Forms :: DMax Criteria - Generating Sequential Number
Oct 11, 2013
I'm using the following code to generate a sequential number"
Code:
Private Sub Form_Load()
Me.txtReceivedDate = Now()
'assign an EmailID when form loads
Dim CurMax As Long
Dim NewMax As Long
'poll the current EmailIDs for the largest number from current year and add 1
[Code] ....
Until recently, I didn't have any criteria on the DMax and it worked perfectly. It's now been decided that the EmailID should reset back to 1 when the calendar year changes.*
*EmailID is not my primary key - There is a separate autonumber field used as the primary key.
The table I'm using the DMax on has a field named ReceivedDate which stores a Now() when a record is created. The form I'm working in has a textbox named txtReceivedDate that is set to Now() when the form loads as can be seen in the code above.
What I'm trying to use as my criteria in the DMax is to match the Year() of ReceivedDate in tblEmails to the Year() of txtReceivedDate on the form.
For 2013, the current max (CurMax) EmailID is 21. If I set my computers date back to 2012 (where the CurMax is 3) the txtEmailID is still being populated with 22, even though txtReceivedDate shows a 2012 date.
I've tried a handful of permutations of the criteria string:
I've tried a few others long the way that I don't even remember, but there's probably little value in listing all the ways that don't work.
I've got a syntax issue within the criteria since it's the first time I've tried to use one and it contains a couple moving parts.
Once I get this sorted out a follow on question is about dealing with the users changing the txtReceivedDate to a different year. As of now, I have the same code (everything except "Me.txtReceivedDate = Now()") also present in txtReceivedDate_LostFocus(), but I'm not sure that's the best place for it.
Hello Access friends, Trying to have a sequential autonumber for the ScreenID with the DMax () function. Please advise on what is wrong with the following : =Nz(DMax("[ScreenID]","[Screenprep]","[ScreenID] = '" & [CarModel] & "-" & Left$([Category],1) & "'")+1,0) Neither putting this code in control source or beforeupdate event of the form is not working.
I have looked around and from previous posts in the forum come up with this module. But it is not working either: Public Function NewScreenID() As String
Dim db As DAO.Database Dim rst As DAO.Recordset Dim ScreenID As String Dim CarModel As String Dim Category As String
On Error GoTo Err_Execute
Set db = CurrentDb()
Set rst = CurrentDb.OpenRecordset("SELECT Max([Screenprep].[ScreenID]) AS MaxScreenID from [Screenprep];", dbOpenSnapshot)
If IsNull(rst!MaxScreenID) Then NewScreenID = [CarModel] & "-" & Left$([Category], 1) & Format(1, "0000") Else NewScreenID = rst!MaxScreenID + 1 End If
rst.Close Set rst = Nothing Set db = Nothing
NewScreenID = ScreenID
Exit Function
Err_Execute: 'An error occurred, return blank string NewScreenID = "" MsgBox "An error occurred while trying to determine the next sequential number to assign."
End Function
In advance thank you for your time.Can someone please guide me on how to sort this out?
I have a question concerning the automatically sequential numbering of a primary key as part of a composite primary key.
Tbl_treatment: ID=numeric field (also in tbl_pt and in tbl_tumor) Tumornr=numeric field (also in tbl_tumor) Treatmentnr=numeric field
[ID] and [tumornr] are fixed and i would like to automatically number [treatmentnr] per [ID] AND [tumornr] in a way that the output will look like this:
However, when i use the SQL-formula below my output looks like this. It seems as if the function is not properly taking the composite primary key of [ID] AND [tumornr] into account or not finding the true max value:
I am currently creating a form to input new return parts into a database. I am trying to automatically generate a tracking number (##-AA-####-####). I have gotten myself to generate the ##-AA-#### in a list box and almost was able to generate the sequence number, 0001, 0002, etc. using the dmax function. I would like to generate the sequence number one higher than the highest, depending on part type and last 4 digits of part number. Our parts have unique last 4 different p/n but more than one can fall under the same type.
