Cannot make SAP HANA Business Layer IDT

Hi All,
PFA.
When I try to make an SAP HANA Business Layer in IDT, I do not see any of my views.
But views do exists and activated in HANA Studio.
Any ideas?
Ganesh

Hi..
Can you check do you have access for the views exists and activated in HANA
And also check whether server is up or not.

Cannot use SAP HANA Studio with SAP HANA One Instance

Hello together,
i try to make some tests in the SAP HANA environment. But i got the following error message each time:
An internal error occurred during: "Updating system 'HDB' ...".

I often read about different SAP HANA One and SAP HANA Studio versions.
Following information about the versions:
Studio: Version: 1.0.52
Hana One Instance 52.1
What could be the reason for getting this error message? I hope you can help me.
Thanks in advance.

Hi 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.

AWS - Cannot Terminate SAP HANA, developer edition 1.0 Rev 72

Hi,
yesterday I tried setting up an SAP HANA, developer edition 1.0 Rev 72 . However, the instance didn't get fully created, due to permissions issues with the AWS account I was using. So, I set up a new AWS account, and wanted to try again with the new AWS account.
However, I now have a "Prepared" instance that will not Terminate - if I try and terminate it, I get the following error:
Instance Operation Failed
Operation Terminate failed with message: AMAZON : You are not authorized to perform this operation.
Could you please manually delete this instance for me, because I am unable to move forward without being able to remove this instance.
Many thanks,
Ian

The first AWS account I used is a corporate AWS account. In this account my permissions were restricted, hence I don't think it ever fully prepared the instance.
The second AWS account I used, has a valid credit card attached, but, I can't switch it over to using this AWS account because I still have an Instance on the first account that I cannot, delete, remove, terminate. So until I can get rid of this broken instance, I can't do anything at all with the second AWS account.

Column Modification impact to Data foundation, Business layer and Data source in DS 1.2

Issue
An existing Business Layer that is consumed by a Data Source definition in Design Studio 1.2 Version: 12.0.2.201311041742 seems to invalidate the entire Data Source object after modification to the base tables DDL (data definition). Information Design Tool used is Information Design Tool 4.1, Build:14.1.1.1036, Version: 4.1 Support Pack 1.
Background
A modification was needed a base tables DDL (data definition). Specifically a column that stores the Date value as a varchar needed to update to a Date data type. After the modification was completed the Data Foundation and Business Layer in the Information Design Tool (IDT) needed
modification as well to reflect the updated column data type. Refreshing the Data Foundation and/or the Business Layer did not update the column Data Type. The step of dropping and re-inserting the updated table in the Data Foundation and subsequently the Business Layer updated
the expected columns Data Type as expected. All the existing Data Source definitions that were in use throughout the application (Design Studio) were invalidated causing the following error after the DDL update.
After rebuilding the Data Source definition in Design Studio, the issue was no longer there however, the existing Data Sources were still non-functional and were subsequently deleted.
In Sum
Is there another way to make changes to the base table(s) without negatively impacting the Data Foundation (IDT)àBusiness Layer (IDT)àData Source Definition (Design Studio) to the point where Data Sources on the Design Studio have to be redone preceded with similar effort at the IDT level? Is there a step(s) that I missed?
Any insight would be appriciated.
Regards,
Kris

Hi Kris - it looks like you have not downloaded the latest SP's for Design Studio 1.2
http://service.sap.com/sap/support/notes/1954748
I recall in late May SAP issues SP2, and earlier in the year they issued SP1 - could you apply both SP's, client-side and platform-side?

How do SAP BW tables translate in BOBJ IDT Business Layer?

