HI Venu,
Answers to sme of yourquestions:
2. Scheduling is basically a process which system users to comfirm whether a particular material could be delivered with in required delivery date. system by default is set to do backward scheduling first, if the confirmed delivery date falls beyound material availability date then syetm does forward scheduling to determine the Confirmed delivery date and system gives the new confirmed delivery date. system takes into account the following for scheduling:
a. Order Date
b. Material Availability date
c. trasnportation planning date
d. Loading Date
e. Goods issue date
f. Required delivery date
3. SIS / LIS: Go thr below links:

4. TAD: Service Item
TAD gets determined based on Sales doc type + Item category group {OR + LEIS (Service Item category group)}
TAX : Non Stock item and gets determined based on Sales doc type + Item category group {OR + NLAG (Non stock material Item category group)}
Item category gets determined in sales document based on 4 standard rules:
sales doc type  + item category group + useage + higher level item category.
& we use item cagetory group in material master - sales org1 view.
5. LEIS - is a item category group for service items, and this might have delivery also
DIEN - is a Item category group for serivce items without delivery
6. KB, KE, KA & KR are document types which are used in Consignment scenario
KB - Consignment Fill up
KE - Consignment  Issue
KA- Consignment  Pick up
KR - Consignment  returns
And you have billing in only 2 of consignment scenarios i.e., Issue and returns and usually we use Billing type F2.
Go thr below link for Consignment:

7. S1 / s2 etc are basically Cancellation Billing type. We create invoice using F2 and this is cancelled using Cancellation Billing type S1. This canbe configure din VOFA - Billing ytpe Config (SPRO)
8. Picking Location determination: Is a STandard determination and this works on Standard rules:
Shipping Point + Lant & storage Condition (this data is given in Material Master - Plant / storage View 1)
We know that a particulat material is kept in a particular bin and we can pick up but to map tihis activity in sap we use Picking Location determination.
9. Schedule line is bascially has infromation related to Shipping & procurement and this is a part of Sales document structure.This is controlled by Schedule line category and this is again a standard determination and gets determinesd on Item catgeory + MRP type.Any where you need to deliver a material you should have information about when the material woudl be delivered etca nd this is stored in Schedlue line.
Scheduling agreement is a type of contract.Go thr below link:

10.Contract is agreement between a company and sold-to-party. you have 2 types of contracts - value contract and quantity contract. go thr below link:
http://sap-img.com/sap-sd/sap-sd-scheduling-agreement-vs-contract.htm
11. with ref to contract you create a sales orders and these sales orders which are created with ref to contract within the validity period of contract are called as Release orders.
12. NMS / WK1 / WK2 etc are document types for Contracts: go to VA41
WK1 - general value contract
WK2 - material value contract
GK - Master Contract
Master Contract:
The master contract is a document under which you can group contracts as lower level contracts. It contains the general terms which apply for all the lower level contracts over a specified period.
Use
You group contracts as lower level contracts under a master contract to ensure that
The terms in the master contract are granted in all the lower level contracts
The data in all lower level contracts remains consistent
You can group the following documents under a master contract:
Quantity contracts
Value contracts
Service contracts
The link between the master and lower level contracts is controlled by the referencing procedure which is assigned to the master contract type in Customizing. The referencing procedure determines which data is copied from the master contract into the lower level contracts
Structure
A master contract contains header data only. In the master contract, you can record:
Business data
Partner data
Contract data
Billing plan data
On the overview screen of the master contract, there is a list of all the lower level contracts which refer to it. You can branch from this list into the individual contracts.
Hope this clarifies.
