Is the SAP HANA Predictive Analysis Library used within UDF?
Hello Everyone,
I am an intern at SAP Belfast currently looking at UDF and DDF, and I was wondering if you could answer a few questions for me?
Is the HANA Predictive Analysis Library (PAL) used within UDF? I know that UDF uses regression analysis, and I know that the PAL has functionality for regression analysis, but are they used together? and if so, which algorithm within PAL exactly is used?
I know that the UDF is an Application Function Library. How many of these Application Function Libraries are there within HANA, as I have only come across the AFL which contains the Predictive Analysis Library?
Thanks a lot in advance,
Claire Burn
Hi Anu,
First double check your own heart. If you really have the passion, then go back to SAP and do what ever you want to do. You will definitely succeed. However if your motivation is primarily influenced by other than (your love for subject), then the question is how far and how long you will be able to stay before those thoughts come back and push you to switch to something else. The key is where your heart is. Only you can help yourself.Good luck.
Regards,
Sam

Use cases for the SAP HANA Appliance for SAP FI-Accts.Payable
Hello SAP HANA friends:
Are there any compelling use cases for the SAP HANA Appliance for SAP FI-AP Accounts Payable module?
CO-PA and CRM have many immediate use cases, but I'm looking for the use case for Accounts Payable,
either from a cash flow perspective or performance.
Any and all comments are appreciated.

SAP HANA rev 82 update using hdblcmgui or LCM in studio?
Hi All,
I am updating sap hana to revision 82 from revisoin 81. SAP has suggested to use hdblcmgui for update and LCM in studio is depricated from SPS8.
Using hdblcmgui I dont see an option to upgrade.
SAP displays a note on LCM, suggesting hdblcm, but the update is option is not disabled.
Can I continue to update using LCM or how to upgrade using hdblcmgui?
Please suggest

RajHi Stanimir,
Yes the IP associated in AWS console was still the same.Now I've terminated the instance since it was halting our development activity.We are using the trail version of HANA rev 72, at any point of time we can't bring in more than one instance through CAL so we have terminated the corrupted instance and recreated a new instance to proceed further.
But this is really strange behaviour and curious to know, if some else has faced this problem. Unfortunately i couldn't hold the corrupted instance to debug further.
Thanks.

Is the folder 'Master' in Referenced Library useful? Can I delete it?
Hi,
I've switched from a managed to a referenced library.
I stress that after double checking ALL my photos are now stored outside of the library.
When I show the content of the apertue library package I can see the Master folder still contain 25GB+ of photos.
What are thses files?
Can I delete them?
Thx!Over time you'll end up with more content in the Master folder. For example, if you edit an image in an external editor, Aperture automatically creates a new original (master). These automatically created originals are always managed. You will need to relocate them after the fact to make them referenced.

Set the column order in document library using power shell
hi all,
am looking for a power shell script which set the column order in the document library, when i try to upload a document.
ie; i am uploading a doc to the doc lib. which has the below columns:
columnA - [choice field - mandatory ]
columnB - [lookup field - mandatory ]
columnC - [single line of text - optional ]
columnD - [choice field - optional ]
columnE - [choice field - mandatory ]
now when the end user uploads a document in my doc lib, i would like to see the mandatory columns takes up the top order and then optional fields.
columnA
columnB
columnE
columnC
columnD
so, is there any script, through which i can set the mandatory columns which will be coming in top and the optional fields as next orderThis is sample PowerShell code to reorder fields in a content type of a list.
$web = Get-SPWeb http://aissp2013/sites/TestSite
$list = $web.Lists["MyList"]
$contentType = $list.ContentTypes | where {$_.Name –eq "MyTestCT"}
$ctArray = "Title","ColumnA","ColumnB","ColumnD","ColumnC"
$contentType.FieldLinks.Reorder($ctArray)
$contentType.Update()

Reset or clear words the iPhone 4 predictive text "library" has learned?
I'm going crazy because a few words that I have mistyped has become part of the prodictive text "library" on my iPhone 4. Every time I put "me" it always come up "me'" because of a typo. Is there any way you can clear these out of that "library"?
You can clear the entire dictionary (Settings/General/Reset) but not individual words. However, you can try tapping the "x" on the wrong word when it appears. After 3 times it should forget that one.