How do SAP BW tables translate in BOBJ IDT Business Layer?
We understand that SAP BW stores data in tables. WHen we create BOBJ Universe, the table names are different from what we see in SAP BW . Can someone explain how the SAP BW tables get transitioned in BOBJ IDT with examples?

may be lets start fresh as i am lost now ,authentication and authorization are 2 different things right
1)authentication - I import the OBJECT role from SAP BW to BOBJ enterprise ,thats it a person can now authenticate SAP system
2)Authorization - how does this work ??
3)Rights - this are ONLY for BOBJ objects and has nothing to do with SAP BW objects or even SAP Data right ??
Thanks

BO 4.1 SP4 IDT - Not able to publish the Business layer onto the repository

Hi All,
We are facing issues while publishing the Universe onto the repository. Just to give a background of the issue, we are connecting to Oracle 9i database from BO 4.1 SP4 Information Design Tool. We have client tools installed on one VM server and BO enterprise server on the other VM . I have installed Oracle 11g client 32 bit on the client tools server and 64 bit on BO Enterprise server. I can create a session to the BO server from the IDT tool successfully I have even created a secured connection published on SAP BO server which means there are no port issues.
I create the data foundation and business layer on IDT. I have created a test one with only two simple tables and do an integrity check and it works fine. When I publish the Universe, after I click the Finish button, it just freezes and doesnt get anything back for a long time. After that period, the finish button gets enabled again and if I check on the server, Universe is not published.
Based on the KB 1586166 - How to enable tracing for BI4.x client applications I created two BO_Trace.ini file in the following directories:
C:\<user-dir>\.businessobjects\bimodeler_14\config
D:\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\conf
I was getting the trace files earlier as well but I just changed to see if something happens. I I have a hs_error_pid4198 file created on monday, but it seems to be a java environment error file. I am not sure if its related. The trace I see on the InformationDesignTool_ncs file is
trc file: "InformationDesignTool_ncs.trc", trc level: 1, release: "720"

Unable to create Business Layer on top of SAP BW OLAP Connection - BI 4.0

Friends,
Need an useful information, why can't we create a business layer on top of SAP BW OLAP connection which is built with BICS driver.
Today when i tried to create a business layer in IDT tool of BI 4.0 it didnt allow me to do so. Is it a s/w bug or am i following a wrong approach. I do know, we can create a .unx universe through relational connection. But i dont want that, please provide your input.
thanks,
Tilak

Hi,
this question has been asked many times before, so a search will reveal your answer.
as the warning told you when you tried the workflow in IDT - business layers aren't supported for Bics connections - i.e. you can't create a UNX ontop of Bex using BICS..
unfrotunately, it was a strategic product decision that seemingly can't be reversed/influenced, despite the inherent problems this causes.
There are lots of requests for this feature to be restored, on the Ideas Place here: https://cw.sdn.sap.com/cw/community/ideas/businessanalytics/sbosemanticlayer
Please search and Vote for one.

SAP NetWeaver Application Server ABAP & SAP Business Warehouse 7.4 SP8 on SAP HANA with ERP-System

Hello,
I have a running Instance of SAP NetWeaver Application Server ABAP & SAP Business Warehouse 7.4 SP8 on SAP HANA 1.0 SP8.
Here I have the minisap Licence of A4H.
When I get the Licence of ERP - do I have a fully ERP System on HANA ?
Or do I need a new Instance?

Hi Julia,
even if you or your company have an SAP license for ERP, you are legally not allowed to install the license key into the free offering it because you have accepted the terms and conditions of the trial/developer version.
If you want to use your own licenses, you would need to switch to the BYOL model where you bring in the license. For that you would need to purchase the SAP Cloud Appliance Library subscription. You get more details here (CAL FAQ - Business related questions ). To purchase the SAP Cloud Appliance Library subscription you would need to select the "Unlock full library" link on the top right corner of the Subscriptions screen on http://cal.sap.com.

Hannes

Cant find 'SAP NetWeaver Application Server ABAP & SAP Business Warehouse 7.4 SP8 on SAP HANA 1.0 SP8 [Developer Edition]'

I have successfull installed and been running 'SAP NetWeaver Application Server ABAP & SAP Business Warehouse 7.4 SP5 on SAP HANA 1.0 SP7 [Developer Edition]'
In my CAL-account I have seen that 'SAP NetWeaver Application Server ABAP & SAP Business Warehouse 7.4 SP8 on SAP HANA 1.0 SP8 [Developer Edition]' has become available.
Searching 'AWS Marketplace' with 'SAP HANA one' only brings up the version (SP5-7) I already have installed. How am I supposed to proceed to install the latest version (SP8-8)?

