Design Studio on HANA - HCP or AWS?

Hello community,
Has anyone had experience with hosting Design Studio on an XS engine in HCP?
We are looking to host Design studio on HANA but are not sure which solution to pick to host it.
This is our scenario:
Data source: XML files through an external webservice, weekly upload, less that 1GB of data
ETL Tool: Data services
DB: HANA
Reporting tool: Design Studio on HANA
Display: External website connecting to Design Studio Dashboard and displaying it within an iframe.
The solution will be public facing and therefore needs to be in a productive environment.
From what I have read, it seems possible on AWS. However I am not sure if it is possible with HCP.
Any experience on that?
Thanks

My only experience with this is on AWS - and looking at the PAM https://service.sap.com/~sapidb/012002523100018972812014E I would lean towards AWS; this is what we used during the OpenSAP course with SAP's Jim Rapp
Looking at this thread here HCP is possible with Design Studio but the poster gave up: Connect SAP Design Studio with HANA Cloud Platform | SCN

Abap users autorization for BO BI reports (made in Design Studio) on HANA data

Hello!
We are bit new to BO BI and Design Studio. Cauld you help us?
BO BI reports must represent SAP HANA data.
We have a lot of users in ERP with their roles.
We need accordingly restrict users access to certain values for group of users in given Data Source based on HANA Analytic or Calculation View.
For example, report must display only “A” Plant data for first group of users, for second group – only “B” Plant data.
Where should we mantain users (and give them roles) and what authorization use?
The best way for mantaining users is CUA on ERP for us.
BO BI supports SAP authorization and role mapping with it's own user groups with no probler.
But what about HANA? We didn't find any positive information about roles mapping and authorization in HANA.
It looks like we need to create all users and give them roles in HANA... Is it really so? How to synchronize HANA users and their authorization with ERP after this...
Thank you!

Hi - this is a question that is better for the HANA space. Do you want me to move it there?

Limitations while conected HANA universe to design studio

Hi All,
Previously i have created number of dashboard reports in Design Studio using BEx quires. Recently we moved to HANA database. From HANA we have universe connected to Design studio. Here we are facing some problems. It is not accepting huge data. when i tried to see the data in edit initial view, it is showing "data is too large ". looking to know about if any limitations and performance tuning while using HANA universe to Design Studio.
Kind Regards,
Sud.

Hi - please see the SAP Help page 68
http://help.sap.com/businessobject/product_guides/AAD14/en/ds14SP02_user_en.pdf
It says "Maximum Result Set The result set has a fixed limit of 5000 rows or 50000 data cells. If either limit is exceeded, no data is displayed"
Please also search SCN before posting per the SCN rules, as this has been asked before.
Thank you

Design Studio Standard Content in HANA Live Package

Hi,
Is there any documentation available for the list of SAP BO Design Studio Apps (also on how to install/integrate) that comes along with HANA Live Package
Is yes, please point us to the resources.
Thanks and Regards,
Ram

Hi,
On BW it does, but I'm afraid on Hana not. But if it is the same view (copied view, it does)
. So workarounds:
put everything in one view (if this is possible and is not influencing the perfomancy)
or use scripting:
        Global script varibale
             var_vendor string false false
        on startup
             var_vendor=DS_1.getVariableValueExt("HANA_VARIABLE_VENDOR");
             APPLICATION.doBackgroundProcessing();
        on background
             DS_3.setFilterExt("Vendor", var_vendor);

Conditions in Design Studio based on Hana

Hi,
I would like to create a Top 5 of Open Invoices, for example in my design studio (release 1.3) dashboard. But note that my datasource is Hana. Is this possible, what is the best wat to tackle this? Thanks for helping.

Hi Koen - to be honest, I don't have any best practices for dashboard design on HANA
I hope other community members will reply.
Since there are several Fall conferences coming up, it's a great question to ask there in person too.

Login Issues to SAP HANA from Design Studio

Hello All ,
I am pretty newbie here so the question might seem a bit elementary .We are trying to connect to our SAP HANA environment from Design studio .When we are pinging the XSEngine URL it is responding properly .But when we are trying to connect from Design Studio the following error occurs .
Here is the landscape we have designed so far :
HANA Server is installed .
BOXI 4.1 SP 5 server is installed .
HANA and BO servers are communicating through SSL .
Design Studio Add-on is installed on BO server .
When we tried to explore the path using HANA explorer we found the path mentioned in the error screen does not exist .
What we need to do to overcome this error ?
Regards,
Sourav Roy

Hi Sourav,
As mentioned by Karol, you have to deploy the DS-HANA Addon on your HANA System.

I can maybe help someone, maybe someone has tried something similar.
Thank you

hi,
I developed in Hana a calculation view with script, cfr stored procedure, this view I can use as a datasource in my SAP Design Studio. The loading of your datasource can be triggered by your button: set datasours load in script true, radiobutton event: DS_1.loaddatasource ();
Is this work around okay for you.

