Copying Row With Prevent Duplicate Entries

May 13, 2009

I've got this code for prevent duplicate entries, But I wondering if it's possible to add a copy rows to it? For Example

Columns C
ItemID ItemName
11 QWE
22 ASD
33 ZXC

So now I enter 22 in ItemID for this working code it will pop up a MsgBox saying Aready exist, Is it possible to add a code so that it will copy the existing copy and paste into the active row?

Private Sub Worksheet_Change(ByVal Target As Range)
Dim r As Range
Dim ans As String
Const myCol As Long = 3
If Intersect(Target, Columns(myCol)) Is Nothing Then Exit Sub

How To Prevent Duplicate URL Entries In Cell In A Column

Mar 23, 2014

I tried to solve above problem using Data Validation formula. Data validation does not work if somebody copy paste the duplicate values,it works when somebody types duplicate values in next column. So if I want to enter lot of urls to a column then it is completely impossible to type so must have to copy paste from the browser. I have attached a sample sheet, howl to solve this problem either using formula or using Data validation in sample 1 and sample 2 respectively.

Looking To Prevent Duplicate Text In Cell

May 7, 2009

I have one main tab which I pull data from other various tabs. To match data the data, I create a "common unique ID", in other words I create a column on each tab and connect various cells with the ampersand.

So in each of the various tabs (and the main tab), I'll have a column with something like =A2&B2&C3

If the "unique ID" matches between the tabs it will pull back the desired phrase, or it will be left blank. (Just using an =IF(ISNA) formula)

If you have followed so far, on my main tab, I have a column for each of the various tabs. The information I am trying to match could be on any of the tabs, so I need a column using an =IF(ISNA) formula to attempt to match each tab. So, on the main tab, there are several columns which might have the phrase I am looking for. I use another ampersand function to add those columns. My problem is that occaisionally, what I am looking for is on multiple tabs. So, if I am normally pulling the phrase "Pending Loans Report" when a match is made, if it is on two tabs, the cell will add it twice "Pending Loans ReportPending Loans Report"

I realize this is confusing, so I attached a spreadsheet. The "main" tab I was referring to is sheet1. I really simplified it down to post here, but I think the main idea of my problem is still evident. The problem is line 15. Note how column M has "Pending Loans ReportPending Loans Report" - I'd like it to only say this phrase once. The macro pastes special values at the end, but I've highlighted some cells in red which show the formulas I used for that column. Columns N, O, P, Q, etc. all have virtually the same formula.

How To Prevent Duplicate Data Being Pasted

Jan 14, 2013

I have a worksheet that you can enter in

Forename, Surname, Area, D.O.B

This has a macro assigned that copies the data and pastes it into another worksheet at the next available row.

Now this works fine, but I want to be able to identify if the data already exists in the other worksheet then prevent it from being pasted and give an error message that the person already exists in the database.

Is this possible?

Prevent Duplicate Entry From Textbox Into Different Worksheet

Jun 12, 2009

I have a entry form in which i want to register customers. the first field is the customer number (which is unique(created by me) for every customer). This is TextBox 1 in the document. I would like to search for duplicates in worksheet 2, collumn A, when pressing "enter" to move from TextBox 1 to TextBox 2. A search for duplicates should start and a message should appear " duplicate found" if found, otherwise continue to TextBox 2 for further entry of information.

Please see my attached document for clarification.

How To Prevent Duplicate Records From Being Entered On Recording Sheet

Feb 9, 2013

I have a created recording sheet (attached) for the purpose of recording moths. I send this sheet out to those recorders who live in my county and at the end of the year they send the filled in sheet back to me. Over time I have put safeguards onto the sheet to ensure that I get the cleanest data returned to me. However, there is still one area which is giving me problems - users entering duplicate records.

Some formula which will stop recorders from entering those duplicate records. There are many columns on the sheet which recorders have to fill in with information, but as far as the duplicate records are concerned it is where the same information is entered into columns C, F and J that I'm having a problem with. It would be great if, when the same information was entered in these columns that the affected cells were highlighted in some way and if an error message appeared saying 'Duplicate record, either delete or alter grid reference'

I have entered two test duplicate record on the 'macro moths' sheet of the attached file : Test Recording sheet.xls‎

Prevent/Remove Duplicate Data From PivotTable Source

May 29, 2008

I am working pivot tables off of one large excel spreadsheet for my data. I have multiple pivot tables on each of 5 worksheets. The problem is this. Every other week I am sent an updated spreadsheet with the same column names each week which I then copy and paste it into the spreadsheet of the last one. When I refresh the pivot tables, I end up with duplicate field sets. For example, on column in the original data sheet is gender. On the first sheet I went through and renamed the "M"'s and "F"s to be "Male" and "Female" so that it is better looking when printed. Now when i get the new information and copy and paste it to rplace the old, and refresh the pivot tables, I end up with "Male" "Female" AND "M" "F". Now the "Male" and "Female" fields are empty and the "M" and "F" fields have the information. Is this a result of me renaming the fields?

Duplicate Entries

Sep 24, 2009

I have been trying a number of different functions!