I am using Ms Access 2007 and I am new to it..I have table of following fileds
ID (as a primary key)
AccountingYear (Filed for current accounting Year e.g., 14-15; 15-16)
Series (text- as R, Y, B etc to denote series code)
OrderNo (field to store custom autonumber Order No e.g., for Series R-1, R-2, for series Y Y-1, Y-2, etc)
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 15Y-2
Means autonumber starts with 1 for every accounting year of respective Series..how to do this and what code or formula should be applied and where the code should be inserted as I am new to Ms access
1. Which event occurs when anything changes on subform (Delete row , add row , perform the sort, Especially when you add a row to be inserted in the current sorting between the rows)
2. I have column sequential number that need updating when occurs any event on subform
3. "On current" is event that occurs always when changing rows in subform, how to process rows sequential (row by row) thru subform and update field that represent sequential number.
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!
Im trying to create a document register in Access 97 to create and track document numbers, for this i want to assign a 6 number unique id to each record starting at 000001 going up in order to 999999 which will form part of a unique docuement number ...i know this may be a really easy thing to do but can anyone tell me how?
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 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".
Hi, im pretty new to access, i need some help or a pointer on how to set up a sequential number. i have a orders table with an order number starting GO how to i get access to count up in ones from the starting number. regards
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.
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.

I have a small .mdb for invoicing. Till now I had to put invoice number, which had two parts, manually for the first part, for example 001 or 002 and automatically for the second part as Date part. So I had, for example 2006 or 2007. The complete number was, for example 001/2006 etc.
The problem was New Year. Now, all previous invoices from 2006 have 2007 extension and the first parts are not starting form 001 but they continue.
Hi, I'm trying to make a database where a Date and a Service Number is entered into a form.
I have 2 buttons, one to automatically enter the Current Date and the second to automatically enter the Service Number.
The service number is incrimented by 1 each time and reset for every day.
eg.
Date Service Number January 1, 2005 1 January 1, 2005 2 January 1, 2005 3 January 2, 2005 1 January 2, 2005 2 January 5, 2005 1 January 5, 2005 2
I already have the button that enters the Current Date. However, I am having trouble with the second button.
How can I code the button so that it searches the table for the Current Date and finds the record with the greatest service number for that date? After this is done, I want to create code that will automatically enter the next service number into the Service Number Textbox on the form.
eg. Using the Example Table Above The date January 5, 2005 is entered into the Date Text Box and the Search Next Service Number button is pressed. The number '3' should show up in the Service Number Textbox
Sorry if its hard to understand, but thanks anyways.
I just realized that I placed this in the wrong forum, Sorry for the inconvenience.
I am trying to create a sequential number field in a query. I cant use an auto number for the fact that i am combining multiple tables. Any help with this would be greatly appreciated.
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.
First off, can it be done? I'm using Microsoft Access 2007, I'm wanting to generate an auto-number on the report. Basically I have an OrderTable, a PartTable, and a PackingListTable. I have a report that shows all orders ready to be shipped. But I need the shipping report to have a packing list number. I want this number to be auto-generated, and I was hoping I could do this when the report is opened. Right now the report is generated through a query of orders that are ready to be shipped. Yet I can't figure out how to put an auto-generated packing number on the report.
I am trying to create an auto-sequential order number
Example : AB000112 - AB is standard prefix, ''0001'' is the first invoice number, ''12'' is the year 2012.
so the next order number should read AB000212 and the next AB000312
Out of this, I have to issue several debit notes relating to the same order number when the payments are due from customers over a period of time, this will be
I need some help here and any would be muchly apprieciated.
I am building a database for a theme park fast pass system where a customer can book themselves a place on a ride at three session times a day.
Now my problem is, that I need to generate a card number. 5555 1946 as the first 8 digits (this always stays the same) and then the last 8 digits is the customer ID number, which is in the same table. So there are 16 digits in total.
Let me give you an example:
A new customer registers and are assigned a customer ID of 1000 0001. Therefore the Card Number for that customer must be 5555 1946 1000 0001.
I have used auto number for customer ID so when a new customer signs up, there ID is 1 more that highest already in te database.
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.
When I create a new record I am also generating a new Auto Number. This is so I have a sure fire way of returning the records that I want to return. I have read where it is a known issue that when using the Compact and Repair it can reset the Auto Number to a lower number and generate a duplicate Auto Number. That is the problem that I have at this time. I have tried using the Allen code but it doesn't seem to worked on linked tables. I use linked tables because I have multiple users who can access this system at any given point in time.how to have the Auto Number field select a number that is unique
I am wondering if it is possible to calculate scores automatically based on the number of tick boxes the users have selected? If yes, how do I go about doing this feature?
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:
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
