SAP HANA Limitations

Dear All,
Please let us know the maximum HANA DB Size and the recent Scale-out / Scalability recommendation from SAP .
Also please let us know the supportive document or SNOTE for the same.
Thanks
Arun R

Hi Arun,
To know how much memory has been used by different objects in HANA database, then the easier way is to use the TOTAL_SIZE_IN_MEMORY (along with main, Delta etc) from M_CS_TABLES. This would give you idea of how much memory has been used by objects which are partially or fully loaded to memory. Please note that it give 0 value for the objects which are available in the systm, but not yet loaded to the memory.
Please see this ote:
SAP HANA Database Size - In-Memory Business Data Management - SCN Wiki
Please see this forum:Where can I see the HANA database size? | SCN
For scalabilty:

Benefits/ Limitations when we use SAP HANA Extended and Standard products.

Hi All,
We are going to purchase SAP HANA media. Please let me know what are the benefits/ limitations when we use SAP HANA Extended and Standard products.
Thanks in Advance,
Vishall

Hello,
please check Master Guide (page 9 - chapter 1.6 Software Components)
https://service.sap.com/~sapidb/011000358700000604552011
There you can find edition comparison and detailed description.
To extract the short summary:
Platform edition = SAP HANA Database + Studio + Client + Host Agent + Information Composer
Enterprise edition = (Platform edition) + LT Replication Add-on (SLT) + LT Replication Server (SLT) + SAP BO Data Services
Enterprise extended edition = (Enterprise edition) + Sybase Adaptive Server Enterprise + Sybase Replication Server + Sybase Replication Server Agent + SAP HANA load controller
It depends on what licenses you already have and how do you intends to use HANA.
Platform edition = ETL via BO Data Services (you already have license for BO Data Services)
Enterprise edition = SLT and/or BO Data Services (including licenses)
Enterprise extended edition = all replication technologies

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...

Defining a recursive view in SAP HANA

Hi All,
Currently SAP HANA does not support defining recursive views as already mentioned in Tals discussion as per the following link:
Defining a recursive view in SAP HANA
I would like to ask again if this limitation is still exist in latest SAP HANA version or not?
Some background:
In our MDM product we can create a hierarchy tables which organizes information in a hierarchy where each record is related to a parent record and may also be related to sibling records and/or child records.
On other hands, MDM product generates database views that are saved as database queries representing MDM data. Currently HANA limitation prevents creating a database view on top of hierarchy database tables.
Lars Breddemann
Best regards,
Ahmad

Hi Ahmad,
just as I mentioned in BOM explosion there is a feature available in SAP HANA (column view type hierarchy aka hierarchy views) that is used (SAP-) internally.
AFAIK there are some ideas to make this available via SQL, but I don't know when or how this functionality will make it into the standard product.
Ruediger Karl the core HANA PM might be able to answer that.
Until then, you might be better off contacting SAP HANA development about possibly using hierarchy views for your development.

Creating Logic and modeling for SAP BW datasource in SAP HANA views and SLT

Hi to all,
I have small question.
We have BW system and SAP ECC as source system and to get data from SAP ECC source system we are using SAP ECC Standard data source.
Now we required to, create modeling in SAP HANA by use of HANA View and get data from SAP ECC source table via SLT.
So we can replicate same modeling,as we done in SAP BW system.
But my question is that, as SAP ECC standard data source hit multiple table and do run-time calculation, before sending to SAP BI.
How we can derives such calculation and logic, in our HANA studio, because as we know in SLT data transformation can be done in limited way also
in view we can not drive such logic via SQL script ?.
Is there any way we can do such modeling and logic in SAP HANA ?
or
is there any standard document for this type of case, which we can use ?
Note: We don't want to use SAP DS or DXC for data loading to HANA, as we want it in more real time.
Regards
Pavneet Rana

Thanks for reply,
As SLT is based on ABAP, so we can write complex logic in it.
But if we talk about SAP ECC standard data source, they have complex logic, based on multiple table.
So we need to write code from scratch in SLT to derive same result. but it will be huge time consuming , and required good ABAP skills, also it will lead to bug in code.
Also it will reduce the real time performance of SLT, due to complex logic.
Second option is procedure via SQL script, which is again huge effort in term if logic and can lead to error/bug in logic.
Does we have any other way or architecture to do this is very simple way, with high performance and less error issue.

