Career with HANA

Hi Friends,
I am an ABAP Developer and I have just completed my Training in HANA and I am working on my Certification. Is it good for me to have knoweldge with BW/BI and BO. With BO I am now done my training with the reporting on HANA. Kindly input your thoughts and suggestions. How should I take my route to be an efficient person in HANA. I have never worked hands on with BW/BI. So need thoughts from experts. Is ter any good book to self start on BW/BI ? If yes then do provide me the details

Hello Radhika,
First of all you are on the correct track.
ABAP composed with HANA is already so much to learn and work with. SAP BW will be required when in project where SAP BW on HANA is required. Even for BO on HANA is required.
Generally the correct route is considered as
BI/BW=> BO=> HANA
But as you have covered ABAP and finished off learning HANA, the route has been a changed one for you. But still learning BI/BW will be a good approach even though may not be so necessary at the moment. I believe you have not worked with HANA either as you mentioned not with BI/BW yet.
So correct approach can be get started with HANA developments and spend enough time and capture the concepts. As ABAP is there with you, developments in HANA will somewhat will be easy to master. So as the journey progresses you can add flavours of SAP BW alongside your working on various projects.
So far as BW materials are concerned, I have all my certification materials which I have no issues to share with you. Click my name and click follow tab here in SCN so as to send direct messages. We may share contact Ids to make it possible.
Hope the piece of information helps !!
regards,

In sap bw with hana, How exactly the performance is improved ?

By replacing oracle db with hana , are we installing new processors as well. Or is the performance we get is purely because of columnar storage ?

Hi Mohd,
This is a good question. Just replacing the DB or columnar store doesn't help.
If HANA DB is just a data base on memory then everyone can just add more memory for existing DB or columnar store then most DB already offer columnar store ( Like IBM DB2 Blu Accelerator or MS Sql columnar, etc)
It is a combination factor of HANA DB which optimised for both read and write operations along columnar store and data compression. In case of HANA DB sap is trying to push most of the process to database.
All new BW modeling techniques ( ADSO or New Composite Provider) will work only with HANA DB.
General points why BW on HANA is more efficient
1) No DIM ID in cube
2) Change log tables can be converted into views ( optional )
3) DSO Activation Pushed to DB
4) Transformation Pushed to DB if no ABAP routines.
5) No need of index for cubes
6) Aggregations is no more required.
Thanks,
Shakthi Raj Natarajan.

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:

Be Careful With Apple Authorised Services in Russia

Dear Society,
I have bad experience with contacting one of authorised services which is published in Apple web site. It is a company called "Service.OK" and situated in Zelenograd in particular. My MacBook Air 2,5 years old got to have a problem with a screen after few drops of wine leak inside from the vent area where black panel is situated and served for monitor and keyboard panels junction. I have not expected the problem with the laptop because the glass of wine feltdown far away from the place it is situated however it was lying upside down and closed. So drops still most probably go inside. After certain period of time I switched it on and started working. Suddenly the screen goes blue and later fade away. Next day I brougt it to the address where this "Service.OK" is situated for diagnosis.
In a week I got a call from the service where they offered to repair for about 7500 RUR in cleaning the oxidation that was caused by the wine. I gave my permit for this operation. After a week time I got a new call from the service and they informed me that they were unsuccsesful with reparing it and my laptop requires to change the whole screen panel. The price of it was 23000 RUR. This time I was angree that this company is not able to do right diagnosis and I do not know what to expect later even if changing the screen panel will be unsufficient for them. I asked them to stop any actions and return the laptop back to me. I promise to compensate thier effort for diagnosis though. The service said that I can pick up it after receiving sms notification.
13 days left and I got this sms notification. I was back from the business trip and came there in 5 days. And (what a surprise!!!) I got another display panel assembled to the keybord panel with my serial number. I am 100% sure that it is not mine from the scratches I had on the top/screen panel. I rejected to take it and called to
(A) Service.OK contact number claiming that and
(B) Apple support contact number desribing the problem.
(A) Service.OK informed me that my laptop was not delivered to them. The company which is operating on the address where Service.OK is shown in Apple web-site is no longer their representative point. It is another company as far as I unvestigated. However I got
(1) a receipt with Service.OK web address reference,
(2) Service.OK web site contained an information about my laptop being received and reviewed and
(3) Service.OK point shown on their web site is the same where I gave my laptop.
(B) Apple support specialist Natalia was responsible to communicate with me about my claim. She promised to report about this problem to higher department responsible for servises authorisation in Apple. However I was really dissapointed that no actions toward Service.OK was made by Apple. It is still on the authorised services list on the same address where I gave my laptop. She can only sorry to me because Apple has no legal company in Russia to handle this situation and thier company is just for providing support.
So I have a situation that neither Apple nor Service.OK are not willing to take responsibility that my laptop does not received qualified diagnosis under Apple authorisation and additionally its parts were changed while this diagnosis.
I am now consulting with lawer in order to investigate opportunity to claim about this problem to either Service.OK or company that issued an official receipt (or even propably to Apple) in the court.
Thus I would like to underline following statements:
- Be carefull with authorised service centers in Russia. Apple seems to do not care about what is going on there.
- Never deal with point in Zelenograd and be careful with other Service.OK points.
- Know your laptop serial numbers before giving it to diagnosis otherwise it is unable to prove own position.
I will be thankful if anybody from society had such problem in the past and may give any advice. Any opinions are welcome.
Thanks
Dimitri

