BIRT. Average function without value '0' - eclipse

I am making reports with BIRT. I have table with "item planed quantity", "finished quantity", and percentage. Something like this Planed 50 , Finished 20, Percentage 40%... and etc.
and after this line i have sum of 'planed quantity', sum of 'Finished quantity'
and ave of percentage. the main problem is that this ave formula is taking percentage whic is equals to 0.
Anyone know how to set filter or expresion like "measure["percent"] != '0'" or something like this?

for the record, 192.168... is a purely internal IP. Unless someone is on your LAN, they won't have access to it. This means that nobody on the WAN can see the link you posted.
As to your issue - here are a few things to try:
1. Check your data type. I think integers round down so AVE( 12/13 ) will equal 0 instead of 0.923.
2. If your wanting to avoid zero values in your average, you'll need to gather counts of non-zeros which requires some scripting. You'll probably be best off creating a scripted data set for this.
See if you can take a screenshot and attach it to this issue if neither of these ideas work or if you need further assistance (particularly with the second option I suggested).
Thanks!

Getting a percentage in Tableau from a yes/no column

I have a spreadsheet of support case management data. I am working with this in Tableau. Each line in the spreadsheet is an individual case. Each case has, among much else, a support agent name and a Yes or No of whether the case work was started within 12 hours. I'd like to know, for each agent, what percentage of the time they started the case work within 12 hours. So, if Bob has 2 "No" and 8 "Yes", he should have 8 / (2 + 8) = 80%.
My attempt at this was to create 2 sets. One is the set of "Yes, started within 12 hours" (those that have "yes" in that field, and one that is the set of "No, not started within 12 hours", the complement to the other set. Silly me, I thought I could do something like COUNT(yeses) / COUNT(nos). Nope, big red failure. So what is the right way to do this?
It would help immensely to please respond as if this is the first thing I have ever done in Tableau. It is. I have learned a lot in this project, but only in comparison to the nothing I knew previously. Please also let me know if I've left out something necessary to answer this. I've tried to be complete but, well, am noob...
If it clarifies anything, here's a poor Excel mockup of data and the effect I'm looking for:
Yes, this is possible and easy in Tableau, but first a couple of points.
The reason your attempt to use COUNT() did not work is that COUNT() does not operate the way you, and that 99% of the people on the planet, expect. COUNT([some expression]) returns the number of records that have a non-null value, any value, for [some expression]. The name comes from SQL relational databases.
The calculations would be just a bit simpler if your third column took the boolean values True or False instead of the string values “Yes” or “No”. (In which case you could drop ‘= “Yes”’ from the formula below)
So two ways to do your calculation are:
Directly with an aggregate calculation which can get the right result, but is hard coded for this case, such as:
SUM(INT([Started within 24 hrs?] = “Yes”)) / SUM([Number of Records])
Using a table calc - which in this case is a bit easier and more flexible.
First, Build a table or viz in Tableau showing SUM([Number of Records]) with the dimensions you care about in play. Say with [Name] on Rows, [Started within 24 hrs?] on Columns and SUM([Number of Records] on Text. Second, Right click on your measure SUM([Number of Records]) and choose Percentage of Total from the Quick Table Calc menu. Finally, use that same menu to adjust Compute Using to specify how you want the percentages computed - in this case, using [Started within 24 hrs?]
If you only want to show some of the data, right click on the column header for the values you wish to hide and choose Hide.
The type conversion function INT() converts True to 1 and False to 0.
You could create another column that converts the Yes's into 1's, and the No's into 0's. Sum up all the 1's and divide it by the total and that's your percentage.
edit: the new column would look something like
=IF(C3="Yes",1,0)
in other words, if Cⁿ is "Yes", then 1, else 0

Cognos Report Studio - Grouping/Filtering

Truth be told I'm not entirely sure what it is I'm trying to do here, well, that is I know what I want to achieve, but not how to go about it... so here's hoping you can help point me in the right direction!
I need to create a Crosstab report which has customers down the side, dates for columns, sales for figures. Simple enough.
Where it gets tricky is that they then want another row beneath the customers which singles out two customers, and their sales for one particular product.
They then want another row which will remove that figure from the total of the overall sales total for the first section (see example image).
I'm not really sure where to even start with this. I think I may need to use a query union, but every time I start I get kinda stuck... help!
That's not a crosstab. The summary calculations don't work. It's probably going to end up being three crosstabs formatted to look like a single crosstab. The first crosstab is everything down to the Total line. The last two lines are each crosstabs. Set the Size & Overflow, Padding, Margin, and other formatting properties so everything is layed out, bolded, and shaded the way you want.
You can create this as a crosstab
If you are okay with setting each customer as a fact
You can add them to a crosstab in any order you want
Then you can create a new data item and use a conditional statement that sets the metric to be the specific customers the consumer wants
For example,
IF([Customer] IN(?PrmCust) Then([Sales])Else(0)
For the revised total, unlock the report and replace them with layout calculations that take the total and reduce it by the amount of the selected customers

How to get the sum directly with one number?

