I am creating a data blend and combining 2 excel files. I have volume
data dummy as primary data source & lifecycle dummy as secondary.
The common key is Ticket Id. Have created a calculated field to find the ticket
time which is Ticket Time =
DATEDIFF('day',ATTR([LifeCycle Dummy].[Assigned]),ATTR([LifeCycle Dummy].[Closed]))
Now i am not able to figure out how to show average ticket time per month or
at various other dimensions available such as priority, status etc. If i
remove the ticket id and only keep ticket time then the blend does not work. Do
advice if this can be achieved. Attached picture for reference.
If you want to show average ticket time per month, or any data based calculation, you'll need to join the data sources on Date also - looking at your screenshot they don;t appear to be linked yet. To enable them to be linked both fields must have exactly the same name, then you can click the paperclip icon next to the field to link it.

I have a question regarding a data entry form for project pricing estimates I am currently building.
To give you some context: The form will be used to enter data and complete calculations. It will replace an excel spreadsheet comprising of 59 columns, 1-15 rows (it varies by requirements) per project estimate. Average number of projects is 50-60 per year saved in respective customer folders. If there is an update to the estimate, a new version of the spreadsheet is created and saved in the respective customer folder. Hence, in certain scenarios, there are can be up to 10 versions saved per customer per project.
I am seeking to create a form-table combination for each of the customers: hence 10-15 forms with the same structure. Currently, I am only creating one form and table combination as a test. The table designed to replace the spreadsheet will use a total of 30 auto number foreign keys to store information. To be user friendly, I am using combo boxes in my form, where the user types in text but is stored as a foreign key in the table.
On top of this, I need to include calculations. For example, if the user selects certain options from my combo boxes, this will result in a calculated answer in an adjoining form field. Part of the calculated answer will use data in a linked table from another access database. Based on the options selected in the form combo boxes, the database will scan specific columns in the linked table to find matching entries to the selected combo box options. If a match exists, a price is extracted from that linked table. So say the combo box options selected are origin Miami and destination Salt Lake City, the database will scan for those 2 entries in the linked table. If that entry combination is found in the linked table, this price is to be used in the calculation. This price will then be multiplied by two other components entered by the user in the form, resulting in the calculated answer.
My questions:
Regarding the calculation example I gave above, can the above scenario be realistically accomplished in Microsoft Access? If so I am assuming I have to use VBA and/or Macros to do so?
a. If so, is it suitable to use my data entry form to complete it? Or is there an alternate way to achieve this result?
Will 30 combo boxes combined with such calculations have a significant impact on the speed of my form and database, especially as more data is added to the form and given that 10-15 forms will use the same structure? I have thus far included half of the combo boxes in 1 form, completed 1 test entry and I find that occasionally there is a slight lag when opening the form.
a. If it will impact my form's performance, what are my options/other form controls I can use to minimize lag and maximize speed?
Many thanks in advance!
The Cumulative Flow Diagram is useful, but its granularity is set quite large, i.e. you can only see numbers for the dates it chooses, which can be a week or more apart. However, it shows that under the hood, VSTS is recording the state of the backlog at every date.
It seems that the data must exist to find out the data I need (in this case the sum of effort for each state for PBIs) as it was at a given date - not just the dates picked by the chart for its points.
I've searched around but can't find it anywhere. Does anyone know how to do it?
To set date for Cumulative Flow Diagrams (CFD), you just need to click on the CFD and edit the date.
Such as to set the date of the CFD in backlog:
Click the diagram -> Edit -> specify the start date in Cumulative flow Tab -> Save.
Then the CFD will be changed based on the specified period.
To filter CFD by tag, type, Assign To etc, VSTS has not support this feature for now. But you can create an user voice for it, or you can calculate with your own code.
I've a problem with the dashboard in Tableau. In the dashboard there are many worksheets, and all the columns that are in the report are calculable. The problem is that dashboard is being formed for a very long time. The report contains approximately 2 million rows. And it is generated about 5 minutes.