It wasn't removed. I and at least one other person reported it as abusive, because it contains just a link. I think after three reports, it's automatically hidden until the moderator rejects it permanently, or releases it. In this case, it was released.
Now, why did I report it? Well, the common view (obviously not shared by the moderator here), is that posts like that
1) Indicate the original poster (in this case you) could have searched for yourself to find the same link
2) Damage the site as a whole, as you end up with just a whole bundle of links from one place to another and no real content
3) Encourage posting of FAQ
My experience is that quite often the link isn't in fact relevant, and is just the result of the first hit of a keyword search using google. In this case it was relevant - but couldn't you have searched and found it yourself?
In the areas I moderate, posts that constitute a single link are rejected as a matter of course. See this blog for a full and complete discussion: Posting links and the jungle you end up in..

Free Trial SAP Business Warehouse 7.4 SP5 incl. SAP Business Objects BI 4.1 SP2 on SAP HANA 1.0 SP7

I have 2 questions:
Relating to accepting Terms and Conditions:
If I click <Try Now> for solution SAP Business Warehouse 7.4 SP5 incl. SAP Business Objects BI 4.1 SP2 on SAP HANA 1.0 SP7
and scroll down Terms and Conditions, the button <I Accept> remains disabled.
Other solutions like SAP HANA, developer edition 1.0 Rev 80 I can accept.
I have to mention, that so far I have no CAL account
Is it possible to choose another Amazon Instance Type - instead of the default one (r3.8xlarge with 244 GB RAM)?
I don't need 244 GB RAM on my BW on HANA server.
Thanks in advance.

Hi Harald,
ad 1) I assume that this is caused by a browser bug. Which browser (IE8, FF31, Lynx, ...) are you using on which operating system (Windows 7, SUSE Linux, ...)? Have you tried another browser to narrow down the possible root causes?
ad 2) The 244Gb instance is not only hosting HANA but also the ABAP/BW portion. In order to have all the demo scenarios of the BW on HANA Trial working it is required that the HANA server has 244GB of memory available. With less than 244Gb the demo scenarios wouldn't work and then there would be users complaining ;-)

How to make a BW Infoprovider for a SAP HANA Calculation-/Analytcial-View

Hi
I have got a BW 73 with a Hana.
How can I make a BW Infoprovider for a SAP HANA Calculation-/Analytcial-View in SAP BW ?
Thank You
Best Martin

Hi Rekha,
No need to do anything, just we need do migrate standard info cube to In-memory Optimized Info Cube. Once it is turned to In-Memory optimized Info Cube(We will have F table surrounded by master data tables) and no dimension tables in HANA.
F-tables is nothing but Analytic View in HANA and Master data tables are nothing but Attributes in HANA.
once you migrate to In-Memory Info Cube, your tables are ready in HANA and you can create different view.
have a look at the below videos.

Create a new dimension in business layer from Data source: text file on the web

Hi,
I have a text data source which is published every few hours that is accessible from a certain URL. I follow the instruction given in this http://scn.sap.com/docs/DOC-43144 - where it shows in great detail how to create the connection, data foundation as well as business layer to create a universe for this type of data.
All is well - I can use this universe in my WEBI doc and display the data.
However, in order for me to merge the data from this universe with another universe, I need to create new dimension based on the data from the text file. The new dimension value is simply the first 4 characters of the Subject found in the text file. The "Subject" dimension is of variant type: varchar.
Following the guide mentioned earlier, the connection is using SAP BO OpenConnectivity driver. And this driver limits severely the SQL statement that I can use to extract a substring of another string. Here's the screenshot of the SQl expression that I can use with this driver
After hours of searching, I cannot find any other connection driver for a text file that's published on a certain URL. The BO OpenConnection driver is the best that I could find.
So here are my problems
1. one of my data source is a text file published on a web
2. the only connection I can create does not allow me to create new dimension in the universe to create an important column "subject ID"
3. I can create the column in webi as a variable. But when I do so, I cannot merge it with existing dimension (webi not allowing to merge these 2 types). And without the merge, the flat file universe with my database universe can't be combined.
I'm using WEBI Rich client version 4.1 SP3 Patch 1. Build 14.1.3.1300
Is there any other idea that you can suggest without requiring to change the extracted data?
Thanks.
With warm regards