SAP HANA: Differences in functionality concering side by side and ERP on HANA scenario

Dear all,
There are two ways to use HANA - on the one hand, I could use it as a main database (ERP on HANA) or, on the other hand, I use it as a secondary database next to a non-HANA database (side by side or "sidecar" solution) for selected matters.
Where are the limitations if I use the side by side solution only? Are there functionalities which I can not use in comparison to the ERP on HANA solution? Or offer both solutions the same functionality but only the way to use HANA is different?
Do you have any clue or any links concerning documentation - till now I wasn't able to find some..
Sincerely Yours
Zapp

Hi Zapp,
You can check the below thread for limitations in SideCar Scenario:
What are the limitations/challenges in HANA sidecar
In addition to these, you will not be able to use ABAP Proxies, ABAP managed database procedures and many other new functionalities that are being added to ECC on HANA.
If you use HANA as a sidecar, you would use it to accelerate only few transactions while with ECC on HANA, many standard transactions have been optimized to use the power of hana

SAP HANA ERP on AWS License Issue

Hi,
what licenses are available for the ERP version of SAP HANA for deployment on AWS? What is a MINISAP license? We tried to set up the ERP Trial from the SAP Cloud Appliance Library but can't access it via SAPGUI. Our expert says, the MINISAP license is valid for hosting on 64GB or less. Since we have chosen the smallest memory model available, it looks like we can't run it on AWS, which cannot be true. The system comes up, AWS charges money, but we can't access it. What did we do wrong? Seems like a few people here in this community use it already. I'd appreciate someone telling us how to fix this issue. We do not have problems with our BW instance which works well.
Best regards,
Chris

Hello Christian,
Trial systems in CAL come with a 30 day temporary license, already included. There is no need to install any other license into the system.
So your problem is, that you started an instance of the ERP Foundation Extension Trial System in CAL using your AWS account and you used the default settings in CAL (no changes to firewall or instance types. After 30 minutes or so the traffic light in the CAL UI under "INSTANCES" shows a green light - but you are still not able to connect with SAPGUI.
Is this correct? If so, there are two possible root causes:
1) your client machine is not in the same network as the ERP system. Could it be the case that your client machine is in a corporate network (behind a firewall) and the ERP system has been started on the internet?
2) the ERP on HANA system did not start automatically (which is very strange as everyone is using the same appliance). It could be the case that the AWS account has limits which prevent the instances to start up - but then CAL should give you an error message and it should NOT show green traffic lights in CAL.
Can you please check if you are affected by root cause 1).
If you can rule out 1) we need to investigate why 2) is happening. Can you please ssh into the HANA instance and fetch the dev_disp file from /usr/sap/<SID>/DVEBMGS00/work.

Hannes

Open HUB ( SAP BW ) to SAP HANA through DB Connection data loading , Delete data from table option is not working Please help any one from this forum

Issue:
I have SAP BW system and SAP HANA System
SAP BW to SAP HANA connecting through a DB Connection (named HANA)
Whenever I created any Open Hub as Destination like DB Table with the help of DB Connection, table will be created at HANA Schema level ( L_F50800_D )
Executed the Open Hub service without checking DELETING Data from table option
Data loaded with 16 Records from BW to HANA same
Second time again executed from BW to HANA now 32 records came ( it is going to append )
Executed the Open Hub service with checking DELETING Data from table option
Now am getting short Dump DBIF_RSQL_TABLE_KNOWN getting
If checking in SAP BW system tio SAP BW system it is working fine ..
will this option supports through DB Connection or not ?
Please follow the attachemnet along with this discussion and help me to resolve how ?
From
Santhosh Kumar

Hi Ramanjaneyulu ,
First of all thanks for the reply ,
Here the issue is At OH level ( Definition Level - DESTINATION TAB and FIELD DEFINITION )
in that there is check box i have selected already that is what my issue even though selected also
not performing the deletion from target level .
SAP BW - to SAP HANA via DBC connection
1. first time from BW suppose 16 records - Dtp Executed -loaded up to HANA - 16 same
2. second time again executed from BW - now hana side appaended means 16+16 = 32
3. so that i used to select the check box at OH level like Deleting data from table
4. Now excuted the DTP it throws an Short Dump - DBIF_RSQL_TABLE_KNOWN
Now please tell me how to resolve this ? will this option is applicable for HANA mean to say like , deleting data from table option ...
Thanks

