Removing all duplicate records except one copy

[adam a]

Hello,

I have combined data from several sheets. The data is of product information that is sold in a chain of shops. I am trying to compile a master list of all products sold across the chain. In column A is the product NUMBER, in column B is the supplier number for that product. e.g.:


________Column A_________Column B

Row 1___1000____________20
Row 2___1000 ___________ 20
Row 3___2000____________30
Row 4___2000____________20
Row 5___3000____________30
Row 6___3000____________30
Row 7___3000____________20

REQUIRED RESULT:

________Column A_________Column B

Row 1___1000____________20
Row 2___2000____________30
Row 3___2000____________20
Row 4___3000____________30
Row 5___3000____________20


n.b. there are other columns of dat but I want the comparison for duplicates to ignore them (if possible). I have tried using ADVANCED FILTERS but this gets rid of ALL records that are duplicate and keeps unique ones only!

Any help is a lifesaver as project deadline for FRIDAY 8th JULY!!!!!

Regards

Adam

Good afternoon Adam a

The code listed below will do the trick for you. It will hide all rows containing duplicate information, so you don't lose the information - it just removes it from view. However feel free to alter it to delete the rows completely if you wish.

Sub HideDuplicate()
On Error Resume Next
Set UsrRng = Selection
For Each UsrCel In UsrRng
Dupd = UsrCel.Address
Dupd = UsrRng.Find(What:=UsrCel, After:=UsrCel, LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False).Address
If Dupd <> UsrCel.Address Then UsrCel.EntireRow.Hidden = True
Next UsrCel
End Sub


To use this highlight just one column that contains the duplicate information and then run the macro.

What happens if you select column A first (or make the list range just column
A)?

introduce a top row as header row
use data=filter=advancefilter -unique values

the creiteria range may be left blank or the same as database

I'd back up file first;
then Insert a "helper-column" to left of ColA
in new A1 enter =B1&C1 << to concatenate,
then Copy A1 down to A2000 (?);
Then do the Advance Filter option again checking the Unique Records option
(based on Col A).

Advanced filter should work fine if you select columns A and B when you
apply the filter

I think this is what I have been searching for. I need to delete duplicate addresses out of a list of thousands. This sounds like it will work but I have no clue how to write and then apply a macro to do it. How do I take the details below and apply it to my workbook? woodlot4atyahoo.com

Good afternoon Adam a

The code listed below will do the trick for you. It will hide all rows containing duplicate information, so you don't lose the information - it just removes it from view. However feel free to alter it to delete the rows completely if you wish.

Dupd = UsrRng.Find(What:=UsrCel, After:=UsrCel, LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False).Address
If Dupd <> UsrCel.Address Then UsrCel.EntireRow.Hidden = True
Next UsrCel
End Sub

This was never solved, was it?

So wow can I keep one row of a group of duplicates?

Example, the function deletes the red rows:

Row 1___1000____________20
Row 2___1000 ___________ 20
Row 3___1000 ___________ 20
