Conflict Errors When Synchronizing
Feb 14, 2006
We have multiple users using the same database as local copies on each of their PC's. they are entering information in specifically assigned areas and no one is overlapping in their work areas. The users then synchronize to a master database that is on the network to transfer their info.
When synchronizing we are beginning to conflict errors, and the message is hard to decipher. Below is an example:
"Update/Delete conflict: Another replica also updated this record. This record lost the conflict. Either resubmit your update or delete the conflict record."
It then shows two columns. Column 1 has the option to "Keep exisiting data" an dcolumn two has the option to "Override with conflicting data".
Technically, when synchronization happens, data of the user who is synchronizing overrides existing data in the master database in the same record(s). In that spirit, what is the 'existing' and 'conflicting' data referred to in the message?

When I synchronize my replicas not all the data is being updated. What would cause this and how can I fix this?

hello. can anyone help me with replica conflicts?
i need to work with 10 replicas and synchronize with a master, but anyone can make changes and modify the records on the other replicas. is there a solution for that? why access doesn't recognize the changes as a conflict?
Thank you all.

Hi,
I'm a student learning how to use Access for my class project (Information Technology in a Global Society), and I chose to work with databases (even though, frankly, I'm technologically challenged). I've already finished making a very elementary database (tables, form, and a macro or two), but I was wondering if there's any possible way to synchronize the material in each table in such a way that changing the information in one would automatically update information in the other.
(I have one main table, and several other sub-ones with the exact same information but only parts of the main table. By this, I mean I created a main table with every student's Extended Essay topics, along with their supervisor as another field. Each supervisor oversees an essay for several students, so I created sub tables for each supervisor with the information of only their students.) What I'd like to know is if I can keep one main table with every supervisor's information and separate tables for each supervisor -- while, at the same time, having the main table update with the information that's added to the sub-tables by the supervisors.
I considered using Relationships, but after going through the threads here concerning relationship issues...I got even more confused.
Any help would be greatly appreciated.
<3, Patti

Hi, Could anyone please help me!
I am trying to create a sub-form which achieves the following.
When you select a vendor from a combo-box, only the software that is manufactured by that vendor appears in a data-sheet form view.
I have tried to create a secondary form which shows all the software and saved this. And then created another main form which has a combo-box for listing and selecting a software vendor. I have then dragged the secondary form into an area of the main form. Now i am just trying to figure out how to synchronize the two forms so that when you select a vendor, only software manufactured by the vendor is shown.

How do I make the name appearing in my combo box to change to match the name displayed when the record navigation buttons are evoked. Currently, when I use the navigation button, the form scrolls to the next record, but the name in the combo box does not change to match the new record?

I have a database that is replicated and in my attempt to synchronize a message keeps popping up "Synchronization between replicas..... and ....... failed. The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.
The problem is I don't know what field in what form or in which replica this is referring to. Please help!!!!

Hi There,
I want to synchronize 2 comboboxes (actually 3, but let's start with 2)
On a form I have 2 comboboxes:
- CompanyType (FK fkCompanyTypeID in table Contacts)
- Category (FK fkCompanyCategoryID in table Contacts)
Let's say we have companytype CT1 until CT10.
For CT1, CT2 & CT3 I want to choose a catagory, so the combobox must be 'enabled'.
For CT4 until CT10 the Catagory combobox must be disabled, so that I cannot choose a category value.
Actually I want to choose 2 catgories (2 comboboxes) for CT1 until CT3.
But I think that an explanation for the example above is sufficient for me.
Both comboboxes are filled by a Select Query, and the values are filled in a separate table. (Table CompanyType (PK pkCompanyTypeID) & Table CompanyCategory (PK pkCompanyCategoryID)).
Can someone please help me on this issue? :confused:
Thanks in advance for your reply,
Greets,
Quinten

This is very bad. We're losing data changes when we run a synchronize on an Access database.
A client wanted to use replication so he could have several people using the same database and then update everyone's changes. (It turns out that he's not used that feature.)
The client was unable to get the replica to work on his machine, so he uses the master version.
Instead, we've used replication to allow me to make changes in the database structure while he makes changes in the data. (Obviously, it would have been better to split the database in two parts, but it's too late for that now.)
Here's my process when I need to update his copy:
1. Synchronize between my master and replica.
2. Copy master to CD-R. (We're not on a network.)
3. Synchronize between client's master and replica.
4. Send a copy of master to client.
5. Open my new version of master on the client's computer and synchronize with his replica copy.
When we do that many of his recent changes disappear.
Why is that? They don't even show up as conflicts.
What are we doing wrong? Are we totally abusing the concept of replication or what??
I'm stumped. I appreciate any suggestions or thoughts.