Currency conversion error in SAP HANA

Hi,
I am new to SAP HANA and learning to create information views in HANA studio (SAP HANA SP6 on Cloudshare, HANA studio 1.0.68). I am trying to create a simple analytic view (on purchaseOrderItem table in SAP_HANA_EPM_DEMO sample database) to have GrossAmount converted to EUR.
I added a calculated column as follows:
When i click on "OK", i get error -
The check box “Calculate before aggregation” has been unchecked, because the definition of the calculated column contains measures with currency conversion, restricted measures or operands with input parameters. For such a calculated column the calculation is always done after the aggregation."
and checkbox "calculate before aggregation" get unchecked. See screenshot below:
Please suggest what could be reason? Thanks in advance.
Regards,
Amit

Hi Amit,
If you uncheck the "Calculate before aggregation" checkbox and activate the view, you will see in the generated log that a Calc scenario is created. (a view with /olap wrapper). Due to the calc scenario, the aggregation is defined as the default behavior for the KFs and hence the calculation cannot be done before aggregation.
By the way, I did not understand why do you need calculate before aggregation for a KF which is just a copy of another KF. If you need Gross amount in Local currency and EUR, then just perform the currency conversion without "Calculate before aggregation" checkbox. It will work.
Regards,
Ravi

SAP HANA XSODATA service (Service exception: column store error.)

Hi all,
i have a problem with my calculation view using xsodata service on it. (There's an input parameter called P
_SWERK)
In my calculation view, the data origin are two analytic views (on which the input parameter P_SWERK should be filter data at beginning of the sql script code).
First i read the analytic views with function CE_OLAP_VIEW and after i do a CE_PROJECTION function on them using the input parameter P_SWERK like a filter on field SWERK.
But when i run my application on browser the following error occurs :
<message xml:lang="en-US">Service exception: column store error.</message>
The link is this :
http://host:port/Project_DM/services/Test/TEST_ZIIG_PDM_CALC_VIEW_FINAL_service.xsodata/PianiDiManutenzioneParameters(P_SWERK='CO05')/Results
The service definition is :
service {
"EricssonItalgas/TEST_ZIIG_PDM_VIEW_FINAL.calculationview" as "PianiDiManutenzione" keys generate local "ID"
parameters via entity;
The SAP HANA AWS revision is 60.
Someone could you help me,please?
Thanks in advance.
Dario.

Hi Dario,
Does the calculation view work without xsodata service? From the URL, your XS project name should be Project_DM, but from the xsodata source, the project name is EricssonItalgas. I'm confused with this. Did you use rewrite_rules or?
Best regards,
Wenjun

Universe based on SAP HANA OLAP connection

Can I create universe based on SAP HANA OLAP connection ?
How can i access SAP HANA view which was created using OLAP connection in WEBI and Dashboard? It does not allow creating Universe on top of SAP HANA OLAP connection and give an error.
SAP BusinessObjects query and reporting applications can directly connect to OLAP SAP HANA connections. No universe is required, only a published OLAP SAP HANA connection.
Thanks

OLAP connection are only meant for tools that make use of OLAP connectivity only like BEx ..and HANA analytic views and calculated views are also treated as OLAP cubes for them..
So these connection is only available with analysis product like Analysis Office (which is meant to be used with Bex or OLAP cubes ) and Design studio which is again mainly built around OLAP paradigm..
You can not create a universe or Webi on Olap connection on HANA as of now.. However it could be like exposed in a future release of BO which is not public yet...

Issues while creating new user in SAP HANA

Hello Team
When i am trying to create a new user in SAP HANA studio i can see that there has been a new field added of DATA validity where there are two options a) Valid From and b)Valid Unitl . No matter whatever dates i give in this i got this error which creating the user . Status :- inactive
Reason :- outside validity period . PFA screen shot attached below . Please suggest what dates should be given in this field with some sample example .
Regards

Prag,
Try this. Execute the following in a SQL window started by a userid that has been granted the USER ADMIN system privilege:
ALTER USER BODS1 VALID FROM NOW UNTIL FOREVER;
You can use a date instead of FOREVER --- '2016-12-31 23:59'.
Good luck,
