Modules & VBA :: Adding Additional Sequential Number To Avoid Duplicate Value
Jun 10, 2013
I am not sure if it is possible to implement this but I would like your input. We get request from client via a web based form which contains a unique ID number called RDEFNumber. When we process the request internally, we use this number to identify the request throughout the process. The request from client contains processing of multiple files which are transmitted to us in different times of the day or days.
Every time we receive a file, an email is sent to the IT team with all the information about the file. We use an internal database to send the email to the IT team and use the RDEFNumber as the identifier in the subject line. What I am trying to do is to add an additional number at the end of the RDEFNumber automatically to differentiate the subject line.
For example, we take "1791" as a RDEFNumber. For the first time we enter 1791 to the database RDEFNumber field, it should check the table "tblRDEF" (record source) for duplicate value. If no Duplicate exists, it should keep the number as same. When we get the next file for processing with the same 1791 number and enter this number in the RDEFNumber field, it should automatically change it to "1791-1" since "1791" already exists in the database. When we get the next file, the number should change to "1791-2" and then "1791-3" and on.

Basically what I have is a database for tracking/logging parcels that arrive to the office. I want to be able to generate a reference number based on the date of arrival: i.e. the reference number should be ddmmyy### where ### is a sequential number. I know that I could just use the primary key's autonumber, for the sequential number but if I do this then the sequence will not restart at 1 on each date and because we receive a lot of parcels the reference number will grow to be too big to print out on the collection slips in just a few months.
two tables (one with the date and staff on duty that day and the other with the parcel's info') with a one to many relationship
I also have a query (Named: FullLog) that picks up the following data from the tables:
Name - Description - Size - TrackingInfo' - Staff - DateReceived - Count
The field named Count is a DCount function that I used to find out the number of times each date is repeated. This is the Expression that I used:
Count: DCount("*","FullLog","DateReceived = " & [DateReceived]) [Note that DateReceived is first converted into a string using CStr()]
This is as far as I have been able to get, I have been looking for weeks for a solution to this problem but I have yet to find one. I don't even know if the DCount function is the correct way of doing it, I did read somewhere that this produces a very slow query.
Effectively what I want to be able to get is something of that resembles the following
DateReceived - ReferenceNo
051013 051013001
051013 051013002
051013 051013003
061013 061013001
061013 061013002
071013 071013001
071013 071013002
071013 071013003
071013 071013004
071013 071013005
081013 081013001
081013 081013002
091013 091013001
101013 101013001

I have a form where we fill in information for supply of PPE to employees.
Each item must be signed for on a printed report.
I am encountering problems trying to create enough rows in my report detail for each signature of the number of items supplied.
For example, on the form I will select the "equipment" - 4 hats supplied and 3 boots. On the report I want the equipment set as the group and the detail to be a number or rows which equals the number of selected items. therefore under the Hats group heading I want 4 blank rows which are made up of 3 text boxes - Print Name, Signature & Date and another group heading for boots but with 3 lines.
The Query gives the results below: (Item name is linked to a PPE table containing Item ID, Item Name, Cost etc..)
IssueIDDateProvidedItem_Name AmountIssued
0001 01/11/2013 Gloves (Orange) 10
0001 01/11/2013 Hard Hats (Black) 2
0002 02/11/2013 Hi Viz (Large) 5
The report I aim to generate from this should look as attached ...
The query/report is set up as a parameter report so I will enter the issueID such as 0001 and only those items will appear on the report to print and sign.

Currently if an employee attends a mandatory training session the details are entered individually into in a single table which contains all the employees' attendances to training, this is achieved via a bound form.
Works Fine.
My question is, if the training is carried out by a number of employees can this attendance be recorded on one form and assigned to each of the employees who attended?
Using Access 2003

I have inherited a 5 table database which is associated with membership details and all tables are linked via the membership number which appears in every table..eg
Main Register
membernumber, surname, forename, age etc etc etc
Home address
membernumber, address1, address2, address3, postcode
Business address
membernumber, company name, address1, address2,etc etc etc
Subscription
membernumber, grade, subscription, bank account, etc etc
Training
membernumber, college, results, etc etc
I am informed that it is bad practice to have duplicate data in multiple tables (ie. membernumber field) as updating the data item would be difficult (eg. if the members number needed to be changed for any reason). If this is the case how would I restructure the tables but maintain the link through the membernumber?
I am fairly new to Access....as you can no doubt tell.

