How To Set Up A Unique Number?

Sep 30, 2007

Hi There,

I am setting up a basic Data Licence database. For each new record I enter I want a unique number to appear at the top of my form that can not be changed. I would like the number to be the date it is entered plus the auto number so, YYMMDD-(auto number) eg 071001-1. I'm sure it's something simple but I am only new to access.

Also while I'm here, on my form I have a Product field, how can I make it so I can enter in more then one product?

I would really appreciate any help!

Thank you,
Dane

Unique Number Will Not Create

Jan 17, 2007

Hello i want to create a tracking number based on information entered into a form.

So i have my main table called "MainData" and this is in the backend and linked through to the front end where my form is.

I then have a query which is called "calllog" which has a field called "Call Number" inwhich i placed the following

=Year([Date]) & Left([CustomerName],3) & Right([Date Created],2)

This then gives me a unique number. Once i have entered a job in it will generate a number. Now this part works fine but it does not update the Maindata. How can i get the this to transfer the data to the maindata table???

Need To Have A Unique Number Across Several Different Tables

Jul 21, 2006

Ok,
Bacically I have 2 different lists (well there will be 7 in total):
tblValves
ValveID
KKS_no
Description
List - specifies thats its in the valves list
TOP_Code

tblSpools (pipe sections)
SpoolID
SpoolTagNo
Description
List - specifies thats its in the spools list
TOP_Code

The reason that I have kept these two in different tables rather than combining them is because the spools table will relate to a few tables that will have nothing to do with valves. For instance the spools table will relate to a table called tblPipeSupports.

The thing is this: I would like if there was a unique number across both tables. Collectively the items in coth tables are called components. Some of the components from either table will have drawing numbers for instance so I would like if I could have a table:
tblDrawings
DrawingID
DrawingTitle
ComponentID (FK to valveID or spoolID)

However this won't work because valveID or SpoolID could have the same numbers. I could use a composit key like SpoolID + List but I think I'm probally making it more complicated than necessary. Also I'll have several tables like the drawing table e.g. some of the components will belong in the testPack table... And I'l have to repeat that List field in each..

So what do I do?

Reports :: How To Make Unique Invoice Number

Dec 24, 2014

I am selling some products, namely A to M. I record the orders of costumers in a table, named "orders". For example, if costumer "Jack" has ordered as the following:

Code:
ID costumer product quantity unitprice orderdate

12 jack A 4 10 25/11/2014
13 jack B 5 5 25/11/2014
14 jack C 1 4 25/11/2014
15 jack F 3 2 25/11/2014
16 Jack G 4 8 25/11/2014
17 Jack H 1 7 25/11/2014

Then I make a report based on the above table and issue that as the invoice to the costumer, who is jack here.

How can I make a unique invoice number, which automatically increases sequentially for each invoice? Do I need to add a new column to the table? I also need to be able to look for a specific invoice based on the number, or date.

Forms :: Create Automatic Unique Number?

Apr 12, 2013

I am trying to create an automatic unique 'number' (actually text) in a form. Here is an example of the format...

1456.R1
1456 is the project number
R stands for revision
1 is the first revision

So, in this database there could be 1456.R2 etc. but there could also be other project numbers, say 2323.R1, 2323. Looking for expression I need to enter to have Access look up the last revision for a specific project and then add 1 to it?

Tables :: Creating A Unique Invoicing Number?

Aug 19, 2013

What I have is a small POS system I'm trying to create a unique invoice number for each transaction (multiple records)

I have two tables, one named "CurrentTransactions" and one named "Past Transactions".

I have everything working except the invoice number my system works by adding pre defined records into the table "CurrentTransactions" and once the sale has been finalised it transfers the data to the "PastTransactions" table.

take the last number from the "PastTransactions"."InvoiceNumber" to create an invoice number in the "CurrentTransactions", and I want to be able to do it using an expression in the default value property as opposed to in the form ( I've tried the form way but using Dmax would require me to almost rebuild my entire POS system )

Unique Number To Identify Each New Record Created

Sep 23, 2011

Example 1:

2011-1
.......
2011-3893 etc.

