[Parent-child hierarchy] Retrieve value for level without children aggregation.

May 25, 2015, 1:46 am

Hello,

I am trying to make an MDX query able to retrieve each node value for a parent-child hierarchy withou aggretatting values for children. But I am unable to do so.

This is an example parent-child hierarchy, like the one I have:
parent-child.png

As you can see, the lowest level (D) has a value of: 56.998.

I know that D's parent (C) has also the same value: 56.998
But when asking for C values, Mondrian is taking into account not only the C own value but also all it's children aggregation value. Do any know how to construct an MDX query that only retrieve facts for each level without aggregating its children level facts?

Regards,

Alvaro.

Hi!

Here's the situation :
  • one database A with several tables (TA1,TA2,TA3,....)
  • one database B with one table like this [TA_names, TA_count]


I want to populate B table like this :
  • TA1 - 20 (rows)
  • TA2 - 156
  • TA3 - 7
  • ....


B table already have TA_names, so how can I update TA_count with something like "select count(*) as from ?"

We have a time dimension with Year-Month-Day levels (uniqueMembers NOT checked on the Schema definition).

We can get a simple Saiku table with Sales for each Year-Month, but no way to get a Chart with the correct data, months of all years are added up so we always get 12 months instead of a whole serie.

Saiku: switching from Table to Chart shows the correct results ... switching to MDX mode shows the code as

Code:
SELECT NON EMPTY {Hierarchize({[Measures].[Sales]})} ON COLUMNS,
NON EMPTY {Hierarchize({{[TimeDimension.DayHie].[YearLev].Members}, {[TimeDimension.DayHie].[MonthLev].Members}})} ON ROWS
FROM [CubVendes]
Clicking run and we get an additional columns for each year (columns we don't need at all). Curious enough than the generated MDX doesn't show the same results.

Now copying this MDX to a CCC Bar chart on CDE ... and we get only 12 columns with months of all years added up + the yearly sums :mad:

We have tried all syntax we can imagine with no luck.

Any idea would be appreciated. We just need one column per each month of each year ... seems simple enough :)


NOTE: Results are exactly the same without the "Hierarchize" function call.

Creating common style template for PDF-exported reports

May 25, 2015, 12:15 pm

Hello,

Is it possible to create a template that will have style properties for report header elements, group elements, and detail row elements, etcetera? I'm referring to things like font face, font size, text colour, padding, background colour of rectangles, size of rectangles.

Ideally I'd be able to create such a template and them apply it to a report when I start to work on a new report. When I drag elements onto the new report, they would inherit the styles of the template.

These reports will be exported to PDF when run in production, i.e. they will not exist in a web container.

Thanks for any help,

Ryan

PDI-CE Architecture / Functionality

May 25, 2015, 2:35 pm

I'm getting a bit mixed up on the Data Integration component of the Pentaho Business Analytics Platform:

1. I'm reading the InfoCenter docs which indicate that the ETL component is Data Integration (PDI) and the BI component is Business Analytics (PBA) and both have a bunch of sub-components and optional plugins. It further states the the desktop / client applications for ETL comprise of Spoon, Kitchen, Pan and Carte, as well as a separate DI server for security, versioning, and scheduling, etc. Now then, I'm simply using the PDI-CE version and assumed this architecture would the same albeit with reduced functionality - at least that's what the youtube videos I've been watching seem to indicate - however, I am unable to locate any separate DI server that I can install alongside my local PDI-CE version. Please can somebody clarify if PDI-CE can work with a DI server? because it does seem to offer the possibility to connect to a repository, but I thought that was managed as a service and required the DI server to be installed? In fact, am I basically reading the EE documentation? as I've just found a separate set of wiki documentation that is specifically for PDI (kettle).

2. I'm following this tutorial: http://infocenter.pentaho.com/help/i...formation.html and the relevant sample data IS bundled with PDI-CE but I'm stuck at the database connection step. Apparently I should have a local database installed of the "H2" connection type that I can use for writing my output to. Obviously I don't have any such database installed but there's a yellow box in the tutorial suggesting that this is all related to the DI server again. So is database installed as part of the DI server? and how does it fit in with the PDI-CE version I'm using?

Disclaimer: I'm not dumb (i.e. I know what an ETL system is, coming from an Informatica and Oracle background) but I'm new to Pentaho and have clearly failed monumentally to grasp the architecture of this product.

Please respond fast! :D

Performance issues using SQL step fpr CREATE TABLE AS SELECT via DBLINK

Hi there,

we following issue: On starting a CREATE TABLE AS SELECT statement within the SQL-Step of a transformation the execution time is 2-5 times slower than executing the same statement in TOAD. The SELECT within the CREATE is using a DBLINK to pull the data fom another schema. Table size differs from a few MB up to 150GB.

It is an Oracle-Database 10g/11g. The user is the same for TOAD and Pentaho.

Does anyone have an idea why there is the difference and how to improve speed in pentaho?

Customizing Pentaho Report Designer

May 26, 2015, 5:24 am
$
0

Hello,

I want to use the (PDR) Pentaho Report Designer for a task a little different than what it was probably thought for: instead of reports, the documents I create with PRD represent ticket layouts for me, in the sense of tickets for event seats. I have used the PRD successfully and it will save a lot of time to my company. But for it to be the perfect tool, I need some changes, mainly constraints applied to the software as available in github.

I want any corporate user to be able to design a ticket layout for an event, but depending on the user role, they may be able to only see certain events, sessions, etc:


  • the user must authenticate in order to determine the access rights to data such as: facilities, events, sessions, etc.
  • instead of freely create new reports, the user will select Facility>Event>Session>Rate>Format and that will open an univocal document. This document is what I shall call Ticket Template. If it existed already, then open it in the state it last was; otherwise, open it in the initial state.
  • The initial state of the template ticket only shows the detail row (the structure tree tab can be hidden); the width and height as well as the guides are fixed according to the ticket format selected; the data source must be automatically set depending on the Rate.
  • When the ticket template is published (maybe using the Pentaho server), it should stay accessible by the PRD itself and other applications, e.g. later edition by the same or different user; thus it must remain properly identified.
  • Other unneeded functions shall remain hidden, e.g. datasource edition.


I have built and executed both the PRD and the Pentaho server successfully from the github sources; they look great!

I can start to dig into the codes and try to figure out how things work, but what I would really appreciate is some guidelines as to how best attain my goal and, even better, how could they serve the community.

Any comments will be appreciated. Cheers,

Claudio

CDE - Where to find error messages

Hello,

I'm new to CDE and I'm trying to build my first dashboard. Single frame with a simple bar chart. Data source is "SQL over sqlJndi"
When open the dashboard, I have an error message "Error processing component (chart_bar_01)" which is generic message. I suspect something wrong with my data source but I can't figure out what.
There must be some other more meaningful error messages stored in a log file but I don't know where (nothing in pentahlo.log nor in catalina.out).
Anyone to guide me through my first steps with CDE?

Thanks in advance.