I have a report which has say two columns - staff number and visit date. For a staff number (which is unique) there may be more than one visit date. But I want to list a staff number only once and not multiple times in the column (but want all the visit dates of course). How can I do that?

What I am trying to create is a Despatch database for our warehouse.
Records in table:
Date ()
Customer
Invoice #
Qty of parcels sent
Courier used
consignment number
In most cases we will send one invoice per consignment number (database works fine for this) But on occasion we may send multiple invoices. What I want to be able to do is have a list box to select the number of invoices, this will make available additional fields for Invoice # and Qty of parcels sent. The idea is to get away from keying in the other records for each invoice going to the same place.

Hi,
Just trying to figure out how I can run a select query on some data I have and how to also include an additional field which has a value counting the number of rows.... eg in the first row there would be the usual results and the new field would have a value of 10001, second row would be 10002, third would be 10003.
I've done some searches for sequential numbering but couldnt find anything so far.
Thanks, j

I have a code that works great from the parent form but I decided to change the format and call it from a lostfocus event in the subform instead. Now I keep getting error 3314:"You must enter a value in the tbGuests.LastName field".
The code should copy the parent form fields and create x number of duplicate records according to a field on sub-form. It then runs an append query to add the information from the subform.
Code:
Private Sub GuestsInParty_LostFocus()
Dim partymsg As Integer
Dim dbs As dao.Database, rst As dao.Recordset
Dim F As Form
Dim intHowMany As Integer
Dim intCounter As Integer
[code]....

Hello, I am very new to access and I am trying to create a simple sytem to help us create part numbers. We are using a 2 digit descriptor to help define the part some. Then we want to add a sequential 7 digit number on to that.
Example:
01 (is electrical)
02 (Shop supplies)
etc....
So...
01-0000001 would be a part number for an electrical part.
I do not understand how to have access add the zeros to the front. I would also like to be able to jump a bit out of line to reserve part numbers for certain projects and also include some that we already have.
If this make any sense to anyone, any help would be appreciated!
Thanks,
james

I have an Access table with records that have a two letter, two number alphanumeric identifier (AA01, AA02 etc)
I am trying to create a form whereby, when the user types in the first two letters, the next sequential number from the table is generated.
The letters can be totally random and selected by the user, but the numbers do need to be sequential.

I have a form on which I need to print a sequential number - increasing by 1 each time the form is printed. I cannot think of a way to do that - perhaps something returned from a query? Any suggestions?

I've tried using DMax codes shared by the generous members of this group. But i can't get the results i needed. :-(
My table consists of the following fields:
ColID - PK
PolID - FK
AmountPaid
ORDate
ORNo
I added another field which i named "ColNo" - this field should assign a sequential number to a new payment record for a specific PolID.
My table looks like this:
ColID PolID AmountPaid ORDate
11125 123 2,000 10-Sep-06
11126 123 2,000 10-Oct-06
11127 123 2,000 10-Nov-06
11128 456 1,000 8-Aug-06
11129 456 1,000 8-Sep-06
11130 789 4,000 21-Aug-06
Again, my idea is to create a sequential number for the ColNo field:
ColID PolID AmountPaid ORDate ColNo
11125 123 2,000 10-Sep-06 1
11126 123 2,000 10-Oct-06 2
11127 123 2,000 10-Nov-06 3
11128 456 1,000 8-Aug-06 1
11129 456 1,000 8-Sep-06 2
11130 789 4,000 21-Aug-06 1
I placed the code Nz{DMax("field name","table name"),0)+1 on the control source of the ColNo field and i also tried copying numerous similar codes to the BeforeInsert, OnCurrent, etc.. events, but the result is ALWAYS THE NEXT MAXIMUM NUMBERFOR THE "ENTIRE" POLID.
What i mean is, if i enter a new record, it would give me a sequential number of "4". I figured out this is because 3 is the last maximum number as i have shown on my sample table. Even if i use the PolID "789", the number shown on the ColNo field results to "4".
IT SHOULD HAVE BEEN "2". Considering that the last ColNo used for PolID 456 was "1".
Hope someone could help me on this..
Thanks!
Sheila

