How do I get access to auto fill a text (supplier)? I realize that for a new supplier I would have to input the supplier name, however my question is what should I do for Access to enable auto-fill so that the next time I have to input that supplier it would auto fill for me. This is happening in a single column.
For example: In the supplier column, I typed Dell in the first row, Apple in the second row, HP in the third row. Now when I start typing 'Apple' in the fourth row, I want it to autofill 'Apple' because I have already input that once.

I need to know how to auto enter the date of the previous record into a new record. I have this db for my vehicle log sheets and I submit monthly a claim for the business km from my company. I usually cant remember the date of the previous claim and have to scroll back until I find the field with a date. It will be useful if the date was copied into every new record until I edit the date when I submit the claim. What I ask is during the new month all the dates will be the same until I submit the claim. I do not know how to do this, and yes I have done a search.

My situation is this. I have 3 tables that I have imported from my mainframe system, between these 3 tables I have the data of product code, description,supplier code, supplier name, order method, and ABC code.
I am trying to create another table that I can capture daily Out Of Stock data for products.
What I would like to do is to enter the product number in the first field of my new table, and then the remaining fields will auto populate with the correct details based on the product data stored in the parent tables that I have imported.
How can this be done?

I need to create a production forecast form based on previous sales history.The history is based a sales and grouped by month & year
So on the form, which needs to be a continuous form, I want products to show as rows and months as columns The sales history per month needs to be displayed as well as a field allowing to user to enter the production forecast.
I can write the sales history to a temp table.However I never know how many months history the user is going to want displayed at run time. Could be 3, 7, 12 or 15!
Attached spreadsheet shows what I am trying to achieve. Is this possible and if yes, how would I do it?

I need a way to dynamically store a particular value in "field_2" of the CURRENT record depending on whether or not the value of "field_1" of the CURRENT record is identical to the value of "field_1" of the PREVIOUS record within the same table. The table is sorted on "field_1".
So, if the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is also "ABC", then store a value of "PPP" in "field_2" of the current record. IF on the other hand, the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is "XYZ", then store a value of "WWW" in "field_2" of the current record.
I have a report that will use these results to count only the number of records that have a "WWW" in "field_2".
Is this doable, maybe in a query somehow?
I should add that whatever the solution, it needs to be compatible with Access 2000.

For a project i'm working on i'm manually entering e-mail addresses, names, and surnames. I would like a username and password automatically generated based on what the corresponding fields' first name and surname is with formatting.
Example:
Is there any way i can do this using input masks and validation rules? Would this require a VBA script?

I wanted to auto populate an invoice record with same values as previously ordered by that same customer. I don't want to use default values as every customer orders different things.
BUT almost all customers make REPEAT orders of exactly the same things they ordered previously.
So...for example, can I search the invoice records by customer ID/Name and copy all the data from their previous into a new invoice record. I guess I could do this with an append query?
But will an append query run when I just click on 'new record' in the invoice form? Maybe there is a property '.on new record'...open append query....?

I have a table with the following fields; Row; AnimalID; Weight: Date_Weighed (see attached screenshot example).
I would like to make a query that gives me the percentage weight loss/gain since the last time a particular animal was weighed. For example, animal AAA gained 100% between 2014/01/01 and 2014/02/01. Animal CCC gained 0% between 2014/02/01 and 2014/03/01.
I plan to use this to create a pop-up that informs me if an animal had lost over 15% of its bodyweight since the last time it was weighed, indicating either a loss of body condition, or that a female has given birth.

I am trying to create a query which will return records which are from a specific month of the previous year...
To better explain:
If I have sales from 2013 and 2014 in Jan, I want a query which will show me the results from Jan in 2013 only... I'm just unsure on how to make a query do this and it's probably really simple.
But then in 2015 I will want it to show results from 2014 without having to change the expression or criteria.