Currently I have an Access form which produces a new unique number to identify each new record created. To do this I use the unique ID autonumber from a table to identify the new records. I would like to change from this simple number to the the above format per example 1. The four digits to the left of the hyphen would always be the current year and digits to the right of the hyphen would be the unique auto incrementing numbers such as from my table. I need the year to auto increment by 1 each September 30th (new business year) and I need the numbers to the right to auto reset to 1 to start uniquely identifying records again for the new incremented year. As each record is closed I need the number to be written as a single entity in the new format to my database.

Example 2: After September 30th.

2012-1
.......
2012-447 etc.

Queries :: Adding Sequence Number To Transactions Based On Date And Unique ID

Jul 29, 2014

I have a set of transactions with a Unique ID field and a date. I want to add a field based that gives me the sequence of events for each Unique ID in order of when it happened.

For example, if customer X has 6 transactions, the sequence field would have a number (1-6) in each record that corresponds to the order in which those transactions occurred. The first transaction would have the number 1, the second would have the number 2 and so on.

Queries :: Adding Sequential Numbers To Generate A Unique Reference Number

Oct 5, 2013

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

General :: Creating Unique Sequential / Reference Number Every Time Report Is Printed

Feb 15, 2013

I have a rental database and I print several contacts for leases etc. what I want to do is have a unique reference number or something inserted to the report every time that it's printed. What I am trying to achieve is to keep track of which tenant corresponds to the report (Lease) printed by using reference number.

There is a seperate form which holds the tenants details and I would like to have a field on that form which would show the same reference number as the report so I can track which report was printed for who.

Whats the best/easiest way to accomplish this?

Modules & VBA :: Create Unique Reference Number Based On Field Values For Record

Jun 18, 2015

I want Access to automatically generate a reference number for a record based on the values in on two other fields for a given record using a form.

The first field is called Operation Number.

The second is Bag Number.

The reference number needs to be in this format: 19C.3.1

Where 19C is the Operation Number, 3 is the bag number, and 1 is automatically generated. Additionally I need the last number --the automatically generated one--to go back to 1 if with each new bag number.

This is kind of like library catalog numbers. Not sure how to do this.

General :: Creating Unique Ordered Number Field With Auto Shifting Values

May 31, 2013

I'm creating a database using existing data from an excel file full of contact details. What I need to add is a queue type system where each contact in the database has a "Place in Queue" number which is unique obviously.

Lets say Alan is number 1, Bob is 2 and Chris is 3. They have these corresponding numbers in the queue field for their entries.

Now what I need to have, through use of a form, is a way of changing Chris from number 3 in the queue to number 1 and thus have Alan automatically shift down to number 2 and Bob to 3.

Modules & VBA :: Get Number Of Unique Values Without Separating Values That Belong To Same Block?

Dec 5, 2014

I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?

So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.

If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.

For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.

So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.

There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.

A few notes.

1.Getting as close as possible to the requested number is a requirement.

2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).

my table (NR_PVO_120)
Row OtherID Fax
1 11098554 2063504752
2 56200936 2080906666
3 11098554 7182160901
4 25138850 7182160901
5 56148974 7182232046
6 56530104 7182234134

[code]....

A few sample outputs

one solution is taking rows 1-6 and 26.

OtherID
11098554
56200936
25138850
56148974
56530104
56148975

Another solution is taking rows 1-4 and 10-14.

OtherID
11098554
56200936
25138850
56024315
56115247
56148974

This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.

Queries :: Find A Way For Access To Find Unique Dates And Unique Names?

Aug 1, 2014

I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:

Start Date/Time
End Date/Time
Employee

At the moment this is what the format of my report looks like (I removed other unnecessary fields):

StartTime----------EndTime---------------Employee
12/06/2014 01:00--12/06/2014 03:00------John Smith
12/06/2014 04:00--12/06/2014 06:00------Jane Doe
13/06/2014 02:00--13/06/2014 05:00------John Smith
13/06/2014 08:00--13/06/2014 08:00------Jane Doe

I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?

Forms :: Auto Generate File Number Based On Number Of Records In Year

Jan 21, 2014

I have a form [IUDATA]

I have a add record button.

I have a date field [DATEIN]

I have a text field [DRPNO]

If the [DPRNO] field is empty, I would like the user to have the [DPRNO] field be automatically populated after the user enters a date.

