enhancing Column A through Column B

Hello,

i have a list containing six columns A,B,C,D,E,F in Sheet"original". It seems like follows ( the columns C,D,E,F are not relevant for macro therefore i am puting only Column C as example for the Columns D,E,F):

Col.A      Col.B      Col.C
A	B,C,D,E	FF
S	A,F,G	FFG
T	N,O,C	NFS
U	V,X,W	EES
Y	C,D	NNO
Z	A,B,C	KKL

Now i need a macro which enhances the column A through column B. The macro should put those members of Column B in Column A which donot already exist in column A. These new entries should be done in another sheet "new". For example the first entry in Column A is "A" and the corresponding members to that are "B,C,D,E" in column B. Now as far the corresponding members "B,C,D,E" dont exist as members in column A they should be added one after another to the new sheet to column A. This new entry in Column A in sheet "new" should have the original member from column A the "A" and "C,D,E" (not "B" itself") members in column B in sheet "new". All the corresponding members of other columns to the original column A should also be pasted to the new sheet in corresponding columns. No Duplicates in Column A in Sheet "new" should be allowed. After running the macro it should generate the following new list in sheet "new".

col.A      col.B      Col.C
B	A,C,D,E	FF
C	A,B,D,E	FF
D	A,B,C,E	FF
E	A,B,C,D	FF
F	S,G,A	FFG
G	S,A,F	FFG
N	T,O,C	NFS
O	T,N,C	NFS
V	U,X,W	EES
X	U,V,W	EES
W	U,V,X	EES

I am uploading an image and an excel file. The colors in the image means nothing but only an effort to make the problem understandable.