Hi Bala,
Were you able to find out a solution for the problem with uploading values for a variable from a text file on the web? I am confronted with the same request from users.
Thanks,

SAP HANA modelling Standalone

Hello Experts,
We are in the process of HANA Standalone implementation and design studio as reporting tool. When I am modeling, I did not figure out answers to some of the below questions .Below are the questions. Experts, please help.
Best way of modeling: The SAP HANA LIVE is completely built on calculation view; there are no Attribute and Analytical views. I have got different answer why there is only Calculation view and there are no Alaytic view and Attribute views. We are in SP7 latest version. This is a brand new HANA in top of non-SAP (DB2 source). What is the best way to model this scenario, meaning, can we model everything in the Calculation view’s like SAP HANA live or do you suggest using the standard attribute, analytical and calculation views to do the data model. Is SAP moving away from AV & AT to only calculation Views to simply the modeling approach?
Reporting: We are using the design studio as front end tool. Just for example, if we assume that we are
Using the BW, we bring all the data in to BW from different sources, build the cubes and use the bex query. Here in bex query we will be using the restricted key figures, calculated key figures calculations etc. From the reporting wise, we have the same requirements, calculations, RKF, CKF,Sum, Avg etc. if we are Using the design studio on top of standalone HANA, where do I need to implement all these calculations? Is it in different views? (From reporting perspective, if it’s BW system, I would have done all the calculations in BEx.)
Universe: If we are doing all the calculations in SAP HANA like RKF. CKF and other calculations , what is the point in having additional layer of universe , because the reporting compnets cam access the queries directly on views .In one of our POC , we found that the using universe affect performance.
Real time reporting: Our overall objective is to give a real time or close to real time reporting requirements, how data services can help, meaning I can schedule the data loads every 3 or 5 min to pull the data from source. If I am using the Data services, how soon I can get the data in HANA, I know it depends on the no of records and the transformations in between the systems & network speed. Assuming that I will schele the job every 2 min and it will take another 5 min to process the Data services job , is it fair to say the my information will be available on the BOBJ tools with in 10 min from the creation of the records.
Are there any new ETL capabilities included in SP7, I see some additional features included in SP7. Is some of the concepts discussed are still valid, because in SP7 we have star join concept.
Thanks

>> I haven't read any "official" guidance to move away from typical modeling approach, so I'd say stick with the usual approach- AT, then AV, then CA views. I was told that the reason for different approach with HANA Live was to simplify development for mass production of solutions.

>> I'm not a BW guy, but from a HANA perspective - implement them where they make the most sense. In some cases, this is obvious - restricted columns are only available in Analytic Views. Hard to provide more complex advice here - it depends on your scenario(s). Review your training materials, review SCN posts and you should start to develop a better idea of where to model particular requirements. (Most of the time in typical BI scenarios, requirements map nicely to straightforward modeling approaches such as Attribute/Analytic/Calculations Views. However, some situations such as slowly-changing dimensions, certain kinds of calculations (i.e. calc before aggregation with BODS as source - where calculation should be done in ETL logic) etc can be more complex. If you have specific scenarios that you're unsure about, post them here on SCN.
Universe: If we are doing all the calculations in SAP HANA like RKF. CKF and other calculations , what is the point in having additional layer of universe , because the reporting compnets cam access the queries directly on views .In one of our POC , we found that the using universe affect performance.
>>> Depends on what you're doing. Universe generates SQL just like front-end tools, so bad performance implies bad modeling. Generally speaking - universes *can* create more autonomous reporting architecture. But if your scenario doesn't require it - then by all means, avoid the additional layer if there's no added value.
Real time reporting: Our overall objective is to give a real time or close to real time reporting requirements, how data services can help, meaning I can schedule the data loads every 3 or 5 min to pull the data from source. If I am using the Data services, how soon I can get the data in HANA, I know it depends on the no of records and the transformations in between the systems & network speed.

>>> Not exactly sure what your question here is. Your limits on BODS are the same as with any other target system - doesn't depend on HANA. The second the record(s) are committed to HANA, they are available. They may be in delta storage, but they're available. You just need to work out how often to schedule BODS - and if your jobs are taking 5 minutes to run, but you're scheduling executions every 2 minutes, you're going to run into problems...