I'd like the format of [DPRNO] to be "dpr YY-XXX"

Where:
YY is the year of the [DATEIN] field and
XXX is number of records in that year.

So for example, if it was the 4th record with a 2013 date the [DPRNO] would be dpr 13-004.

Tables :: Consecutively Number Table Rows With User Determined Start Number

Jul 13, 2014

I have an Access2007/SQL Server 2012 system with 20 users for an insurance company. The company does most of its business via a network of vehicle dealers around the country. If someone comes in to buy a motorcycle, boat, or recreational vehicle at a dealership they need insurance to take it home, and our dealers send the quotes to us.

The dealers, in turn, receive payment from us each month for their efforts. Some are paid a % commission on the premium, some are paid for each quote they send regardless of whether the policy actually sells or not, and some are paid a set amount per sold policy. (Yes, that is relevant information!)

We already have reports that tally the amounts due each dealer based on their payment scheme, but last month our bookkeeper had to write about 650 checks manually because the check writing is not automated. She'd look at the report, and then enter name, address, and amount (in digits and words) into Quick Books and print the checks from there, a horribly tedious process. I've been asked to print the checks from Access. Basically one click would print all 650 checks.

I've opted to use a Make Table query to move the commissioned dealers amounts to a single location, and then to run two append queries to add the records from those paid per quote and those paid per policy. At the end of the day, one table contains all the information necessary to print the checks...except one.

The check number.

I need a way to sequentially number each record in the new table with a user generated starting point, the first check number.

By the way, the check blanks are on standard letter sized paper, three to a page, with tear-off perforations to separate them, in case that information has any relevance.

I think the best way to accomplish this is from the report itself. I've created a blank field on each record for the check number, and what seems most logical is that the sequential number is generated on print and written back to the table, rather than just generating all the numbers at once. That way, should print ever be interrupted, it will be easy to take up where we left off.

Number Fields In Text To Number Field, Formula For Fiscal Year

Nov 26, 2004

Date of Birth (DOB) field etc. in one program are text - how do I make another file with the same data into number fields for Date of Birth field etc? When I copy data to file that has number fields the 09252004 is changed to 9252004. Can I get reports with the correct Date of Birth in them by moving data from text file to number file?

There is data entered monthly in file and formula has been set up for January, February etc as ---quarter: Int(([month]-1)/3)+1. I would like formula for the fiscal year for April to be counted as month 1, May - month 2, June as month 3, July as month 4, August as month 5, Sept as month 6, October as month 7, Nov as month 8, Dec as month 9, Jan as month 10, Feb as month 11 and March as month 12.

Reports :: Generate Number Of Rows In Report Depending On Number In Another Field

Nov 4, 2013

I have a form where we fill in information for supply of equipment 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 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.

Auto Increasing A Number, Depending On Maximum Number When Condition Is Met

Sep 18, 2006

Hi,

I'm trying to get the maximum number in a table field to increase it by one depending on the member that is selected in a drop down in a field.

I have three tables: members, programs and times. Each member can have N programs and each program can be broadcast N times.

Each member has a three digit code, like XXX. Each program has the three digit code of the member + three numbers that are supposed to auto increment. That is, the first program of member X with the member code XXX is called XXX001.

What I'm trying to do is that when a new program is filled in and I select the member, then the program code should update automatically, adding one to the latest program by that member.

That is, if the last program by member X that was inserted in the database is XXX010, then if a new program is inserted it should automatically be XXX011, even though programs by other members have been added in between.

This is the code I use now, for the AfterUpdate when selecting the member in a dropdown in the form. But although I've played around a bit, I just get error messages...

Private Sub medlemsruta_AfterUpdate()
Dim medlemskod
medlemskod = Me![medlemsruta].Column(2)

Dim strMax As String

strMax = DMax("programs_kod", "table_programs", "Left$(programs_kod, 3) = medlemskod")
Me!program_kod = Left$(strMax, 3) & Format$(Val(Right$(strMax, 3)) + 1, "000")
End Sub

Medlemsruta is a dropdown where one selects the member from the members table, where the three digit code is in the third column (Column(2)).

I'm trying to use DMax to get the maximum number for the particular member and after that adding 1 to that for the new program code.

Grateful for any advice! Thanks!