I'm trying to update an imported table from an excel spreadsheet with missing details. The table's records are in order so I just need to fill in a blank field with data based on the previous one as shown.
ID Name Location
1 Bob London
2 Larry
3 Harry
4 Jerry Glasgow
5 Paul
6 John Southampton
I need to fill in the location blanks simply with the last location details, so records 2 and 3 with London and 5 with Glasgow. Is this easily done or would I need to pull all the data into an array and work on it there?
I've tried searching for an answer but haven't had any luck.

Hi everyone,
I have two combo boxes on the same form bound to a table. I want the contents of the next combo box to change based on the previous combo selection e.g
cboContinent cboCountry
Africa Zambia
Africa Congo
Africa South africa
Europe England
Europe Holland
If I choose Africa in cboContinent, I want to see only Zambia, South Africa and Congo under cboCountry and if I choose Europe I want to see only England and Holland
Thanks
Humphrey

I'm having trouble with a tricky conditional format in a continuous subform.
The criteria is based on field [GroupNo] when it changes (increases) which are always listed in numerical order.
Basically all I want to is for the text box colour to alterante (eg blue & yellow)when GroupNo changes value
So it would look something like this....
Group NoID (highlight colour)
1 (yellow)
1 (yellow)
1 (yellow)
2 (blue)
2 (blue)
2 (blue)
3 (yellow)
3 (yellow)
etc etc
btw, although values will always be in order they may not all be output, so it's not just case of odd, even, odd, even (that would be too easy!)
I can retrieve the Previous Record's GroupNo value (via a function) in another text box and compare current GroupNoID with this in the Format Expressions and manage to change the colour, but it won't sustain this new colour for the subsequent same GroupNos, obviously as the values have changed.
So how can I....
Change the colour when the value changes.
Keep this new colour until it the value changes (increases) again.
Many Thanks

I am trying to write some vba code to auto fill a cell's value based on the value of the cell in the previous record (In a datasheet form) i.e. if the value in record one was '1' and the down-arrow key was pressed then the value '2' should be entered into the new ext record
I have written some pseudo-code to show what I am trying to accomplish:
if keydown = down-arrow and current cell contents isnumeric then
Cval = current cell contents
if current record = last record then
create new record
move down 1 record
set cell value of new record to cval+1
else
move down 1 record
if cell value = null then set cell value of record to cval+1
end if
end if

I am creating a database for an annual golf tournament. Part of this is to allocate players to play off together at certain times.
I have a form bound to a table called tblteeofftimes. This form has five fields (continuous form) - four of which are comboboxes whereby user selects each player for the record (who will play together). The other textbox has the tee off time. the first tee off time will be allocated by user eg 7:00 am.
My problem is I need to update each ensuing record with a new time slot at 7 minute intervals. Rather than have the user populate the form themselves I would prefer this be done authomatically as the user moves onto the next record.

I have a table called Contacts in Access:
ID Email
001 email1
002 email2
003 email3
004 email4
008 email5
010 email6
And I have a table called Data in Access:
ID Date Person Title Yes/No Action
001 20/4 Mr A Consultant
001 20/4 Mr B Supervisor
001 20/4 Mr C Consultant
004 20/4 Mr D Consultant
010 20/4 Mr E Consultant
010 20/4 Mr F Supervisor
What I'm looking for is coding that would start with the first ID number in CONTACTS and see if there is the corresponding ID in DATA. If there is, then I want it to create an Outlook email and have:
1.To field populated with the email address in the CONTACTS table
2.From and CC fields to be my email address
3.The subject line needs to read [ID] "Request" and then today's date backward (e.g. 20150420).
4.The body I need to put some generic wording and then a table with the records from the DATA table (first 5 fields plus the headings).
5. The format of the table etc isn't important as long as it is a table format
If it's created the email I want it to go back to the DATA table and put "Email Created" in the Action column for those IDs.
I don't want the email to automatically send; I only want it to create a draft (as this data needs to be manually confirmed before sending).
If for example it gets to checking in DATA table for ID 002 (and as seen there's none there), I want it to skip creating the email and move on to the next ID.
In the end I would expect to see 3 draft emails open in Outlook ready to be sent, looking something like the below (just 001 below)?
From... my email
To... Email1
CC... my email
Subject: 001 Request 20150420
action the below:
ID Date Person Title Yes/No
001 20/4 Mr A Consultant
001 20/4 Mr B Supervisor
001 20/4 Mr C Consultant
And the DATA table look like this (if only 001 email was created):
ID Date Person Title Yes/No Action
001 20/4 Mr A Consultant Email created
001 20/4 Mr B Supervisor Email created
001 20/4 Mr C Consultant Email created
004 20/4 Mr D Consultant
010 20/4 Mr E Consultant
010 20/4 Mr F Supervisor
I will need to add more data to the CONTACTS table over time, also the DATA table will be different each day so I need the coding to accomodate for both of these possibilities.

