Sumproduct :: Forecasting Purposes
Oct 19, 2009
I am trying to come up with the appropriate formula that can be used for possible forecasting purposes. Countif proves to be futile due to more than one criteria that needs to be met. Sumproduct seems to be more feasible but I am unable to get the correct formula or maybe I am wrong.
Here's the objective...I need to be able to plot the total number of people working on a project on a daily basis - # of people working on a Monday, Tuesday and so forth by means of referring to start and end date column..I am open to revisions so as to streamline everything.

having an excel file autoname cells in order that I can hyperlink a picture to each tab individually.
Example - The file has autonamed tabs Wednesday 1, Tuesday 2....etc. In each tab is a reservation guide for three restaurants and the logo's at the top of the tab should hyperlink to a cell within the same tab. Blu Restaurant = A32, Grille = A223 within the same tab. How can I do this without manually naming the 3 cell's in each tab? I will also need this to be flexible so that when I create the January worksheet it populates from the tab names that are created using VBA already.

I am trying to sort by years (I have 66230 records to sort on) Parish Records that date from 1538/1659. The year as we know it now - did not come into existence until 1752 - and i have been trying to sort my data on the "years". I know i have done this before - however, i have either forgotten how to do it - or the Excel 2010 was not the version i accomplished this on.
Basically i have this:-
25 Sep 1596/97
25 Jun 1596
05 May 1611
10 Feb 1611/12
When i do a normal "sort" the split year comes before the main year as in 1596/97 comes before 1596 - thus putting all the dates out of sequence.
how to over come - i am no good with macro's - so if it can be done with using sort - it would be easier for me.

I am looking to sum the weight I add in my packing list spreadsheet.
below are two ways i have been working with and will settle with what ever i can get. all i need is to be able to enter the weight of a package either by lbs.oz or in separate columns (lbs)(oz) then have a formula take either way and know there is only 16 oz in a lb and give me a total weight of all things shipped.
.lbs
.oz

Excel spreadsheet, that contains several columns. Three of these columns contain text data that is selected by using a simple drop-down menu sourced from a list. If an attempt is made to enter text data not in the associated list an error message is displayed. Easy so far.
I need need to extend the text data validation across all three columns so that only specific combinations of the text in the three columns can be used which is reflected in a further list. These combinations will be counted elsewhere and so needed. Therefore, if i attempt to enter a combination of text columns that is not reflected in the list, this too will present an error message stating 'combination not valid', or words to this effect.

I am trying to put together a projection spread sheet for a client for cash flow purposes. I have it laid out but I cannot wrap my head around the formula and I've tried a few. Here it is.
A1: Client Name B1: Invoice Date C1: Projected Due Date ( I have 45 days added to B1) D1: Invoice Amount E1: Jan F1: Feb G1: March H1: April I1: May J1: Juneetc...
I am trying to forcast out the invoice collection date (C1). So basically in the month of June column I am trying to say if C1 falls between June 1 & June 30th then it should equal D1 (the amount due in that month). So if the invoice has a due date (C1) that falls in that particular month than I am forecasting the cash flow in the month it's collected.

If I have a database of 1000 records that are logged and counted as to which of these records are successful and unsuccessful sales,
can excel be programmed to give an accurate forecast of what will be the number/ percentage of successful sales records over the next 100, 50, 30 and 10 new record entry ranges, using the database history?, then which of the new records within each selected range are most likely to be successful sales using the database history?
If so, what components or data references are needed in a worksheet to meet these requirements to allow for creating an accurate forecasting application within excel?

how to play with data ranges and define names for charts to automatically update them by using the formula offset + counta. An example would be: =OFFSET(Sheet1!$B$7,0,0,COUNTA(Sheet1!$B$6:$B$37)-1).
So, the problem comes when there is a need to select a data range which is not that well defined like $B$6:$B$37. So, I need to import data regularly into my workbook, this data will be imported right below of the last cell with values.
Now, how would I manage to automatically select the data range from this new import for my chart? See attached example. I have highlighted in Yellow a potential import... there is no data in there so feel freel to fill it with any numbers you like.
I have tried to use a vlookup to find Country+Programme+Year (cat1 in the example) in the 'counta' part of the formula above. But I get lost,as a vlookup would retrieve a value and would not be useful for the data range?

I thought about using it for forecasting purposes. I might try to use it together with live data (temperature, seasonal patterns)... but if I graph it, it starts from left to right...
How to modify the code a bit...
VB:
Shift:=xlUp, CopyOrigin:=xlFormatFromRightOrDown
I tried to change the code, but it did not worked.