I have the following countif function that is searching a worksheet (Cases Closed) for the name John in Column O and excluding Solutions in column x. The problem I have is there are duplicates cases in Column C that are being counted two and three times.

Is there anyway to have the following function exclude duplicates records in Column C? Just count unique records in Column C?

=(COUNTIF('Cases Closed'!O:O,"John"))-(COUNTIFS('Cases Closed'!O:O, "John", 'Cases Closed'!X:X, "*Solution*"))

How To Combine Duplicate Entries

Apr 23, 2013

excel.jpg

Basically I've made this up myself because what ill be working with has 100s if not 1000s of rows with many different product numbers that's quantities are different. What I've been able to do up to now is sort the spreadsheet by the product number so all the same rows are next to each other. My problem is however I need a speedy way of making these duplicate rows become one but add the total quantity basically everything in the left screenshot into the one on the right. What I've tried up to now is sorting them so there together and manually adding them up and putting them into one of the rows quantity, then delete the rest. takes to long. Another was to make a row underneath the rows I need into one but that takes more time than manually adding and deleting the rest.

Clear Duplicate Entries

Jul 14, 2008

I am trying to find a macro that will clear duplicate entries in a column of data, and then move to the next column and repeat the process until it gets to a blank column.

There are blank cells between entries in a column. I need to keep the data unsorted as the cells are linked to others in the row, therefore I dont want to delete the cells, just clear the contents.

Highlighting For Duplicate Entries

Nov 24, 2009

I would like to check column B and if any of these values match values in column J hightlight the cell on the same row as the match on column E green. I don't know much about excel but this would be a tremendous help because i'm looking through quite a bit of data. I've tried using conditional formatting and i can't seem to get that to work for my needs. Let me know if you need anymore information.

Eliminate Duplicate Entries WITHIN A Row

Feb 8, 2010

I have a table of data like this:

A , 1 , 1
B , 2 , 1
C , 3 , 4
D , 1 , 3
E , 3 , 3

I need to eliminate duplicate entries WITHIN a row. So, I need the table to become:

A , 1
B , 2 , 1
C , 3 , 4
D , 1 , 3
E , 3

Is there an easy way to do this for a large sample? Also, there are actually more like 8 columns of this data, if thats important.

Preventing Duplicate Entries

Dec 11, 2012

I've generated a sheet where, based on the total run hours of a generator set using a given fuel type, we can determine which engine to run on what fuel when. The problem I've run into is that if more than one engine has the same runtime, the chart returns just the lowest numbered engine and eliminates the remaining engine(s). What I'm trying to do is make it so that when this occurs, the suggested engines show up in numerical order. For example instead of 1, 1, and 1 showing up on the chart, something like 1, 2, and 5 will show when they all have 0 run hours. I've attached my chart below with some engines having the same runtimes. RunOrder.xlsx

Stop Duplicate Entries In A Row

May 25, 2009

=COUNTIF($A$1:$D$100,A1)=1
however I don't know how to change that to suit my needs (or even if it is at all possible to change it to suit my needs)

I will try my best to explain how my spreadsheet is set up as unfortunately I am at work and I can not use the method to show you the spreadsheet.

My spreadsheet:
I already have Data Validation in use from a list that I created. I use the same validation list in Columns C, E, G, I, K-BA

I also use validation list in other cells, and it is OK if these are duplicated throughout the row.

The only cells that should not contain duplicate information are the ones from C, E, G, I, K-BA

Basically I want to stop someone accidentally chosing the same option from the list within the same ROW.

Just in case it makes any difference I should let you know that I have already had help from the forum regarding macros for this same spreadsheet, here is the macro that is currently running just in case it makes a difference if there is an answer to my current problem.

Option Compare Text 'A=a, B=b, ... Z=z
Option Explicit

Duplicate Entries, Validate Only One

Jan 22, 2007

In my spreadsheet, on ( sheet A) I pick up a value to a range (O2:O22) from other worksheet (sheet B), the value is validated when a cell in the same range but other column (A2:A10) reach a specific criteria.

But in the same column if the criteria is typed again I gone a have the same value on range( O ), and I dont want that, because this value represents a total for a day, and is to be added to other cell.

I'm using this, to pick up the data
Ex:
(A2:A10) Criteria
(O2:O10) value picked up

on SheetA, Sumif(sheetBA10:A40,A2,SheetBK10:K40)

How can I count only one of the values picked up from sheet B?

Find Duplicate Entries

Feb 14, 2007

Got a workbook with 4 worksheets and sometimes we need to cut and paste a row from one worksheet to another, now thats easy now as we are all human and sometimes it gets copied and we have duplicate logs.

Now each sheet has usually not got that many rows in it, but that spreadsheet is getting sent to the highest people in the company and any mistakes look poor.

What i'm looking for is a way that i can highligh any rows that a duplicated in each worksheet. I can do it in each worksheet using conditional formatting with something like = COUNTIF($A8:$A$20,A8)>1. but don't know how to check that is not on any other worksheet. On every worksheet only need to check Col A for the duplicate information