SAP HANA Performance Optimization
Hi Experts.
Is there any documentation out there that relates to optimizing SAP HANA components such as optimizing the SAP Hana models, data loading using SAP LT, etc. I would like to fine-tune what I have already built.
Thanks,
Regards,
Thatoyame
Email: [email protected]Hello Thatoyame,
since HANA is pretty fast in so many cases, there isn't much available about general performance tuning. In cases where performance isn't great, a detailed root cause analysis (i.e. trace) is the way to go. See SAP HANA Appliance Software – SAP Help Portal Page (Admin section) for some details on tracing.
For data modeling, check Werner Steyn's webinar at Building Advanced Data Models with SAP HANA - Webinar Details.

SAP HANA One and Predictive Analysis Desktop - Time Series Algorithms
I have been working on a Proof-of-Concept project linking the SAP Predictive Analysis Desktop application to the SAP HANA One environment.
I have modeled that data using SAP HANA Studio -- created Analytic views, Hierarchies, etc. -- following the HANA Academy videos. This has worked very well in order to perform the historical analysis and reporting through the Desktop Application.
However, I cannot get the Predictive Analysis algorithms -- specifically the Time Series algorithms -- to work appropriately using the Desktop tool. It always errors out and points to the IndexTrace for more information, but it is difficult to pinpoint the exact cause of the issue. The HANA Academy only has videos on Time Series Algorithms using SQL statements which will not work for my user community since they will have to constantly tweak the data and algorithm configuration.
In my experience so far with Predictive Analysis desktop and the Predictive Algorithms, there is a drastic difference between working with Local .CSV / Excel files and connecting to a HANA instance. The configuration options for using the Time Series Algorithms are different depending upon the data source, which seems to be causing the issue. For instance, when working with a local file, the Triple Exponential Smoothing configuration allows for the specification of which Date field to use for the calculation. Once the data source is switched to HANA, it no longer allows for the Date field to be specified. Using the exact same data set, the Algorithm using the local file works but the HANA one fails.
From my research thus far, everyone seems to be using PA for local files or running the Predictive Algorithms directly in HANA using SQL. I can not find much of anything useful related to combing PA Desktop to HANA.
Does anyone have any experience utilizing the Time Series Algorithms in PA Desktop with a HANA instance? Is there any documentation of how to structure the data in HANA so that it can be properly utilized in PA desktop?
HANA Info:
HANA One Version: Rev 52.1
HANA Version: 1.00.66.382664
Predictive Analysis Desktop Info:
Version: 1.0.11
Build: 708
Thanks in advance --
BrianHi,
If you use CSV or XLS data source you will be using Native Algorithm or R
Algorithm in SAP Predictive Analysis.
When you connect HANA, SAP Predictive Analysis uses PAL Algorithm which runs
on HANA server.
Coming to your question regarding difference,
In SAP PA Native Algorithm, we could provide the Data variable, Algorithm
picks the seasonal information from the Data column. Both R and SAP HANA PAL
does not support Date Column. We need configure seasonal information in
Algorithm properties.
R Properties
1) Period : you need to mention the periodicity of the Data
Monthly : (12)
Quarter : (4)
Custom : you can use it for week or Daily or hourly.
2) Start Year: need to mention Start year.
Start year is not used by algorithm for calculating Time series, but it helps
PA to generate Visualization ( Time series chart) by simulating year and
periodicity information.
3) Starting Period:
if your data is Quarterly and you have data recordings from Q2, mention 2 in
start period.
Example.
If the data periodicity is Monthy and my data starts from Feb 1979, we need to provide following information,
Period: 12
Start year: 1979
start Period: 2
PAL Properties. : Same as properties defined in R.
Thanks