Forecasting using historical seasonally effected data
I organize my thoughts in numbers so it will be easier to understand.
[1] Say I have this data from January 2009 to December 2009:
1-4-7-10-13-14-15-16-18-20-22-25
As you can see, the growth is not linear.
[2] So then, I start with this data point for Janaury 2010.
26-a-b-c-d-f-g-h-i-j-k-l
[3] I now want to forecast that data point for the rest of 2009...using the growth in [1]. SO i guess that's an easy task right? Take the percentage change from Jan 08 and Feb 08...and apply that to the 26...and so on. (am i correct here at least).
[4] But lets say we have a GOAL. So, this become a forecast/plan. In December 2010, i want to grow double the amount of that in December 09. So 25 x 2 = 50. Now, the "known" data is like this:
26-a-b-c-d-f-g-h-i-j-k-50
So how do i do this now?

I have historical sales for each month from the last 3 years. I would like to set up a seasonality adjustment for forecasting. I know that it won't be perfect and some may even suggest using regression, but I'd rather not. I'd like to do the following:
In a control sheet, list the months in chronological order beginning in cell A1; January, A2, February; etc., etc. through December.
Next, below each month, I'd like to have a factor. For example, in B1 beneath January, I'd like to be able to plug in 75%. This would say that for each January going forward, that it is 75% of the annual historical average for all periods. Whereas, say in June, it is 140%.

how I would go about setting up a spreadsheet that will allow me to look at previous orders and forecast what I need to buy. He never got into trouble for ordering too much, but he did get caught on ordering too little. I am thinking something along the lines of the attached. However, if anyone is using something that looks or works better (or those who solve this little problem have done a better looking or working sheet) let me know.
There will be some Vlookups that need to bring in description and price (or some other function if there is a better way to do it). The min need and max need will be populated and brought in by vlookup. The order column should be where the forecasting happens based on previous orders. I am willing to have all the data in the same workbook. The second or third sheet can be used to store data in what ever format that is needed to be done.

I have the following formula's:
SUMPRODUCT(($O$9:$O$259="Active")+0)+SUMPRODUCT(($O$9:$O$259="Clearing Tmrw")+0) and
SUMPRODUCT(--($O$9:$O$259="Active"),$B$9:$B$259)+SUMPRODUCT(--($O$9:$O$259="Clearing Tmrw"),$B$9:$B$259) and
SUMPRODUCT(--(YEAR($A$9:$A$259)=$E$4)*($O$9:$O$259="Active"),$B$9:$B$259)+SUMPRODUCT(--(YEAR($A$9:$A$259)=$E$4)*($O$9:$O$259="Clearing Tmrw"),$B$9:$B$259)
My spreadsheet A1 to Q7 are where the headers and above formula's are and row 8 is hidden and has other formula's in (col C,M,N,O,P & Q)
The User then clicks the insert row macro which inserts a blank row (with row 8 formaules) into row 9.
However, the above formula's then change from 9 to 10 therefore, not picking up all the amounts.
Can anyone help me so that the formulas continue from row 9 ?

I have a spreadsheet in which I am using SUMPRODUCT. As you can see from the attachment, on the "Breakout by PIpeline" tab, Columns C, D & F are working perfect. However, Column B & E are duplicates of C & D - just wanting to pull the volume from the "Detail" tab instead of the dollars...and I keep getting the #VALUE! error.
I have tried formatting the Volume column differently - and even multipling the data times -1 and then pasting back in.....

I have a report with a macro that imports a .TXT file into Excel then calculates the follwing formula. For some reason, before the .TXT file is loaded the formula is fine and has no errors, then when it is run I get a "#NAME?" error. I thought it might be because the formula changed during the macro but that's not it. Examples are below.
I've looked online and tried naming the ranges, but that doesn't work. I've tried the built in help but that didn't help. I've tried making sure the analysis pak is installed but that's not it either.
I've ran out of ideas now and you guys are my last hope. Any clues...??
Before macro:
=SUM(SUMPRODUCT(--(DelDate>=6),--(Branch=$B3),--(Status"DEAL"))-SUMPRODUCT(--(DelDate>=6),--(Branch=$B3),--(Status="AWAI")))
After macro:
=SUM(SUMPRODUCT(--(DelDate>=6),--(Branch=$B3),--(Status"DEAL"))-SUMPRODUCT(--(DelDate>=6),--(Branch=$B3),--(Status="AWAI")))

I've got a spreadsheet that had _many_ sumproducts and calls to vba functions and when it recalculated took some time to finish, so I thought I'd group the vba function with the sumproduct to see if it was faster, but I keep getting a #Value! error. The sumproduct layout worked fine on the actual spreadsheet, so I'm sure something is lost in translation. Here is my