There is a form which the user fills in 8 fields and saves it. Once saved, a new record opens.
However, I want to modify the save button to save the previous record and display a new record with only a limited no of fields to display from previous record, say 4 fields display from previous record, and the user fills the remaining 4 and saves it. Thus, the save cmd should continue to display 4 fields from the previous record.Already tried below code for save button but it displays all data of previous record as it is, doesn't display blank space for combo.118 and text2
DoCmd.GoToRecord , , acNewRec
DoCmd.GoToRecord , , acPrevious
Combo118.Text = ""
text2.Text=""

I need to make Access automatically create new records in a table for me.
Just for example:-
Table #1 has 2 fields
PersonID (autonumber)
PersonData (text)
Table #2 has 3 fields
ID (autonumber)
PersonID (number)
MoreData (text)
The database user creates a new record in Table #1 using a form.
I need the database to automatically create a field in Table #2 and fill in PersonID, taking the value from the autonumber field of the same name in Table #1.
The MoreData field can be left blank. I don't need that filled in automatically. I just need a new record to be created automatically in table2 with the PersonID field filled in with the most recently created autonumber.
Help massively appreciated.

I have a table full of meter readings. I want to have a field called consumption which looks at the reading just entered for that month and then subtracts the previous months reading for that meter which leaves the consumption.
Can I get a formula that can work this out automatically?

I'm struggling with a query to evaluate current and prior record data. I have a query producing 5000 records. I need to group records by Case ID and compare current date record to previous date record to determine if a team and worker name has changed during the year. I need to count how many times a cases is transferred to and out of a particular team from the beggining of the year. i.e., On 1/1/2014-Team1 has an inventory of 500 cases.
During the month 25 cases are transferred into Team1 and 15 cases are transferred out of Team1. So on 2/1/2014 Team1 begins with an inventory of 510 cases. Throughout the year cases come and go from and to Team1 each month so need to figure out how to create a query to count each change. See attachment displaying how the data is listed and how I invision it to work with the In/out column counts.
Specifically, at the begginig of the year (1/1/14) for case ID 1003 you can see it belongs to Mary in Team1 for January and February. Then in March the case is transferred out and went to Joe in Team 3. So for Mary a "-1" is recorded as a negative count for that Case ID. If later in the year the case is transferred back to Mary a "+1" would be recorded. Respectively evaluated for each of the 5000 records to get a total count for each of the teams by Case ID throughout the year.
I've started with DLookup, tried comparing current month to previous month using DMax. It works as long as I only select one case ID used in a separate query but if I use the whole subset (5000 records) it fails. I can't figure out how to group each set of case IDs and then apply the query.
My attempted query: DLookUp("[Team]","[Team_qry]","[Team_qry]![Date]=#" & CStr(DMax("[Date]","[Team_qry]","[Team_qry]![Date] <#" & CStr([Date]) & "#")) & "#")

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