Dear All,
I know that there may have been many posts on this and I have searched for a total of about 2 hours in these forums before posting, so please don't shoot me down for asking this.
I simply need to know how I can create a unique, alphanumeric order number. I was going to use Autonumber, but from what I have read on these forums, that is not the way to go, as Autonumber is simply to identify the record.
What I need is an number like so: ST000. It needs to start at ST142 and increase by one each time. Obviously I would like to avoid gaps from records being deleted or not completed etc.....
I really have no clue how to do this, and would appreciate it if anyone can point me to a post that would help, or offer me the solution.
Thanks,

I have a table like the one below. I need to Auto Sequence based on JobIDOne in the field that says sequence in the manner that I've typed. Hand typing is not an option because by table will be updated regularly. All other fields are updated via a form. I need a either a macro or VBA solution that can reconcile this, preferably through the table. Note, I do not want to use a query to create this sequencing or SQL language as I do not know how to write SQL commands.
I know it can be done but I've seen about a thousand ways to do it that I haven't been able to modify for my specific table.
DateOne

I've received a database that is a digitized population register from the 19th century. All adults have been entered into the database, but all children are missing.
Every person has a unique number that corresponds with the original source (this variable is called 'no', this is not the autonumber primary key thing). Instead of searching in the original source which numbers are still missing, I would like to add the missing numbers (with no additional information, because I still need to type that in).
For example, the table now looks like this:
no - name_last - name_first - occupation etc
1 Smith Henry baker
2 Smith Mary
5 Williams John butcher
6 and so on
So 3 and 4 are missing.
How can I add these missing numbers automatically?

We have a large database table [PRODUCT] with the following fields PROPNUM and P_Date and GAS. We need to normalize the GAS field to the first month of production based on P_Date and sequential months following to average the data. We believe the easiest way is to create a sequential number for each Key PROPNUM that represents the first month of GAS the second month of GAS etc.
We have followed several of the posts on how to sequentially number records, but are struggling to get them to work.The latest effort was to use the make a table query creating an expression with the following.
DCount("*","PRODUCT","[PROPNUM]=" & [PROPNUM] & " AND[P_DATE]<=#" & Format([P_DATE],"mm/dd/yyyy") & "#")

I have a table called External Audit.
I want each record to get a unique sequential number on the basis of Type of Audit.
Type of Audit column has 3 options OB, INR, MINR to choose from
If i select type as OB then the notification number should start from 1 and carry on numbering it whenever I select the same value.
When I select different type eg: INR then it should again start number on the basis of type. INR1 INR2, INR3 etc.
Is sequential number is the right word to use for this function ?

How can I prevent duplicate records from being added from a form, the dcount in the text field property, trigged before update is where this should be used is what I know but having trouble with the syntax.
I've got the table tblInvnetoryDetail with InvID(AutoNumber), and SerialNumber. The form text field is txtSerialNumber. I've managed this far with the expression
DCount([InvID],"tblinventoryDetail","[txtSerialNumber]=&"'") but this did not work.
How can I get the expression to avoid duplicates.

I have created a form using all these fields..Now what i want to do is I want to create custom order no as first 2 digit of accounting year+Series+Autonumber of respective series as
14R-1
14R-2
14Y-1
14Y-2
14Y-3
14B-1
15R-1
15R-2
15Y-1
