One of the commonly used transformations in ETL is Table denormalization.
Denormalization is the reverse of normalization. Row-based data with key-value pairs is transposed into column-based data. This allows an OLAP model with one measure in each row (with the measure name as a key) to be arranged into a relational model in which the measures are held in various columns.
Jedox knowledge base
In typical table denormalization, Measure fields are populated by the rows which we want to see in columns. Usually, it's enough to do it one by one but sometimes it happens that there are 30 or 50 elements that needed to be transposed into the columns.
For that reason, we will use a little trick that can be found in Advanced settings. In case you are not familiar with this type of transformation here is the link that can help.
Our file contains 3 columns and one of them contains data that should be denormalized.
Instead of using static measures, we will introduce...
When working with dimensions like products there must be a use-case when mapping matrix is necessary. This little mapping matrix is used when there are certain years where some products are plannable and some others not. For this example, we will use the Mapping_Matrix database and cube Mapping Products.
This cube will contain dimensions like Years, Products, and Measures [not necesarry]. In some terminologies "Control cube " is also used.
As we could see from the image above in hidden columns we will store PALO.DATA formula. Behind the Check and Uncheck icons we could see the following code:
=HYPERLINK("SELF",IF(I8>0,iCheck,iUncheck),"",IF(I8=0,"!1","!0"),I8)
This hyperlink function just make difference if the value is 0 or higher. In case it's zero then every click on the iUncheck image will splash ! 1 on PALO.DATA function. Otherwise !0 would be splashed.
More on splashing commands can be found here.
The whole project can be downloaded from here....
During the planning process, there will be activities that require to copy data from the previous year or another version. There are multiple ways to achieve it via ETL but in this article, we are going to show you how to do it via hyperlink.
Copying using native copy/like function
If you ever attended any Jedox training you have probably learned splashing commands like Copy and Like. Both of them can be found on the knowledge base and this is good pre-knowledge for the following segment.
Copying using hyperlink function
Copy and Like function could be converted into the hyperlink and do the same job.
In the cell where you would like to create a hyperlink copy the following code.
=HYPERLINK("SELF","Copy Data","Copy Data","Copy "&F$5,$G6)
This code is another way to represent "Copy 2017" and G6 is a cell to where we want data to be applied.
Copying using hyperllink in the button
A similar thing is done in the next example but only instead of the hyperlink, we are...
Setting the default page in Jedox for a specific group is not a big issue if your application contains a smaller number of groups. When a number of groups enlarge, we should look for a more alternative solution instead of checking the boxes one by one. This represents 1st way.
Information of the default homepage is stored in the dimension GROUP_PROPERTIES, more specifically in the prefs element.
More about the system database could be found here.
Once we check this box from picture one, XML code is immediately generated and information on the default page is written. This code could be now pasted in every other cell. In that way, we could significantly decrease the time of checking and as well automate a bit process. This represents 2nd way.
3rd way would be to use this code and copy it via ETL.
Import to have in mind is that once a new start page is chosen code needs to be arranged. Also, if the Start...
Than the issue is mostlikely related to the return err, where the refresh statement is before the close and message statement:
WRONG:
{return array( array('actn', 'refreshData'),
array('actn','closeWindow'),
array('msg', 'STRATOS', 'Info', "Success Message is generated"),
);}
This can be fixed by putting the refresh after the message:
CORRECT:
{return array( array('actn','closeWindow'),
array('msg', 'STRATOS', 'Info', " array('msg', 'STRATOS', 'Info', "Success Message is generated"), "),
array('actn', 'refreshData')
);}...
Jedox has a wide range of possibilities when it comes to reporting since it is working based on Excel technology. Having that in mind it might happen that sometimes you will need to add a colour picker to your dashboard.
Here is an example of how it could be done.
On the spreadsheet, you can put the colours which could be chosen
Set up a macro which will be trigged when colour is clicked
="<a href=""#"" title='"&U5&"' style=""height:100%;width:100%;display:inline-block;color:"&U5&";background-color:"&U5&";"" onclick=""Jedox.wss.macro.exec([true,['Module1.saveColorToVariable','"&V5&"']])""> </a>"
Create the macro in the Macro Editor
function saveColorToVariable ( $color )
{
define_variable ( 'varColor' , $color );
//return do_close();
}
That is it!! In case you are not a person who has much sense for colours, there are amazing patterns of colours on this website.
An example of the project can be found here....
Here is the sample of the macro PHP code which can help you to return the IP address of the current server from the spreadsheet.
It could be useful when reports contain download functionality which is the source on the server name. So in order not to have a hardcoded server DNS name you could use this funcionality.
--------
function temp(){
$localIP = getHostByName(getHostName());
return __msgbox("myComplexVariable=".print_r($localIP , TRUE ), 'Test', 'Info');
}
--------...
When crafting reports in Jedox, it's not uncommon to encounter scenarios where the large volume of rows becomes unwieldy. In such cases, the implementation of paging proves invaluable. Paging not only ensures a clear presentation of the table but also serves to optimize server resources during report access.
In the example provided below, we illustrate a two-step approach to introduce a paging solution, leveraging the Jedox BikerBest database.
Step 1: Create the Table of Elements
The table, presented via Dyna-range, reveals an extensive list of elements that stretches to the bottom, posing navigation challenges. To address this, a subset of Dyna-range is strategically employed to showcase all base elements within the 'Product' dimension.
Step 2: Limit the number of rows based on the variables and introduce paging
It's common practice to incorporate external variables into the subset.
StartPosition - > from which element we want to start [Inital 0].
NumberOfElements -> how many elements we want to see in the table [editable but set on 30 for...
Jedox provides many possibilities when creating a report or a dashboard. Apart from native components like buttons, combo, and checkboxes, lists and dynaranges Jedox allow developers to code their own widgets. One of them could be the slideshow widget. This widget can make your dashboard more interactive and interesting.
Widgets in Jedox are coded via HTML and this is how you can create one.
For our example, we will use Biker's best database whereas for dimension Product we will add attribute images. Value of attribute is the location of the image behind [ Example /pr/jedox/images/Bikes/Mountain Bikes.png ]
Idea is to create an array of elements that could be used in the widget, which will contain:
Product Name
Product Image
Data of selected Measure
Measure
That we will do with Dynarange and it should look something like this:
Since coding behind the widget is a bit complex there will be a project available for download here.
To learn more about widgets and what possibilities you can have with them check the...
In this post, we will show you examples of an exchange rate cube, a planning cube, and how to set up the rules between them. This topic is very much present in a lot of projects and therefore we will explain the simple logic behind it.
Exchange rate cube
For every project exchange rate functionality is probably one of the must-have cubes. The logic behind is simple. We need a place to store rates and the place where we calculate them with the planned data. For keeping rates somewhere we need a cube with at least 2 dimensions:
Month or Day
Currency
It is important to dedicate one reporting currency. In our case the central currency is EUR. All the other currency data will be converted to EUR.
Another cube is the place where we plan the data. This cube will contain more dimensions like:
Month
Version
Country
Currency
Measure
In the end connection between these two cubes will be done by a rule:
In this rule, we are dividing data that is...
