Adding BW Modelling plugins in HANA Studio

Hello Experts,
I installed SAP HANA Studio in my local machine (outside C:Program Files, i.e in D Drive)
I followed 2 options to install BW Modelling Tools Plugin, both have been unsuccessful. Can some one please let me know what is missing.
I checked the pre-requisites mentioned in the installation document (http://help.sap.com/download/netweaver/bwmt/SAP_BW_Modeling_Tools_Installation_Guide_en.pdf) and my system has all the necessary ones.
Option 1
- Followed the instructions mentioned in the https://tools.hana.ondemand.com/
- HANA Studio --> Help --> Install New Software --> Provide the link https://tools.hana.ondemand.com/luna
- I get the below error
Unable to connect to repository https://tools.hana.ondemand.com/luna/content.xml
Connection to https://tools.hana.ondemand.com refused
Option 2
- Download latest patch from Service market place
- HANA Studio --> Help --> Install New Software --> Provide the Archive path
- Error message I get is below,
Missing requirement: BW Core UI 1.6.3 (com.sap.bw.core.ui 1.6.3) requires 'bundle com.sap.adt.destinations.ui 2.18.0' but it could not be found
Cannot satisfy dependency:
    From: BW DataStore UI 1.6.3 (com.sap.bw.datastore.ui 1.6.3)

If SAP could provide the HANA tools over just http:// instead of https:// then it would work under proxy conditions with the network connectivity option in eclipse set to "native" mode

Regarding Modeler in SAP Hana Studio

Hello Experts,
I am trying to connect to SAP HANA Trial System with my in house NSP System through Business Object Data Servicies.
I have completed the steps till configuring the import server in HANA studio now when click on "Import Link" Under Content, i am not getting "information modeler" option to get table structure.
Please help on this.
Please find the screenshot attached here.
Regards
Bhasin

Bhasin,
To import table structure, Click on SAP HANA Content --------> Selective Import of Metadata.
Once you click on above, it will ask you to mention Source connection details and type of import objects like tables & extractors.

SAP HANA studio plugin errors

Hello,
I am facing an plugin error in my Hana studio.
In the SAP HANA DEVELOPMENT perspective under the Repository tab, I am getting an error as,
"Plug-in com.sap.ndb.studio.dwb.team.ui was unable to load class com.sap.ndb.studio.dwb.team.ui.views.RepositoryBrowserView."
Please find the attached image and please help me to resolve this issue.
Thanks and Regards,
Vicky.

Hi Bhupender,
Its working fine now. But I don't know how it happens. I have just uninstalled Hana Studio server and client completely from my system including all the cache files.
1. Freshly installed the client and then server.
2. Then click Help->install new software->added the link->"https://tools.hana.ondemand.com/kepler"
3. Installed the plugins one by one and restarted the studio, accordingly. eg. first select the package "UI development Toolkit for HTML5" and download the plugins and restart the studio. next "SAP HANA Cloud Integration Tools", next "SAP HANA Cloud Platform Tools" and finally "SAP HANA Tools". Install "Modeling Tools for SAP BW powered by SAP HANA", if required.
Note: install "ABAP Development Tools for SAP Netweaver" only if it is necessary. Because I faced some plugin errors in Hana studio. Do not install eclipse plugins in Hana studio unnecessarily, because some plugins are vulnerable and it makes the studio, heavy.
The above procedures are working fine for me, till now. Now my studio is healthy and working as expected, without any plugin errors.
Thanks and Regards,
Vicky.

Model in HANA Studio or IDT

Hello Everyone,
We have a question on a scenerio/approach:
1. We have HANA and have SLT table replication
2. Do we model in HANA (with Calculation Views, Analytic Views, Attribute Views) Studio or model the relationship model directly in Information Design Tool?
We see all HANA documentation states Calculation/Analytic/Attribute views and mentions only IDT for creating the Universe. We don't see anywhere that you should create the model itself in HANA Studio or IDT. Is there a preferred approach/Best Practice?
Thank You!