Hello,
Scope: JVM error during initial install of SAP HANA Studio Developer Edition v1.00.80, Win86/32bit
Source: installation files pulled from HANA Studio tab at https://hanadeveditionsapicl.hana.ondemand.com/hanadevedition/, which is a link from the main HANA site of http://scn.sap.com/community/developer-center/hana. zip folder: "sap_hana_win32_studio_rev80"
Targeted O/S: Windows 7, 32-bit, local Java is SE 7, update 67. Java environment has been confirmed via checks provided at http://www.java.com/en/download/manual.jsp
Actions taken:
Attempted to update the installation's eclipse.ini file by reducing the -Xmx value; see details below.
Read thru postings such as http://scn.sap.com/thread/3390626 and the threads it recommended.
Checked OSS (ie Note 1859686 - HANA Studio does not start)
Description of installation error:
Shortly after executing "hdbinst", it fails with the error "Could not create the Java Virtual Machine". I've verified that there is nearly 3G of memory free. What I did notice, as shown in the attached files, is that Eclipse is part of this installation and it's pre-loaded with the "eclipse.ini". I firmly believe the solution could be to reduce parameter "-Xmx1024m" to "-Xmx512m" but it's a catch-22 because even after updating eclipse.ini (in installation folder C:\Program Files\SAP\hdbstudio\tmp_p2director2014.08.13_13.36.44\director), the install program requires that the "hdbstudio" folder to be empty upon restarting it.
Since the installation is basically a package with a lot of .jar files, there is no eclipse.ini file available in the source install folder; otherwise, updating it there would be the easiest solution if that option were available. The file is only available in the targeted deployment folder above.
If you have encountered this same error and were able to resolve it, I would be grateful to know of your solution. Thanks very much.
FYI: the HANA Client installed with no issues.

FYI: the images below reflect the sequence of images produced during the installation.
after clicking OK above, the screen below gets updated (see the "is not empty" msg).
Below is the eclipse.ini file located in the deployed/target folder:
Message was edited by: Jim Cleek
FYI: Using information from the SAP HANA Database - Studio Installation and Update Guide, I tried to override the installation's use of its eclipse.ini file by passing my own modified version (with "-Xmx512m") of that file that was placed in a separate folder. The cmd used via DOS window was "hdbsetup.exe -a studio --configfile=C:\Users\Admin\Downloads\eclipse.ini" and even though it successfully launched the SAP HANA Lifecycle Management gui, it failed on the first step with the same JVM create error as above because it appears to have used its own eclipse.ini file, which has "-Xmx1024m".Update: a message was opened with SAP but unfortunately they could not provide a resolution for this particular scenario. They admitted that the eclipse.ini file cannot be updated since it is bundled as part of the installation package. One point to make that I did not make before was that this was being attempted on an Oracle VirtualBox (4.3.10); the SAP HANA contact said he assumed that SAP has not tested this particular scenario, thus it could not be supported.
Resolution: the end result was to abort trying to install SAP HANA Client and Studio on the Oracle VirtualBox but to install it locally on my own desktop, which runs on Windows 7 Enterprise 64-bit with 8G of memory. The SAP HANA files below were downloaded, extracted and installed successfully in the order shown.
FYI: the Studio installation detected that a 64-bit version of Java was not installed so I installed that and then adjusted the User environmental variable JAVA_HOME to point to that new path, leaving the System variable still pointing to the pre-existing 32-bit Java path.

What could be the reason for getting this error message? I hope you can help me.
Thanks in advance.
CTHi Nicky,
As per my knowledge, there is no separate licensing required for HANA studio. License for HANA d/b or Enterprise HANA license is sufficient.
Installation of HANA studio will not ask for any licenses.

Our Reqirement:
Now we need to Build a Predictive analysis report around this data as follows:
1) The report should show the predictive analysis of liquid consumption by month wise, for each machine level.
Our query:
1) For this requirement what is the predictive analysis algorithm (function) we should use ?
2) What is the implementation procedure on the respective algorithm.
How can we build Types, input Tables ?
How can we build Parameters, how can we determine the Alpha value etc , for our requirement?
Our research and queries on the same.
WE went through a video (HANA Academy - Key Concepts of the Predictive Analysis Library - YouTube)on Single Smooth Algorithm, in that we query on Result.
The input was given as Calendar Id and Sales Amout, where Calendar Id starts from 0 – 23 , what is meant by this Calendar Id ?
And also the result is showing Calendar Id from 2-24 , why it is not considering Calendar 0 and 1
How can we say that the result is predictive and on what basis (like month ,year , date etc).
Thanks and Regards,
SomarajuHi JH Yang,
Thanks for the post.
Yes, the BW Connect (offline) feature should be coming to SAP PA.