External views with HANA as secundary database

Hi,
internally we have since some time a discussion on whether one can make external views in ABAP when HANA is your secondary database. According to the documentation it is not possible, but apparently the HANA-versions of Financial transactions do use them. These transactions are SAP standard transactions. It is difficult to convince our users/developers that this is not possible, when they see it is used in SAP standard ...
We do not get any clear answer to this problem. Also not from our consultants. The only remaining possibility seems to sketch a possible solution and ask you all some questions and make some statements to see if I am right.
I think this little sketch shows the landscape you need to make all this possible:
One cannot create an external view in Ecipse (ABAP in …) when you have HANA as a secondary database.
External views can only be created using AIE, not in SE11 in the GUI.
When these external views are created – using the described process – these views cannot even be displayed in the AIE when having HANA as a secondary database.
This is the message we get:
If you want to create an external view, you need a ‘landscape’ where HANA is you primary database. This means a supplementary R/3-ABAP and a supplementary HANA database, where all necessary tables do exist.
You have to develop you HANA artefacts (attribute views, analytical views, calculation views, …) in this separate landscape.
If you want to call them using external views, you have to do your developments here!
Based on these views you create external views in the AIE on this separate landscape. This way they exist in the ABAP dictionary in this system.
The name of the HANA-artefact and the external view in the ABAP dictionary have to be identical.
You copy the HANA artefacts to you first HANA (where you use it as secondary database). Copy, transport, … whatever.
You copy/transport your external view to your first ABAP dictionary.
Now you can use it in a SELECT with CONNECTION(“to_2ndary_hana”).
Is this correct? Or do I still miss something?
Thanks for any reaction.
Regard.
Kris

Hi Kris,
except for "The name of the HANA-artefact and the external view in the ABAP dictionary have to be identical" all you points above are valid.
Let me say a couple of words about the external views, especially those delivered by SAP.
Assume you have a development system landscape like DEH (development system with HANA as primary DB), DEO (development system with another DB), QCS (quality system, doesn't matter which DB but receiving the consolidated transports of DEH and DEO), PDS (productive system with non-HANA as primary DB and a secondary DB connection to HANA).
In this heterogeneous landscape you can create HANA content in DEH (respectively in the HANA underlying DEH) and external views via the ABAP Development Tools. You can transport the HANA content (e.g. via the HANA Transport Container) as well as the external views (and database procedure proxies) to the QCS system. The dictionary content, i.e. external views and database procedure proxies are active - otherwise the import/activation will fail - but you cannot consume them. Consumption of external views in the QCS system will lead to runtime exceptions as the underlying HANA artefacts are not accessible. However, since all the dictionary content exists, i.e. external views, database procedures, and the HANA transport container and all of them are active, you can further transport them to the productive system PDS. Once the external view is available in PDS and the HANA artefacts are available in the "side-car HANA" (assuming for simplicity you just use the connection to the DEH HANA), you can consume the external view respectively the underlying HANA view via OpenSQL in conjunction with the CONNECTION statement.
The described procedure explains how SAP has been able to deliver external views. In our system landscape, we have development systems on HANA as well as systems using non-HANA as primary database - how exactly depends on the product etc. So once the colleagues developed their HANA views and created the external views on such a development system on HANA, we can deliver external views. You can consume these external views:
in a system using HANA as primary database (assuming of course you have also received the correct HANA content and everything has been activated properly)
in a system using HANA as secondary database and using the CONNECTION statement in Open SQL
In scenario 1. you are able to create external views yourself via the ABAP Development Tools, while in the second scenario you can neither view nor maintain the external view.
For database procedure proxies, there is a method to create the DB procedure proxies programatically (see http://scn.sap.com/thread/3498161).
Hope this clarifies your questions,
Cheers,
Jasmin

