Figuring A Start Date Based On End Date And Hours
Dec 27, 2006
I manage training for a large organization and am able to get a data dump that contains class end dates and class hours. Based off of those two, is it possible to determine a start date (excluding non-business days)?
For example, a 2 day class would be 16 'Hours' with an 'End Date' of Friday the 15th. Is there a formula that would give me Thursday the 14th as a 'Start Date?'
More importantly, if 'Hours' is 80 and the 'End Date' Friday the 15th, would it be able to give me a 'Start Date' of Monday the 4th? Can Access account for holidays?

I have attached a sample of a database.
Table 1 has all the items I am trying to sell with sell by date after which I cannot sell this item. Then in Table 2 I have forecasted sales. So now I am trying to calculate stock consumption to see if I will be left with any stock that I cannot sell.
So now somehow I need to deduct sales forecast from my stock holding but it needs to go by date i.e. consume all stock for Item 1 with date 16/09 before moving to Item 1 with sale by date 23/09.
So based on the attached example, I can see that on 16/09 I will consume only 5 cases from sell by date 16/09 and another sale is 18/09. So that would give me information that I will be left with 95 items dated 16/09, which I cannot sell because they will be out of date.
Ideally I would like also to include the logic that if Item is out of date it would move to the next sell by date.
So in this case sale of Item 1 forecasted for 18/09 (94) would consume the whole stock (50) with date 23/09 and another 44 from date 01/10
For Item 2 I can see that units with Sell by date 30/09 will be consumed on 25/09 and I will start taking stock from next sell by date which is 14/10.

I have a DB with Start Date (dd.mm.yyyy), End Date (dd.mm.yyyy) and Quarters. We have 4 Quarters (Jan-March, April-June, July-Sep, Oct-Dec) and extra columns of month (xxx) and year (yyyy) too.
The problem is the front end users have access permissions to modify the dates. if they change the start date and end date then they are manually gonna change other fields like quarter, month and year too (Which they don't want). The users don't need to manually update the column values for Quarter, Month and Year
For Example,
If the user modifies Start Date to: 22.05.2014 and End Date to: 24.06.2014 (then the quarter column should be fixed to 2nd quarter and month should be June and year should be 2014).
2nd Example: We need to consider the End Date for classifying the quarters, Month and Year
If the Start Date is: 22.05.2014 and End Date is: 24.12.2014 (then the quarter column should be fixed to 4th quarter and month should be December and year should be 2014).
The solution is when ever the front end user modifies the dates then automatically the quarter, month and year columns need to be changed.
Sample piece of Access data sheet with just 3 examples. Column names Start date, End date, Quarter, Month, Year.

I am having difficulty getting a second textbox to display the correct total of hours based on a date entered into a first textbox.
Setup:
Table Name: TestTable1
Fields: 'RequestDate' & 'Hours'
Form: 'Form1'
2 Textboxes Unbound: Named 'Date' & 'Total'
What I am trying to accomplish:
Based upon a date entered into the "Date" textbox I want the "Total" textbox to display the total hours associated with that date.
What I have tried:
I have tried using, in the control source property of the "Total" textbox, many iterations of both Sum(IIF & DSum(
I am currently using the following:
=DSum("[Hours]","TestTable1","[RequestDate]='Forms! Form1!'Me.Date'")
I have tried this without the Forms designation; without the "Me" designation; Etc.
Some attempts return the Error or Name error while other efforts return a blank textbox...

How to create a table that has a recurring entry, based on a start date and a nominal interval period of e.g. one calendar month?
Is it possible to have these entries applied automatically each time so that they appear, as required, when the table is opened?
For example, for the entry of regular payments due per month.

I've attached a stripped down version of a small order database I'm working on.
A user would enter an order, the amount and the date the order is required by.
As you can see from tbl_seasons, the business has financial periods that match the first and last 6 months of each year. Each season has a start date and end date.
What I'm trying to build are two queries:
1. A query which lists all orders and has an extra field which shows the "season_id" that the order (date) relates to (based one the start date and end date in tbl_seasons)
2. A totals query which shows the total order amounts by season
how I might build these 2 queries.

Right now I have this in the query criteria row:
>=[Enter Start Date:] And <=[Enter End Date:]
This makes two prompts pop up one at a time. I was wondering if there was a way to combine both start and end date boxes in one prompt so I can see what dates I decide to type side by side. Is this possible?

