Custno 1 & 3 Adress & City match, custno3(faxphone) & custno6 (resphone) matching so these three records should match and get same groupid
custno2 record fields not match with any fields so that one will get one groupid.
custno4 & custno5 matches with res phone & business phone so these both reecords get same groupID

so any phone no filed matches with any other customers any other field consider as matched.

any email1 or email2 matched with any other customer email then all matched customer no get same groupID.

Can you please help here olafhelper. Thank you

so when ever the phones matches (any customers any phone nos ) then assign one generic no.

if email 1 or email 2 matches with any other customer group. but for addr1 and city both has to match with other customer.

Thank you