Tell me, what are the solutions in this case?
Maybe I can somehow adjust the page display and not all the records at once?
To reduce the calculation time, try to exclude data you don't need with a data source filter in tableau. You can also hide or delete unused calculated fields. Other things you can do is reduce sheets that are not used.
Here's a link: https://www.tableau.com/about/blog/2016/1/5-tips-make-your-dashboards-more-performant-48574
Steps to follow to reduce calculation time:
Extract the data and use Extract data and also keep option as extract instead of live.Also replace the data source using extract data.
Use "User Filter" to reduce calculation time so that tableau will display of particular user data only.
I hope this will work to solve your problems.
I have one more idea to resolve this issue.
1)when you loan first time your dashboard put into Dashboard Action Filter
First Time load dashboard data exclude in your sheet.
Dashboard Menu->Action->add action->select sheet and exclude option.
2) Live to Extract data source and select radio button extract.
3)use user filter.
I am following the other answers (use extract, dashboard action filter...) and I want to add one point:
Drag every field used by any tablesheet on the dashboard on "Detail" of every tablesheet you are using on the Dashboard. Now Tableau loads all needed data while loading the first tablesheet and can use this data for the other sheets.
i.e. A dashboard contains three tablesheets (A, B, C) now you drag every field used by A on "Deatil" of B and C, every field used by B on "Deatil" of A and C, every field used by C on "Deatil" of B and A.
We are also having a similar issue with 150 million rows but I want to check if you are doing following steps. This may help you. This goes back to fundamentals of Tableau reporting.
1/ Try to make sure your data set is in star schema format. This will help a lot in report.
2/ Try to have tables and views in DB in such a way that same columns are used in Tableau. Any extra columns in tables adds to the performance issue.
3/Make sure indexing is done properly for all the fields that are joined.
4/ In my experience Dashboard adds extra performance lag. So make sure you try to get as much performance tuning on sheets as possible before even going to dashboard.
5/ If required try to use materialized views.
hope this helps.
Try to capture performance metrics using performance recorder option in Tableau.
Check for the underlying DB tables and joins present on the data source layer.
Try using optimized sets and parameters as required and get rid of less relevant filters.
Try using data extracts with scheduled refresh with data source filter for limited business years data.
I'm been using FM for the first time and have a need to use Get Summary on a financial information table. This generates various summaries of different income by customer, year and type. The layout generated from this table is good. The use of Get Summary allows me to do math with the various results, whereas sub summary totals by income type (as far as I know) cannot be added and divided by each other.
The problem I'm facing is that I wish now to create a layout based on customers and include some of the Get Summary detail from the financial table. Because my new layout is based on customers, I understand I cannot use Get Summary from financial as either a related field or in a portal.
The end game is simply to scroll through customer records, one after the other, and have key financial information show on their 'home' screen if you will, for years and type.
Any help gratefully appreciated. Thanks
I understand I cannot use Get Summary from financial as either a
related field or in a portal.
No, that's not quite correct. The GetSummary() function returns the sub-summary value by breakfield - if records are sorted by breakfield. Thus if the portal (or the underlying relationship) sorts the related records by type, you will see sub-summary values in the portal. However, you won't be able to see only sub-summary values, since a portal has no sub-summary parts.
There are other ways to show summarized related data. If you don't have (and don't expect to have) a large amount of records, considering filtering a (one-row) portal to show only a specific type of related records, then place the summary field inside it. Of course, this assumes the types are known in advance and unchanging.
I need to write an SSRS report that displays data based on user selected options (parameters). The report will be run on either paid or unpaid data. If the selection is for unpaid data, the report does not need a date value (it will select all the unpaid records in the database). However, if the user selects paid data, they should also put in a date range. Is there a way to either hide or disable the date parameters if the user selects unpaid data?
I have found several forums that indicate this isn't possible, but want to verify with the folks here on stackoverflow (I have a higher level of confidence with the responses here). I also looked at cascading parameters but this doesn't seem to fit that mold.
Thanks for your help!