Not very sure, what was the scenario that led BI expert author to that conclusion. Hope it was not one of those manufacutred lab scenarios.
Based on my past couple of projects on HANA, I know this for a fact by default Analytic View runs faster than physical tables. Client have always come up with same question and we have performed tests to get the right results. You can do this simple test, run SQL statement on both and monitor "core" status on your HANA box. You can see in case of SQL, only 1 core get utilized and in case of Analytic Views all cores utilization will go up.
Also on article key concept it says "SAP HANA Studio is the primary client tool used to manage SAP HANA and to create analytic views" which is not true. "SAP HANA Studio is the primary client tool used to manage SAP HANA and to create DATA MODELS (which can be attribute view, analytic view, Calculation View)

HANA Studio: Installation and usage

Hi,
I am currently retaking the the introduction course in the HANA development and wonder about the HANA studio GUI presented there.
Installation:
I see on the HANA Dev site that there is the Studio and the Client. Do I need both for installation? Or is in the studio already the client provided? If not, why are they separated? (instead of combined?)
Short: What is finally required for installation?
Plus in the intro on the second unit it is mentioned that I have to install as well some regi (???) client to access the HANA repositories. Is this still true? Also reg. config I see in the 1.0.80 version not the config-items as mentioned in the video. So, do I need them? resp. where to configure them?
Usage:
And last but not least I wonder about the statement that the System View is not much used. Better use the Project Explorer (or so). According to the video you could create your own files with the extensions you like and they will automatically associate with the proper editor. Is it really that in daily business the System View is hardly used? One creates his/her own files with appending the appropriate file ending?
roland

>Since everything is done in the System View (e.g. create an Analytic View) where is it stored?
It doesn't matter if you use the Systems View or the Project Explorer; the content is stored the same place/way on the server. When you save/commit in either tool the content is always stored in the HANA Repository. The HANA Repository is just a set of database tables (_SYS_REPO schema).
>Before activation and after?
You shouldn't really go picking around in the Repository database tables, but if you are curious before activation the content is stored in _SYS_REPO.INACTIVE_OBJECT and after activation in _SYS_REPO.ACTIVE_OBJECT.
>Therefore that I cannot switch forth and back with versions of a View, correct?
If you use the project explorer you can just access the version management from the History tab and restore or compare from any previous versions:
>When I follow your video, than I create first a package in the System, which will be updated in my repository view. Checkout, checkin, compare old vs. older version, etc. can only be done in the Repository View, correct?
You have to keep in mind that the Systems view was created before we really had a developer perspective in HANA Studio. It was design with Information Modeling (view creation) only in mind. Therefore in SPS05 when we added the developer perspective and many of the new development artifacts we introduced the repository and project explorer view. When you create a package via either tool - they are the same thing. However if you want to then work with a project or any of the newer development artifacts you must check out the project from the repository view and edit the objects via the project explorer.
>Is it also possible to check (resp. compare) if something in a folder structure was changed?
Changed by someone else after you checked it out? If so, you usually would just do another check out from the project. Otherwise you will find any conflicts when you activate.
>In SPS08 the project is automatically connected with the Team and I don't have to do anything further, like Share. Correct?
Correct. We continue to make usability enhancements and the automatic sharing of a project during the project creation wizard is one of those. We will continue with such enhancements in SPS09 - allowing the project creation wizard to also general some of the basic development artifacts (like xsapp and xsaccess) for you. You might be interested to know that we have a new openSAP course for HANA development starting at the beginning of October and it is based upon SPS08 and will showcase these improved workflows.
>For SPS08 is there an easier way to create the .xsaccess-file?
There is a new wizard that inserts a template content. It certainly shouldn't lock up your system to choose the wizard. Not sure why that would happen. You can also use the HANA Application Lifecycle Management tools and its Application Creation Wizard to generate the initial development objects with template content. For the complete list of all available options, please refer to the developers' guide on help.sap.com.
>Editor = at least two tabs, one with drop-down lists and one with text-files
Not within the Studio. After you have created the XSACCESS File it can be 'configured' via the XS Admin web interface. Not all options of the xsaccess file can be set from the XS Admin tool yet, however. Today you can mainly configure the authentication options.
In SPS09 we will extend these options to also include the CORS and Headers configuration:
>Does this mean, the files are automatically synced?
They are automatically committed upon any create or save operation. Originally in SPS05 you had to always choose to commit via a context menu. To improve the user experience we changed this to automatic. The manual commit menu option is still there (team->commit from the right mouse context menu). However it is really only needed if something goes wrong with the communication to the server or if you were developing offline and then want to force sync with the server at a later time.
>Since in the connection no specifics reg. server, port is provided I wonder how the magic is done
No magic. The XSJS code executes within the database. There is nothing for it to connect to since by its very definition it is always running within the database. The XS server isn't a separate application server connecting via JDBC or ODBC. The main point of XS is that it is a light weight application server fully embedded within the database.

