CREATE
PROCEDURE mySchema.MyProcedure(IN Param_1nvarchar(100):= '', IN Param_2 nvarchar(100) := '', [...])
Hi Edna,
Although you can implement it based on your script, but I think that it is not good solution, It will impact other thread or process, and reduce performance.
Anyway, if it is only test purpose, it is ok for your purpose; it maybe SAP HANA can implement it by own function or API in future, since then you can study or use it.
GOOD LUCK.

Hi Marcus,
Is it not possible for you to take the input parameter values anyway and then NOT use them in the procedure depending upon the value or logic ?
Regards,
Ravi
Hi Ravi,
That's how I realized it right now. I hoped that it will be possible because I have about 20 different values I'm entering in Param_1 as an action_type and depending on that the other params are required and I wouldn't like to "fullfil" the unused parameters with ''.
I now it from other databases (e.g. M$) that the parameters can be defined as optional or with default values.

Marcus
Hi Marcus,
If you have the SAP account manager associated with your SAP HANA project, then I'd suggest you to raise a "Feature Request". Depending on the business criticality of the required feature, your SAP account manager can then take it up with the proper development Manager / Team.

Hi Edna,
I am not sure if there is any 'sleep' or 'wait' function in HANA. However, if your requirement is
to make the procedure wait for a specified time(in seconds) then you can probably achieve that in the following way:
CREATE PROCEDURE PLEASE_SLEEP ( IN SLEEPING_TIME INTEGER, OUT WOKE_UP_AT TIME )
LANGUAGE SQLSCRIPT READS SQL DATA AS
V_TIME TIME;
V_TIME_TO_WAKE TIME;
BEGIN
V_TIME := CURRENT_TIME;
V_TIME_TO_WAKE < ADD_SECONDS ( TO_TIME( V_TIME ), SLEEPING_TIME );
WHILE V_TIME != V_TIME_TO_WAKE DO
V_TIME := CURRENT_TIME ;
END WHILE;
WOKE_UP_AT := V_TIME_TO_WAKE ;
END

Hi Preeti,
Can you please post the code. Ideally the variables which contain the resultset (except for var_out) need not be defined explicitly. There could be some syntax issue. Hence the code will help identify the issue.
Regards,
Ravi
Hi Preeti,
Can you please share the sample code which you are using? The syntax which you need to follow is
VAR_OUT= <<select statement>>
You can not write <<Select stament>> INTO VAR_OUT. Remeber, in calculation view you can perform only read operation and not write operations. Ultimately, your Script Based calculation view acts as a read-only procedure with VAR_OUT as a parameter.
Also, since VAR_OUT1 is a local variable, try using a colon before its name i.e. :VAR_OUT1 instead of VAR_OUT1.

Hi All,
I am currently working on a SAP HANA side car scenario. I have a Z report which needs to be read from SAP HANA database. I followed the following steps to identify the tables.
1. With the T-sode i identified the main program associated to the T-Code.
2. In SE80 selected the main program and identified the core tables, also identified the dependant tables
3. Replicated the tables to SAP HANA
4. Created the XML and loaded in SE38 to activate the scenario for SWT2DB
However when i run the trace in ST05 i still see that the tables are being read from SAP ECC. When i further analyse i see that there are certain function modules (SAP standard and Custom) within the main program specified in XML are being called.
Can you please tell me how do i handle such kind of scenarios for 100% read from SAP HANA and for faster reporting performance.
Regards
Nilesh Awaghan
Hi Nilesh,
For application acceleration, this statement applies which i extracted from the OSS note 1696402 content:
"Custom scenarios must not operate on SAP programs! Custom scenarios that affect SAP programs are regarded as modifications and will not be supported by SAP."
Maybe you have to leave it as it is unless you want to copy out all standard into Z namespaces?
Regards.

Dear Ankush,
I just joined this community and have read your very insightful posts. They are very informative.
I work in Logistics field, with experience in freight forwarding. I work for Maersk and Damco handling their freight forwarding, and now for Freight forwarder importing wine from all over the world to the US. I am now looking to boost my career and interested in a functional area of SAP. Just to give you a clue of what I am looking to do: I have managerial skills and looking to focus more on an area that will give me the best exposure to combine my experience and propel my career as a manager and consultant.
So far I have been advised to take SAP BI modules like MM, PP, SD, QA. However, I am a little confused when I read about HANA. I am kind of lost here. Based on my experience and interest, could you please, give me some advise on the way forward?
In anticipation,
Spencer
P/S:
I will ask same to one or two active poeple in this community to get their view too.

HI Srinivas Burra,
Thanks for your valuable guidance. I will start SAP BI/BW. After SAP BI/BW I will go with HANA.

Dear Nilesh,
When you use SLT, you use transaction LTR to create a new configuration.
After you click "OK" button then automatically Replication Control Tables(RS*) and DD* tables get replicated to HANA System.
After these tables are replicated successfully, HANA studio knows which tables are available in the source system
You can go to Data Provisioning tab in HANA Studio and you can check all the tables present in your Source System should be visible to you.
These tables should get replicated automatically. After this, you feel that there is need to load other tables, you can replicate them to HANA.
SLT is used only to replicate tables with atleast one key fields.
If you want to make changes in any of your existing tables then you can perform them using SLT

Hi Preeti,
Can you please try data preview on the projection in the Calc View (C3). It should call the underlying Calc view. It gets difficult to debug HANA views but check if the preview thing works for you. The earlier suggestion of inserting the data to a log table will not work as the SQL script Calc view is READ ONLY procedure.
Regards,
Ravi
Hey,
I got the result 
The input parameters should be passed in lower case ( i had defined it in upper case).
Thus, now the mapping is correct.
By comparing the "show log" such errors can be rectified.

Preeti
Great . Have fun with complex modeling. I am sure you must be aware that such a data model
Graphical Calc View (C3) based on Script based Calc View (C2) based on Graphical Calc view (C1) is not recommended. This will have impact on the performance.
Regards,
Ravi
Hey,
Yeah i do, but this is a complex requirement.
Hope for the best.