I have a form with a text box from a table (cus. ID) and when I input that cus.ID into that text box I would like for that data to be stored in the appropriate table (customer) and also in the bridge table (customer purchases). Is there any way to input the data once into a textbox on the form and have it recorded into two different tables? Please let me know. Thanks

on my laptop, i have an access front end with tables linking to sql server personal edition.
i open a linked table, edit a field, and i get a write conflict error message 'this record has been changed by another user since you edited it', and the save record button is not enabled
i have many linked tables, but this is the only table that gives me this error. i have deleted the table in sql server, and made a new table, and started the link process again, but still the write conflict.
also, as i dont know if this is related.
when i get tothe screen to link the tables, i see 2 table names prefixed with a "~", however, when i go into sql server, i cannot see any tables prefixed with a "~"
any responses would be most appreciative, as my project has effectively stopped until i can resolve this.

An application that I made was created in Access 2000 as I was told that all users had at least this or newer. Of course a user with 97 popped up. Instead of having them purchase 2000 or newer I converted my app to 97 version. I expected troubles with references. So far this has only been a phone conversation and I plan on going there later today. The user says hitting alt/F11 does nothing... no code window comes up. I had her look through the menus for the code window but she says there is nothing there. She is getting runtime 3433 (she thinks) and unrecognized database format when trying to open a form. The database did open when holding the shift key though.
Before I go there, how do I open the code window for 97?
Any other suggestions? I bet this is a reference thing but there may be a problem with their access install too. There are 2 users at this location with the same issues... at least it sounds like it.

Hi,
I am keep on getting Write Conflict whenever I check a check box called chkHCE. There are over 3000 records and it's happening for every records. I would understand if it's happening once in a while but it's happening for every records.
Please suggest. I attached the error print shot. The data souce is a qry but updatable query. The query has two tables tie together. I never had any problems. Can anyone share their idea Please ???
Thanks
Code behind the chkHCE
Private Sub chkHCE_Click()
If Me.chkHCE.Value = True Then
Me.HCEInitialPrepared.Enabled = True
Me.HCECompletionDate.Enabled = True
Me.HCEType.Enabled = True
Else
Me.HCEInitialPrepared.Enabled = False
Me.HCECompletionDate.Enabled = False
Me.HCEType.Enabled = False
End If
DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
Me.CWSubform.Requery
Me.PlanWeight.Value = Me.PlanWeightCalc.Value
End Sub

I am using an unbound form (based on VBAUnbound.zip) to enter records into a table. following is an excerpt of the code:
Code:.AddNew .Fields("Catalogue_Code") = Me.txb_ip_cataloguecode .Fields("Base_Metal") = Me.cmb_ip_basemetal .Fields("Paint_Type") = Me.cmb_ip_painttype .Fields("Color_Family") = Me.cmb_ip_colorfamily .Fields("Metallic") = Me.cbx_ip_metallic
In the form, for all fields left blank, the code above places a NULL in the table.
I also have a form to search the same database which uses a following kind of SQL string:
Code:SELECT M_Paint.* FROM M_Paint WHERE M_Paint.[Base_metal] Like '*' AND M_Paint.[Paint_Type] Like '*' AND M_Paint.[Color_Family] Like '*' AND M_Paint.[Metallic] Like '*';
This search does not pick records with any fields with NULL if looking for 'Like '*''... which is obvious.
I have tried replacing NULL with ' "" ' and then the query works but I have to manually do this replacement. I have tried putting ' "" ' as the default value of all the combo boxes to see if that changes anything but have had no luck.
My options are:
- Modify my SQL string to include NULL in the search
- Make sure that a zero length string is added to the fields by default when no value is specified
- Anything else that I cannot think of
I will deeply appreciate help for any of the three options... I am out of clues!
Thanks a lot

Hello All,
I've created a query that resets a table entry called "Drum" to null if I change the record "Cable". This process works, except I get the following error when I do so:
" Write Conflict
This record has been changed by another user since you started editing it. If you save the record, you will overwrite the changes the other user made.
Copying the changes to the clipboard will let you look at the values the other user entered, and then paste your changes back in if you decide to make changes.
[Save Record] [Copy to Clipboard] [Drop Changes] "
I have set warnings to false but this still comes up.
Does this mean something is wrong with my method of updating the table? If not, is there any way I can stop the warning coming up?
Thanks to anyone who helps,
Bakerboy

I am working with a linked table that has a field [Originated Date]
I have created a query for this table and on the criteria for [Originated Date] I put the following:
Between [Forms]![Date Input]![StartDate] and [Forms]![Date Input]![EndDate]
I am using a pop up calendar to populate [StartDate] and [EndDate] fields on the form.
The format of the Date field in the linked table is "Text" not sure if this is the root of my problem ?
When I run the Query Manually and input the [StartDate] as yyyy/mm/dd and the [EndDate] as yyyy/mm/dd the query returns the desired results; However when I run the query with from the form It does not return the desired results.
It is driving me crazy not sure where the discrepency is ?

I searched this one and found that someone else had posted the same problem 2 years ago, but since no one replied to that one... I'm still stumped.
I have a set of subforms, each on a separate tab of the main form and pulling from the same table. I have code triggered on after update so that changes to a control on subform A will make changes to several controls on subform B (specifically, disabling the control and deleting any value). When I switch to subform B, I get a message saying:
"Write Conflict: this record has been changed by another user since you started editing it. If you save the record, you will overwrite the changes the other user made. Save record, copy to clipboard, drop changes"
Please help!

