There are a few answers here already that have part answered my challenge in Access but not fully.
I have 2 tables that form the basis of my database: customers and items
I have a further 2 tables; one for order quantities against customers and items (orders_a), and one for forecast quantities against customers and items (forecast_a).
forecast_a and orders_a also have a date for each customer and item combination (basically there will be 12 dates only for the 12 months of the year - 01/01/12,01/02/12,01/03/12 etc.)
Because a user will want to manually forecast quantities for a full year for each customer and each item, if there were 2 customers and 2 items, the forecast_a table would contain 48 rows. 2 items x 2 customers = 4, 4 x 12 dates = 48. The same goes for the orders_a.
I know this is a slightly unusual set up but the user requires visibility of a full year.
My main challenge based on this is as follows:
A user will want to see a form with customers in the first column, items in the second and then (like a crosstab): Jan Forecast Qty, Jan Order Qty, Feb Forecast Qty, Feb Order Qty etc.
Therefore how would I create a crosstab to pull both these tables together, and how would I go about creating a form for data entry off the back of it?
I may well be constructing my database the wrong way but the fact that the user needs a 'grid' where every entry is manual means I can't just have a form that creates a record one at a time for orders or forecasts.
Thanks in advance!

The problem you have is that this is a task that is in essence a spreadsheet task. Accordingly it may be best handled in Excel. To achieve this create an Excel object, create a blank worksheet, populate it with the data, then have a button to suck it back into the database when the user has finished.

I have 10 different products (A,B,C),..,J)have multiple purchase dates (by various customers) and delivery dates. I want to see which products have the date difference of less than 5 days. If the date difference is less than 5 days, which products have customer rating less more than 3.If the above criteria is satisfied I want to fetch those products that has the minimum date difference from the queue along with the "Important_date".If there are same minimum date difference for a particular product then I would like to select the top one among the same product in recent times and mark the purchase date as the "Important_date".
The columns in the table are: Product,Purchasedate,deliverydate,date_difference,customer_rating.
I am trying to use case statements to solve the problem in PostgreSQL.
I am looking for an output which will give me all the columns of the table along with "Important_date."
I have two tables. The first, table A, has dates, unique codes and costs. The second, table B, has dates, unique codes and revenues. Table A = >> Table B (One to Many Relationship). Now what I'm having difficulty with is running a find that gives me all the Costs in Table A and all the revenues in Table B for a specific period. The goal is to be able to calculate the cash basis for the period which is just cost + revenue for the period.
This seems like it should be a simple problem, but every time I run a find on Table B list layout, it does give me all revenue from Jan 1 to Jan 15 but if the related cost occurs before Jan 1 then it includes those two and they shouldn't be accounted for in the formula. Also if there are costs that occur between Jan 1 and Jan 15, even if there is no revenue in Table B that occurs between that period they should be included.
So I'm pretty lost at how to do this without running two finds on two tables to get the correct number then manually adding them together.
I cannot say I fully understood your description of the two tables. It sounds like you want to do a search in the child (Revenues?) table for records where both the date and the parent (Costs?) date are within the required range?
I'm very new to Tableau, and (maybe because of that) struggling with a graph setting. I need to plot a simple line graph showing the ratio between the number of users that returned after registered x days ago and the total number of users that registered x days ago (regardless on the fact that they returned or not). To do this, I have two tables: TableA having (simplifying) USER_ID and DATE_REGISTRATION, and TableB USER_ID and VISIT_DATE. Both table are joined by USER_ID.
I'm able, of course, to plot each individually (i.e. count distinct of USER_ID with DATE_REGISTRATION on the x axis to get the number of new users registered per day), but not able to combine them. I guess the problem is that I'm using either DATE_REGISTRATION or VISIT_DATE on the x-axis, but in this case I can get one or the other info, but not the two combined.
Ultimately, I would like to be able to have, for each date, both the number of users visiting and the number of user who registered.
Thanks a lot in advance.