SAP Design Studio ODBC Driver Not Found error while creating HANA connection.

Hi,
While creating SAP HANA ODBC connection in Design Studio via Tools > Preference > Application Design > Backend Connection. I am getting error ODBC Driver Not Found. Error screen shot is attached.
My Design Studio version is 1.3 win 32 bit
My OS Win 7 64 bit
I have installed both HANA client 32 bit and 64 bit.
I have tried creating DSN ODBC connection via "C:\Windows\SysWOW64\odbcad32.exe" and via Control Panel > Administrative tools > Data Sources(ODBC). But it does not detect it either.
I am not sure what needs to change to let Design Studio know which HANA client driver to use.
Please help!.

Hi Rohit,
This seems to be a known bug with Design Studio. Please see the SAP Note below on this.

Conversion to Design Studio templates

Hi experts,
We are in the pre-study phase for the conversion of all 3.x BEx web templates (serveral hundreds of them) to either 7.x or BO e.g. Design Studio. Right now we are a bit concern regarding the gaps between 3.x and Design Studio at the moment, especially the RRI, bookmarking, personalization, broadcasting and so on. The question are:
If we choose to convert the 3.x templates to Design studio now, do we need to redo all the Design Studio templates again when these features are available at a later time? Or can the upcoming features be easily incorporated in the existing templates, for example, just mark the context menu options for RRI or personalization etc, just like the WAD does for all the underlying BEx queries?
Design Studio can access data from universe, from HANA and BEx query. Is it possible (maybe in the near future) to be able to change data source on which the query is based on just like the feature in WEBI? If so, the Design Studio templates are reusable, that is, no need to recreate templates again in the future in case there will be some major underlying data flows rebuilds from BW to HANA.
Thanks.

I don't think we have enough details from SAP yet to answer your conversion questions
Per the latest roadmap this is not in the next release:

Design Studio 1.3 - Concern

Hello Community,
With the release of Design studio 1.3 - the client expectation has gone up. There are few question that need to be addressed.
How feasible is Design Studio 1.3 over SAP Dashboard designer in adopting and in implementation ?
If the client is having only BW with them without any BI/BOBJ landscape in picture, can design studio 1.3 be a wiser choice over Dashboard designer? If Yes then why ?
In BW landscape what need to be done to get mobile access of design studio dashboard ?
Does Design studio support Data caching for offline report access and for faster report access - considering back-end as BW not running on SAP HANA ?
How complex is the coding with respect to custom development ?
Awaiting detailed answers.
Regards
Kumar

Kumar:
How feasible is Design Studio 1.3 over SAP Dashboard designer in adopting and in implementation ?
It depends on your requirements and needs. SAP has said many times this year if your data source is BW, HANA or a universe that Design Studio supports, start with Design Studio. Otherwise, per SAP, you have an automatic migration project.
Q: "If the client is having only BW with them without any BI/BOBJ landscape in picture, can design studio 1.3 be a wiser choice over Dashboard designer? If Yes then why ?"
A: How would they use Dashboard Designer in BW only? Where would they deploy? Not following.
See previous answer re: automatic migration project if you start with dashboarding on BW.
Q: In BW landscape what need to be done to get mobile access of design studio dashboard ?
A: BW only? Question came up at ASUG Annual Conference. In the SAP Enterprise portal there is a Design Studio iview and a portal mobility pack
Q: Does Design studio support Data caching for offline report access and for faster report access - considering back-end as BW not running on SAP HANA ?
A: It does not support offline today.
Q: How complex is coding?
A: I am not a coding expert, but I am able to apply SDK components. We heard customers at conference say they deploy without coding too. If you know JavaScript, you will be comfortable with Design Studio is what I have heard.

Performance related issues in design studio 1.2

Hi All,
Is there any best practices guide for development purpose in design studio?
I am facing performance issues when I increase the count of data sources (alias in my case) in my application merely from 2 to 3.
There is a considerable time lag in launching the application both locally and on the BI server.
My application is on HANA analytic views and going by its performance it should be fast.
Each and every data source I created contains not more that 1 or 2 dimensions and a single measure.
I am not able to understand why it is happening. Is it preferred to bring in all the data as one big data source? But in that case there is a limitation in selecting specific dimensions and measures for different components. Tool forces us to incorporate multiple data source alias!
Any views will be highly appreciated.
Best Regards,
Tanisha

Have you tried using background processing when adding the 3rd data source? See How to set up Background Processing in Design Studio
Design Studio 1.3 is coming out in Q2 2014 where planned HANA native connectivity is coming - see Figure 2 BI2014 Design Studio 1.3 Planned Updates | SCN > sounds like that might help performance.

