Bilal,
Firstly refer to :

Now, let me try and explain to you briefly.
Consider a table. A table has a certain structure. This structure is defined by its fields. For instance a table for sales orders will have SO Number, Sold to Party, Ship to Party, Reference PO, Delivery Date etc... These fields, constitute the structure. Then there rae records. For the sales order table a record will be
So number=100001
Sold to Party = ABC
Ship to Party = XYZ etc
This is a record.
Now try to draw an analogy with POS. The Master Planning Object structure constitutes a structure. You assign characteristics to an MPOS, which are equivalent to teh fields in the table. For instance the standard DP MPOS 9ADPBAS conatins the follwoing characteristics:
9ABRAND     Brand
9ALOCNO     APO Location
9ALOCTO     APO Destinatn Loc.
9AMATNR     APO Product
9AVKORG     Sales Organization
This structure is called the MPOS. It defines the lowest level at which data is storeed and planned.
Now draw an analogy of teh table records to the CVC. A characteristic value combination is a record with values assigned to the characteristics of the MPOS. For instance one CVC could be:
9ABRAND     PEPSI
9ALOCNO     NEW YORK
9ALOCTO     PARIS
9AMATNR     PEPSI CAN 330 ML
9AVKORG     001
This is ONE CVC. similarl;y for the same MPOS you can have another CVC:
9ABRAND     PEPSI
9ALOCNO     NEW DELHI
9ALOCTO     BANGALORE
9AMATNR     PEPSI PET 500 ML
9AVKORG     002
Similarly you can have thousands of CVCs for the same POS.
So, MPOS is nothing but just the structure which defines what are the plannable characteristics. CVCs are records, or values assigned to MPOS characteristics...
MPOS: /sapapo/msdp_admin
CVC: /sapapo/mc62
I have tried to draw an analogy so that you understand better. hope this helps.
I would sugegst you to purchase "Supply Chain Planning in SAP SCM by Jorg Dickersback. Its an awesome book for starters.