Well, problem is your database is not ready to generate those analysis. Your table is user_id oriented, meaning you can do lots of analysis centered on the user_id. To do date oriented you need a table like:
Date User_id Type of event
01/01/2014 1234 Registration
02/01/2014 1234 Visit
Then you can drag Date and Type of event to Columns, and COUNTD(User_id) to rows, to get a bar chart that will show, for each day, how many people registered that day and how many people visited that same day.
Additionally, you can still join this table with the one you have, to have the registration date for each user_id. That way you can, for instance, calculate how many days have passed since registration.
I am a beginner in iReport and I cant program Java so I hope you can give me an idea.
I've already managed to make a chart that displays how often all customers have ordered in february, march,... etc.
Thats how I did it:
In category expression I have: $F{Month}
In value expression I have : $F{count(Orders)}
But I want to display how often only one customer (for example customer a) has ordered in february, march,... etc.
I have the following values which i can use:
Month, Orders and Customers(here are all customer names saved)
-------//-----------UPDATE--------------//-----------------------------------
I want to display a chart which represents the total orders per month of a customer. But iam trying to display my 3 customers (my database has only 3) in only one chart (stacked).
For example(see picture above): I want to display the total orders from Customer A (yellow) in february. And I want to display the total orders from Customer B (blue) in february and the same for customer C.
The customers should be displayed stacked (3 in every month) and every customer should have a different color plus the total orders from every customer should be displayed ...like in picture above for example:
customer A(yellow) made 3 total orders in february, Customer B(blue) made 2 total orders in february, customer C..etc.
it is very important that every month displays 3 customers...stacked.
How do I do this?
I appreciate every idea.
From what I have understood from your question, you want to show a chart which represents the total orders per month of a customer.
You need not use stacked bar graph for this purpose.
You may want to use bar graph which would serve your purpose.
If you want to see the chart per customer, create one parameter $P{customer} and pass it into your query.
Refer document iReport-Ultimate-Guide-3 on how to create parameters and to use it in queries.
e.g:
select customer,month,count(orders)
from <your table>
where customer=$P{customer}
group by month
The above approach would work if you want to see the details for only one customer.
**Here is my solution after your update.**
From your update, it seems like you want to represent the total orders per month for all the customers.And you want to use stacked chart for the same.
Then what you have done is correct but have missed to add a field to your 'Series Expression'
Add your field customer to your series expression and this will resolve your problem i.e,
Series Expression : $F{customer}
Category expression : $F{Month}
Value expression : $F{count(Orders)}
This will display the chart in the format you have specified.
Create a paramter that takes your customer name $P{customerName}
and another takes month $P{month}
pass these two paramters to your sql like that
SELECT customer_name, order_count FROM customers
bla.. bla..
WHERE customer_name=$P{customerName} and month=$P{month}
then create a chart with only one serie to show one customer as one color. Not like yours with 3 colors.
Fell free to ask for more specific detail.
If I have a report that tracks data for several accounts for each month with rows labeled:
UNITS,
REVENUE,
AVG REV/UNIT
How would I create a query that will filter the report to just show accounts where the UNITS row has increase/decreased 25% and the AVG REV/UNIT has increased/decreased 10%, from the previous month to the current month.
An example would be for the month of June I have the numbers....
JUN
UNITS 3,271
Revenue $3,598.10
Avg R/U $1.08
So when I run the report at the end of July I only want accounts that have a 25% difference in UNITS and/or a 10% difference in AVG REV/UNIT to show on a report.

You should do it with more than one query. In the first query, select the data for the first month. On a second, to the desired month to compare. Create a third query that links the two first (be care about the correct relationship). Do the grouping/calculations in these queries.
In the 3rd query, create two fields that calculates increasing/decreasing for units and rev/unit. Now, you can add a criterium on each parameter field in the query columns.
The chalenge here is to be sure about hou would you work with the primary keys on months. Eg: if a A row in the first query isn't in the second (for not having an event on second month, for example), it will not be showed. In this case, the solution would be to create the queryes linking a table or query wich has the entyre set of registers, forcing it to show all the desired records despite they have or not occurrences.