How to get Maintenance_HDB certificate for BW Powered With HANA system.

Hi,
We need to install Maintenance_HDB license in order to install BI -CONT addon component on our newly installed BW Powered With HANA system. But we could not get Maintenance_HDB license, as we are able to get only Maintenance_ADA License for our system.
The main clarification required here is while adding a new entry in SMP (Service Market Place) of BW Powered By HANA system, what is the product that needs to selected in order to get HANA as database. We did selected Netweaver 7.3 for which we were actually made to select MAXDB as database but not HANA.
Thanks & Regards,
Pavan Indrakumar

Well even though it says your customer number is not authorized for HANA DATABASE license for BW, we can add HANA as database product under Netweaver 7.3 and proceed requesting for Maintenace License.
Not sure about the exact criteria behind the license provisioning.

Okay my phone was working just fine and I locked it and went to unlock it and now it just sits on the black screen it wont even show the lock screen I dont know what to do but I am very careful with my phone anyone know how to fix it? Plz and thank you!

Okay my phone was working just fine and I went to unlock it and it wont show the lock screen it just remains black please if anyone can help me fix it it will be much appreciated, I am very careful with my phone so I dont know why its acting like this.

I'm glad to hear that they replaced your phone. Any experience I have had with Apple customer service and/or Genius bar has been extremely positive. While I have had positive outcomes from trouble with other phones in the past, they are not as quick and friendly. I had a Motorola phone and a Samsung phone go bad several years ago and warranty work through AT&T required that I wait for a replacement unit and then mail back the original unit to keep from being charged for the device. This usually meant almost a week without a phone. Nice to walk into Apple and walk out with a replacement device. Enjoy your phone.

System Refresh with HANA & HANA live (side-car) data

In a scenario where HANA live co-exists with HANA DB (aka side-car approach), trying to understand the impact of system refreshes to HANA Live content. Is there a method to choose only HANA DB specific data for the refresh i.e. excluding HANA Live data? If we use the backup/restore method to refresh QA from PROD it will bring Prod data over for HANA Live too. Is there a way to export QA HANA Live data prior to the refresh and re-import it post DB refresh?

Sorry I thought it was clear, let me explain.
HANA with SLT, is a replica copy of ECC tables. If you copy HANA Prod back to QA then SLT will no longer be operational.
You could re-enable SLT but you would have to re-initiate replication which would wipe out all the HANA tables, thereby making your system copy worthless.
If you don't re-enable SLT then you won't be able to do any testing or any table changes into QA.
So really there is no choice, you need to copy ERP Prod and HANA Prod, or just copy ERP Prod and re-initiate replication.

Career with BI/BW

Hi,
Sorry. This is a non general question.
I am presently in UK.
I have experience of 8+ years in other technologies & ERP. I wish to pursure career with BI/BW.
I am trying for an online course with dummy assignments to learn SAP BI/BW. My question is:-
Is it worth going for a training & looking for a job in this area?
Does it require experience to get a job in this line?
Do companies ask for certifications?
I am getting an online course from India @ 13k INR. Kindly advise if it is worth going for a career change.
Thanks,

Hi Alok,
Thanks for all your very valuable inputs, thats been very helpful to me.
I do not have an experience with SAP. I have worked with a Microsoft ERP for 5+ yrs in functional & technical both plus 3+ yrs in other technologies as Sr. Engineer. Currently my role is more a functional being a Sr. Consultant.
I wish to switch over to SAP functional modules or SAP BI/BW. I do possess a good functional knowledge in almost all modules but not with SAP. But i do not know if this experience will really help with SAP.
Are there any good online courses available in this thread? If yes what will be the fees? (If anyone is aware...)
I know the fees at the authorized training centers for any functional module is very costly(i thnk arnd 1.5 - 2.5 lakhs).
But are the other institutes worth going for trainings?
Can a person without prior SAP experience directly go in for SAP certifications?
Thanks in advance,
Best regards,