Hello.
I have this continous forms which gets data from a query. The query has a field that sums date(hours), and I want them to show more them 24, for example, 42:30.
If I use general number it shows something like 1.2303256 and if I use short date it show something like 02:00 for 26 hours.
If I use a simple code is shows the SAME value in ALL the continuos form.
Which code should I put at the forms field so it would work, that is, it shows a diferent short date in ALL the continous form?
Thanks

How would you make two prompt boxes which ask for the start and end date so you can select all the data between the two dates...
[Start Date?] And [End Date?]
E.g., 01/01/2006 And 07/01/2006
So I can select all the data between that week. I also need to use this for the remaining weeks in January and February. This is really simple...gah. Thanks guys.

Ok I have a tbl with the following fields:
Name
Date
Activity
Hours
I have a form with these fields on it and two additional fields:
Total Hours
Hours this Month
Those fields need to do just what they say, calculate the total hours and calculate total hours for the current month only.
Here is the code that I have thus far, that is not working:
SELECT tblVolunteers.Date, tblVolunteers.Name, Sum(tblVolunteers.Hours) AS tot
FROM tblVolunteers
GROUP BY tblVolunteers.Date, tblVolunteers.Name
HAVING (((tblVolunteers.Date)=Month(Now())))
ORDER BY tblVolunteers.Name;
If I take out the "=Month(Now)) portion I can get the total hours, so that part is done, I just figured that out..... I get nothing back on the above sql statement.
What am I missing?

I am trying to subtract 12 hours from a time-date field when the payperiod does not equal 01.
in a query I have:
work date: iif([payperiod]="01",[StartTime],[starttime]-#12:00:00#) - Access added a PM before the second hash so it looks like this:
iif([payperiod]="01",[StartTime],[starttime]-#12:00:00 PM#)
When I run the query I get a message box: "syntax error (missing operator) in query expression '00:00:PM#,2))". I am unable to open the query to correct the error. I can cop the unaltered query from a back up database.
My question is how do I subtract the 12 hours.
Thanks

I created a module to generate the correct date to begin manufacturing. There are two sets of criteria. If the job's prefinish is a certain code then manufacturing takes 7 days. If the job's door style is a certain code then manufacturing takes 5 to 6 days. Otherwise the date range is 4. Prefinish takes precedence over door style. I have units that have the special prefinish and one of the door styles listed then it gets the door style days instead of 7 days. Any ideas?
Function CreateWOSDDate(ByVal PreFin As String, ByVal DrStyle As String, ByVal DelDate As Date) As Date
Dim intNumDays As Integer
Select Case PreFin
Case "BR17", "BR28", "WH06", "BR06", "BR11", "WH17", "BR00", "BR22"
intNumDays = 7
Case Else
intNumDays = 4
End Select
Select Case DrStyle
Case "DCREag", "DCRHWK", "DCRFAL", "RP-9", "RP-22", "RP-23", "Eagle", "H/E", "F/E", "FALCON", "AR756", "HAWK", "RP22", "RP23", "RP9", "EAG", "HWK", "FALCN", "SHAKER", "NEVADA"
intNumDays = 6
Case "PAC"
intNumDays = 5
Case Else
intNumDays = 4
End Select
CreateWOSDDate = MinusWorkdays(DelDate, intNumDays)
End Function

Is there a way to show the earliest and latest dates of a report generated by a non-date field?
E.g. I generate a report based on Food, and it'll list the days that this food is associated with. Is there a way to show the first and last day that appears in this report (i.e. the range of dates that the report shows based on the food selected)

I have a database which stores information relating to club members, which I'm in the middle of giving a bit of a facelift and one thing I want to automate is the calculation of the expiry date.
My memberships expire annually at the end of December and the expiry date is set as a default value within the table properties. This has to be manually changed every September (every new member from then pays for 15 months) to the following December.
Is there a formula I can insert in the defaul value field that will return December the current year if todays date is between January and August, and December next year if todays date is between September and December?

I have a Continuous form where I am trying to add a calculated feild that allows us to see how many days a client was in hospital. There is a start and end date. I want to see the following: If start date and end date are the same, this should show client in hospital for 1 day, not the default of 0. If start date 5/1/13 and end date is 5/3/13 it should show 3 days in hospital. If start date is 5/1/13 and there is no end date, this should show 7 dates (from start date to today's date or current date). Currently I have
=DateDiff("d",[EStartDate],[EEndDate])-([EStartDate]=[EEndDate])
but it only shows 1 if the start date and end date is the same. I need it to include the start and end dates typed in its equation.