Multiple Filters not working - Design Studio

Hello All,
I have seen some of the posts regarding this still no luck making my filter work. here is thh back ground. I have a calculation view created and it has company, Cost Centers, Count, Amt. My requirement is to display company codes and upon slection display appropriate cost centers. I am uning Design Studio 1.2
The calculation view is built on HANA Directly (side cart solution)
Created 2 data sources and 2 drop down (DROPDOWN_BUKRS, DROPDOWN_KOSTL)
       1. DS_BUKRS : BUKRS, KOUNT
       2. DS_KOSTL : BUKRS, KOSTL, KOUNT - Background filter - BUKRS
     On Startup - works fine
      DROPDOWN_BUKRS.setItems(DS_BUKRS.getMemberList("BUKRS", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 10));
     On Selection (DROPDOWN_BUKRS)
      DS_KOSTL.setFilterExt("BUKRS", DROPDOWN_BUKRS.getSelectedValue());   - Applying the selected BUKRS as filter to DS_KOSTL
      DROPDOWN_KOSTL.setItems(DS_KOSTL.getMemberList("KOSTL", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 1000));
When I select the company code first time it brings up some cost centers (Not Accurate, but brings some cost centers), When I change the company code I get an error 'All selections for dimnesion company codes are invalid and have been discared'
Quetions
1. Dynamic filter thru drop down box (Designedr 1.2) does it work with HANA version 1.0.7
2. how is the back ground filter works , that is defined in the Inial Edit view... (I am treating like a variable we use in BEx and passing teh value throu .setFilterExt)
Any help is appreciated.
Thanks,
Arthur.

Hi Arthur Samson
I would like to answer your Qn2 first.
How does background filter in Edit Initial view works -
If you wish to filter a dimension of the data source without being displayed in the data set, you can add that dimension in background filter.
For eg - If you have a table displaying Cost center and the amount. If you wish to filter this data set for a particular company code - add the company code in background filter.
Coming to Qn1.
Approach 1 - Try using single Data source.
eg -
DS_1 : BUKRS-> KOSTL-> KOUNT   ( follow this drill down row1->row2->row3)
On Startup -
      DROPDOWN_BUKRS.setItems(DS_1.getMemberList("BUKRS", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 10));
On selection of DROPDOWN_BUKRS
DS_1.setFilterExt("BUKRS", DROPDOWN_BUKRS.getSelectedValue());         DROPDOWN_KOSTL.setItems(DS_1.getMemberList("KOSTL", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 1000));
I believe this should work fine.
Approach 2
If you need two data source for some reason
try removing the BUKRS from back ground filter and add as first level of drill down (row 1 )
DS_KOSTL : BUKRS, KOSTL, KOUNT
Thanks

Design Studio vs SAPUI5

This thought has been bothering me and I just want to ask some experts what they think
I was wondering regarding the difference between creating a Dashboard/Application in Design Studio or direct using SAPUI5. I have create some native application using OData and consuming it in a SAPUI5 application using the MVC. I am current facing a requirement to create dashboard application using Design Studio and I am finding it difficult to create the relation between the both if there is such a thing. What I find really difficult is to not have a fool view of the HTML5 and script. Instead I am required to input varies scripts in different section in order to manage the events. Are there any plan to make DS more like a wysiwyg of the SAPUI5 which has a lot more elements and give direct visibility in an editor to manage properties and events. It just feels harder to use DS even though you can drag and drop elements. With SAPUI5 you just go the public SAPUI5 SDK check an UI element snippet code paste and go to the API and start fixing in the way you want.

Hi Carlos,
in the context you describe - access to HANA models in native HANA environment, I am sure you can come quite far also with Native UI5 on top of ODATA. The difference is - in this path you are on your own (which is sometime better, sometimes not so good)...
I know that there is a functionality of generating HANA Views based on BEx Queries, and this is improved in last SPs of 7.40 NW - nevertheless there will be still some restrictions. And this is the place where the difference starts:
BEx Query variable handling - here you would need to code some prompt dialog on your self, which is delivered in design studio
More complex functionality in BEx Queries - I do not know what is the delta, but I know there is some
Hierarchy handling - is HANA already handling all cases of hierarchies, even then - there are small differences in comparison to BW.
Visualization - I am not sure if you can get a real cross-tab component (perhaps you do not need it)
Context Menu - also something you have to make on your own
more others I do not have in my mind now...
Basically this is also the question - is the HANA functional scope for your scenarios comparable and acceptable to those which you are running in WAD? For some customers this answer is YES, for some NO. If yes, you can look at other reporting possibilities (eg. plain UI5). If no, I would recommend to go with Design Studio as many functions which are complex to develop are available already in the framework.
Personally, I am wandering about your WAD scenarios - as very often those are much more complex and bound to BW functionality which is already answering the question above to NO, but perhaps some can be answered to YES.
In practice, I think a mixed solution is a the key - you can try to move to native HANA as much as possible, this brings value - in terms of the stack clarity and also in terms of performance as there is nothing between HANA and UI (almost).
Btw, the statements above are as of TODAY - I am sure in few years those will be revised with new HANA releases and improvements in the HANA models.
this was my private view on this topic.