HANA Studio connection with HANA server in HANA One (Rev 56 and up)

Dear HANA One Customers,
You must be aware of our latest HANA One release with HANA SP6 (blog: The specified item was not found. Once you launch a new instance using HANA One Rev 52.1, you can upgrade your instance to HANA Rev 56 or HANA Rev 62. You can do it in steps (Rev 52 -> Rev 56 -> Rev 62) or do directly (Rev 52 -> Rev 62). By the way, Rev 62 is the first HANA 1.0 SP6 release in HANA One. As we recommended, if you upgrade HANA Version to 56 or 62, please upgrade your HANA Studio and HANA Client to the corresponding version.
If you upgrade to either Rev 56 or Rev 62, you don't need to add any entry to C:\Windows\System32\drivers\etc\hosts to connect HANA Studio to use all the functionality of HANA Studio with HANA in cloud. While HANA One's add-on manager, upgrades. it makes a change in one configuration file (global.ini) for public_hostname_resolution.
However, if you change IP of your HANA One instance, you need to update this parameter which is described in the Quick Start Guide. The steps are summarized as:
In the Administration editor of HANA Studio,
Choose the Configuration tab. A list of all configuration files appears.
Expand the global.ini configuration file
Select the section public_hostname_resolution
Choose Next and enter the values map_hanaserver in the Key field and your IP or public DNS in the Value field.
For example, set the values as Key: map_hanaserver, Value: xx.xx.xx.xx if you use an IP address including an Elastic IP. If you use DNS as the value it could be ec2-xx-xx-xx-xx.compute-1.amazonaws.com
With this new feature, the same HANA Studio can connect to many HANA One instances at the same time which was not possible earlier prior to Rev 56.
Thanks,
Swapan

Yes Aleksandr
I think you are right.
After doing many installation of HANA Server in differrent AWS instances it didn't work for me.
But when I installed the HANA Studio on another machine with more RAM it worked.
I think we have to install HANA Studio on another AWS instance with 16 GB RAM to make it run smoothly.
Thanks & Regards

Migrating Backend Database for BW and ECC with HANA

Hi Guys,
I have been going through the blogs and its fantastic information but i couldnt find anything related to " how to migrate BW or ECC backend database with HANA DB. As per my information the HANA has its own DB which is called "IMDB", so if we have oracle or SQL server at the back end for BW or ECC , how can we migrate to HANA.
Plus are there any tools that are available for migration.
Thanks In Advance.
Sheikh Hassan Ayub

First, let's be clear:
1/ Accordingly to announced SAP plans the ramp-up (restricted shipment) of BW-on-HANA installations will start on the 7th of November 2011.
2/ There are no firm plans for ECC-on-HANA availability yet - so this is out of scope for current discussion.
"IMDB" is the name from the past. Now HANA's database is called "HANA database" but you will still find references to "SAP In-memory DB" in documentation etc.
Migration of BW from let's say Oracle to HANA db will be following standard OS/DB migration process - similar to the way you would migrate Oracle DB to DB2: export of the source and then import to the target server. Exactly the same tools.
Regards,
-Vitaliy

PA with HANA requirements

Hello,
Imagine I have a HANA Server (256 GB) running a development instance of Business Suite on HANA (or S4/HANA). If I want to do some predictive modelling, can I use that same DB, or do I need a separated machine?
I tried to find hardware specifications for HANA PA but didn't find any. This for demos, not production, what size do I need? 128 GB?
Thanks, sorry if this is available but I didn't find.

Hello Joao,
I fear that question is difficult to answer on SCN, because the answer is very specific to each individual customer.
Could you please reach out to your Account Executive to verify that this use case is covered by your licencing? Your local SAP team can also comment more specificly to your architecture whether / how this can be supported. Especially with HANA SP9 there are now a number of ways to deploy multiple uses cases. But it is quite specific in which combinations of use cases are supported.
Many Greetings
Andreas