I'm a beginner for tableau. I want to get the direct numbers for each row, but i get the number which are separate, how can i achieve this?
I've tried the sentence like:count("Implemented"), but I don't get the result I want.
For example, for the 1st row I want 3 10 10
not 111 10 112111111
Here is worksheet.
My code:
EDIT :
here is the photo for implementation opportunities
As you can see, the status is related to the date, I think maybe it causes the records which are counted 1by1.
Now the situation is that: i create the code which is related to the date, if i remove this from mark, it will cause the problem (the code is related to the date), but if i leave it, the system will always count it one by one. My code is not perfect but i can't find another one which can replace it.....
EDIT 2:
in short,what i want is the sum of the remaining opportunity:10
capture
Remove DAY from Mark shelf. That detail is producing those separations.
Attaching a workbook with numbers similar to (but not exact due to proprietary issues) is almost always advised. You will get the right answer a lot sooner than just screenshots.
In any case, it seems as if the measure portion of the visualization is properly being summed by the date. Try selecting the measure, and manually selecting "sum" from the menu drop down. Here is a link for more detail.
Secondly, you can play around with table calculations. Click this link and read up on option 3.

How to get all missing days between two dates

I will try to explain the problem on an abstract level first:
I have X amount of data as input, which is always going to have a field DATE. Before, the dates that came as input (after some process) where put in a table as output. Now, I am asked to put both the input dates and any date between the minimun date received and one year from that moment. If there was originally no input for some day between this two dates, all fields must come with 0, or equivalent.
Example. I have two inputs. One with '18/03/2017' and other with '18/03/2018'. I now need to create output data for all the missing dates between '18/03/2017' and '18/04/2017'. So, output '19/03/2017' with every field to 0, and the same for the 20th and 21st and so on.
I know to do this programmatically, but on powercenter I do not. I've been told to do the following (which I have done, but I would like to know of a better method):
Get the minimun date, day0. Then, with an aggregator, create 365 fields, each has that "day0"+1, day0+2, and so on, to create an artificial year.
After that we do several transformations like sorting the dates, union between them, to get the data ready for a joiner. The idea of the joiner is to do an Full Outer Join between the original data, and the data that is going to have all fields to 0 and that we got from the previous aggregator.
Then a router picks with one of its groups the data that had actual dates (and fields without nulls) and other group where all fields are null, and then said fields are given a 0 to finally be written to a table.
I am wondering how can this be achieved by, for starters, removing the need to add 365 days to a date. If I were to do this same process for 10 years intead of one, the task gets ridicolous really quick.
I was wondering about an XOR type of operation, or some other function that would cut the number of steps that need to be done for what I (maybe wrongly) feel is a simple task. Currently I now need 5 steps just to know which dates are missing between two dates, a minimun and one year from that point.
I have tried to be as clear as posible but if I failed at any point please let me know!
Im not sure what the aggregator is supposed to do?
The same with the 'full outer' join? A normal join on a constant port is fine :) c
Can you calculate the needed number of 'dublicates' before the 'joiner'? In that case a lookup configured to return 'all rows' and a less-than-or-equal predicate can help make the mapping much more readable.
In any case You will need a helper table (or file) with a sequence of numbers between 1 and the number of potential dublicates (or more)
I use our time-dimension in the warehouse, which have one row per day from 1753-01-01 and 200000 next days, and a primary integer column with values from 1 and up ...
You've identified you know how to do this programmatically and to be fair this problem is more suited to that sort of solution... but that doesn't exclude powercenter by any means, just feed the 2 dates into a java transformation, apply some code to produce all dates between them and for a record to be output for each. Java transformation is ideal for record generation

Ok... so you could override your source qualifier to achieve this in the selection query itself (am giving Oracle based example as its what I'm used to and I'm assuming your data in is from a table). I looked up the connect syntax here
SQL to generate a list of numbers from 1 to 100
SELECT (MIN(tablea.DATEFIELD) + levquery.n - 1) AS Port1 FROM tablea, (SELECT LEVEL n FROM DUAL CONNECT BY LEVEL <= 365) as levquery
(Check if the query works for you - haven't access to pc to test it at the minute)

Crystal reports 2011 Math operations on running total fields

Been trying to do this for hours, so would very much appreciate an answer. Google apparently hasn't heard this question before; in fact, I could find very little information on this subject anywhere, including in the Crystal reports help functions.
I have three running total fields in a Crystal Reports 2011 report. I need to add two of them together and then divide that sum by a third running total field.
Here is what I have in the formula field I have created in order to do this:
(Sum(rtotal1))+(Sum(rtotal2))/(Sum(rtotal3))
The error I continue to get is: The ) is missing
Can anyone tell me the correct syntax for how to do this (aggravatingly simple) operation?
So I'm not sure what your running totals are (sum, count, etc.), but you shouldn't have to specify sum in your formula. I did a quick mock-up with 3 running total fields, each one a sum of a value. the resulting formula looks like this:
({#RTotal0} + {#RTotal1})/{#RTotal2}
I'm not sure if the brackets are needed, but since you want to add RTotal0 and RTotal1 first and then divide that result by RTotal2, I advise to put them in.