Hi all,
I have followed the advice on this page of 'how to update stock levels automatically' in access.
http://support.microsoft.com/default.aspx?scid=kb;en-us;252813
I implemented this in the Northwind database and everything was fine. I implemented this in my database (which is very similar to the northwind in structure!) and receive this error:
"WRITE CONFLICT
This record has been changed by another user since you started editing it. If you save the record, you will overwrite the changes the other user made. Copying the changes to the clipboard will let you look at the values the other user entered and then paste your changes back in if you decide to make changes."
I have no idea how this is happening. Can anyone throw some light on this? Any advice will be greatly appreciated.
Regards

I will try and describe my issues as best I can.
I have a NotOnList Event on a Combo box.
Dim strSQL As String
Dim i As Integer
Dim Msg As String
'Exit this sub if the combo box is cleared
If NewData = "" Then Exit Sub
Msg = "'" & NewData & "' is not currently in the list." & vbCr & vbCr
Msg = Msg & "Do you want to add it?"
i = MsgBox(Msg, vbQuestion + vbYesNo, "Unknown Problem...")
If i = vbYes Then
strSQL = "Insert Into TroubleShootingGuideTBL([Problem]) values ('" & NewData & "')"
CurrentDb.Execute strSQL, dbFailOnError
Response = acDataErrAdded
Else
Response = acDataErrContinue
End If
This worked just fine until I added an AfterUpdate Event used for Cascading Combo Boxes.
On Error Resume Next
Problem.RowSource = "SELECT DISTINCT TroubleShootingGuideTBL.Problem " & _
"FROM TroubleShootingGuideTBL " & _
"WHERE TroubleShootingGuideTBL.SystemGroup = '" & SystemGroup.Value & "' " & _
"ORDER BY TroubleShootingGuideTBL.Problem;"
When I add something that is not current in the recordsource for the combo I still get the msg box:
"is not on the list, Do you want to add it? click yes or no.
I click yes and then I now get this error:
"The text you entered isn't an item in the list. Select an item from the list or enter text that matches one of the listed items"
As I said earlier the NotOnListEvent worked just great until I added the AfterUpdate Event. Any suggestions for me? Thanks in advance
The Source Table is updating but the Table the Form populates is not updating.
Please help. This is driving me crazy. and thanks!

I have a form that runs a macro that refreshes by doing
Goto Record Next
Goto Record Previous
which generally works fine. But if I change combo box values a few times I get the following error message (titled "Write Conflict"):
Is this a refresh issue, or should I be looking for something else?

I'm currently running a replicated database in Access 2003 (plan on migrating to 2010; but have several users on 2003). I guess I pushed the number a fields within a table to be close to the 255 max and of course had a conflict in that table which put me over the top. Now if I receive the following error: "Cannot add a new column to conflict table 'Table_conflict'. Delete obsolete columns and compat the database."Since this will occur with all of my replicas is there a way do either automatically clear the data in the 'Table_conflict' or remove the table?

If, on the startup form of the attached mdb, you type anything in any of the text boxes of the FPersonale subform(which, in form view, is labeled "Shift schedule") you get a message titled "Write Conflict" saying that during the current session the record had been modified by another user, asking to choose between saving the record, copying the edits to the clipboard or discarding the edits.
I've tried to get rid of the message by putting Me.Requery at the end of the text boxes' AfterUpdate event code but the message still pops up.

Hi everyone,
I am doing some work on my company's database. It is a MS Access 2003 front-end with an SQL back-end.
Recently, I have asked the database administrator to add some new fields to an existing table and two of them are yes/no fields. When I have tried to update these fields, it comes up with a 'Write Conflict' error message and I can only choose 'Copy to clipboard' or 'Drop changes'. But either way, my changes do not get saved.
I have found that the error occurs when I refresh the table links to add the new fields and then try to save over just the old fields and not even trying to add anything into the new fields. Two of the fields are yes/no but they have a default value of 0 and I'm not sure what is causing my error. I read that it may be due to these yes/no fields having no default values so I thought I would mention it incase anyone may have suggested that to be the reason for my error message.
Any help is appreciated.
Thanks.
Gareth.

I have a problem with write conflict error. The database is functioning normally and without any problems but on particular computer. the systems are same (windows 7) with office 2010.I have a form with subform based on query. Changing the records in a subform is without any problems, but on one particular computar, I am allways receiving Write conflict error message. When I copy / paste the database from the wrong computer to another one, everything is OK. When I copy / paste it back to problematic computer, the problem is back also.It seems, that the problem is maybe somewhere in settings of this computer.

I have a form for updating contact details of customers/suppliers. Upon clicking an edit button the user can update txt boxes (as opposed to updating the table data directly and making a mistake). When they press save the below code runs:
Code:
If Not IsNull(Me.txtp_fname.Value) Then
Dim strFirstName As String
strFirstName = Me.txtp_fname
Dim FirstName As String
FirstName = Replace(strFirstName, "'", "''")
End If