Deleting C:\Users\<user name>\hdbstudio\.metadata folder works for me.
But I then need to re set up system connections, projects etc. It's a pain.
Fortunately it's becoming a rarer event for me now with later revisions.

HANA DB 1.00 Build 20 - Error import COPA Data with HANA STUDIO 1.00...

Hi,
Has anyone tried loading data records to HANA DB 1.00 Build 20 from the CTL files provided in     https://wiki.wdf.sap.corp/wiki/display/HANADemoenvironment/HowtoloadCOPAdata ?
It was work on HANA DB 1.00 Build 15 but not with New Build...
The procedure was exactly the same
The creation of Tables is done but i have this error with import data with each csv files:
Command with HANA Studio (Build 20):
                load from '/tmp/export/TCURT.ctl' threads 4 batch 1000;
Error:
               Could not execute 'load from '/tmp/export/TCURT.ctl' threads 4 batch 1000'
               SAP DBTech JDBC: [257]: sql syntax error: line 1 (at pos 3643214585)
I tried also: load from '/tmp/export/TCURT.ctl' -> same error...
We have all privileges on the tmp folder and files
I tried also to copy new data from source...
Do you have an idea?
Thanks for advance for help .
Best regards,

Hello,
LOAD TABLE command was not public - full syntax was never mentioned in any SAP guide on help.sap.com or Market Place (except SAP HANA Pocketbook-DRAFT). Therefore it is SAP internal syntax that can be changed anytime. And I guess this is what happened. Command is either deprecated or having different syntax.
If you need to import CVS file I would suggest to use official way - either IMPORT command (which was also not very public before but since SP03 it is mentioned in SQL Script Guide) or best using SAP HANA Studio import functionality (just be sure you use CVS as type of file).
You can find explanation of both ways in this blog:

Which ports are needed for SAP HANA Studio - HANA DB communication?

I want to connect SAP HANA Studio to a HANA instance. The HANA instance number is 40.
The SAP note 1592925 states that the ports 5$$13/5$$14 and 3$$15 should be open to allow communication between the HANA Studio and the HANA database. I even see the instance in the HANA Studio, but I cannot administrate it and the HANA studio gives this general "I don't want you to know what the error actually is" message:

Do I need to open any other ports to make HANA Studio work with HANA DB?
Regards,
Mark

Hi Mark,
The HANA Studio connects to HANA DB Instance with JDBC on port 3<Instance number>15.
For your HDB with Instance Number 40, the port would be 34015.
HANA Studio will automatically assign the JDBC port number when you assign the instance number when you add new system.
Looking at the error message that you posted:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-16 14:01:40.627
!MESSAGE [HDB hostname 40 (SYSTEM)] Error on refreshing system
It looks like the hostname entry was not entered correctly (you might have entered "hostname" value when adding the system in HANA Studio).
Here is an example of correct log entry on DCA database instance on hanasvr-01 server with Instance number 00:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-10 13:55:23.598
!MESSAGE [DCA hanasvr-01 00 (SYSTEM)]
You may want to delete and re-add your HDB instance in your HANA Studio.

