed for VC settings we need Pre-requisites like
Fiscal year variant (K4 or V3) - (Tcode OB29)
Assigning fiscal year to company - (OB37)
Chart of accounts for company - (OB62)
Maintenance of Company code with Material Management (Maintain Company codes for Material management) - (OMSY)

Proceeding with MRP group Overall Maintenance (OPPZ)
Define MRP group for Each Material type (KMAT)
Define MRP Controllers
Defining Scheduling Margin Key.

The above setting will be needed from FI and MM module perspective.

(However here when looking to go ahead with Fiscal year by taking V3; I am unable to proceed further where I can't do MCC for MM, need you guru's help on this topic).

From here SD Consultant role will be started.