Ferry

I don't have PAL schema in my HANA Studio

Hello all, I was studying and trying to solve some problems I'm having with Hana/Predictive Analysis. I was showing some error of insufficient privileges while trying to run some algorithms.
So then I was whatching the following video:
http://www.saphana.com/docs/DOC-3261
I don't have the schema named PAL in my HANA Studio, and I don't know what I was doing wrong, and couldn't find the solution anywhere.
And to make this troubleshooting , I need to set with the schema PAL.
PS: I already have the AFL package installed, and also the WRAPPER_GENERATOR (I didn't have wrapper generator in my Studio, so then I got it from a friend of mine, and executed without any kind of error.
So then I want to know:
Did I miss any steps in configuration? Or I need to do any other installation?

Go to the link below, download and install the program. Please read the instructions on the page.
http://culater.net/software/SIMBL/SIMBL.php
Then go to the link below, download and extract the program. Put the program in the plugins folder created above.
http://cooviewerzoom.web.fc2.com/colorfulsidebar.html
Force quit Finder and when you open a new Finder window, you should have color in the sidebar, although not across the top. You will need to Force quit Finder and open a new window after almost all restarts and startups.
Not perfect, but it works.
As an alternative, you can go to the link below and download the program. In the Lion Tweaks section, there is a tweak to restore color in the Finder sidebar, but I haven't tried it, so I don't know if it works.
Hope this helps.

How to add system to login using sid adm user in HANA Studio

Hi,
I have added SYSTEM user for my TEST system in HANA Studio. Now, I would like to add TEST system but using <sid>adm user.
It shows "The system cannot be reached. The logon data could not be used. Do you want to add the system anyway?".
May I know how to add TEST system using <sid>adm user?
Thank you.

You need Database user, not operating system user <sid>adm user.

How do I enable the Memory Overview in HANA Studio?

I read John's blog about the SPS7 features:
http://scn.sap.com/docs/DOC-49991#comment-467746
Now I wanted to see the Memory Overview myself. I granted the role sap.hana.admin.roles::Monitoring to user SYSTEM and opened the Memory Overview. This is what I get:
I cannot see the Memory Overview with HANA revision 70, 71 or 72.
I cannot see the Memory Overview with HANA Studio running on Linux or Windows.
I cannot see any entries in the tracefiles of the HANA database.
The same problem with Resource Utilization, I get a blank window.
The HANA database is up and running. Database, Client and Studio are revision 72.
What do I do wrong? It seems that I am not the only one affected.

Mark

Hi Mark,
Have a look at the loaded Delivery Units (DU) in your SAP HANA system. Is the HANA_ADMIN DU available?
Check if all the Delivery Units have been loaded
In SAP HANA Studio open the Modeler perspective and check the Delivery Unit.
In the menu Window => Open Perspective => Other select the SAP HANA Modeler perspective.
In the Quick Launch view navigate to Delivery Units. The following Delivery Units should be loaded by default.
HANA_ADMIN
HANA_IDE_CORE
HANA_TA_CONFIG
HANA_UI_INTEGRATION_CONTENT
HANA_UI_INTEGRATION_SVC
HANA_XS_BASE
HANA_XS_EDITOR
HANA_XS_FORMLOGIN
HANA_XS_IDE
HANA_XS_LM
HANA_XS_SQLCC
SAPUI5_1
If there are Delivery Units missing please load all Delivery Units using the Import option in the Quick Launch view. Click Import => SAP HANA Content => Delivery Unit
Select the files from the Server option.
Open the File drop-down menu and select the missing Delivery Units one by one.
To load the Delivery Unit press Finish and repeat this for all missing Delivery Units.

Pasting labels in HANA Studio

For my project I need to copy and paste hundreds of labels into Calculation Views that I'm creating. I can paste them one at a time, which will take a long time. Does anyone know of a way to paste a group of labels?

Hi Peter,
first of all, revision 25 is out also for HANA studio.
The display problem is yet unknown, but have you tried to get the perspectives to display via
