Hi All,

we try to use the oData services for data exchange between the SAP UI and backend.

We know the solutions if we would be use RESTful only.

But the OData usage is still new for us, and we don't know what are the best practices in SAP UI / oData environment.

THE USE CASE

1. We want, that a user entering in the input field one or more countries .
2. After that the list of countries to be displayed.
3. The user can select specific countries and request more information for those countries.
4. In the ffurther list should be displayed details related to selected countries.

In RESTful only solution would ausehen as follows:

The user enters a search term.

The keyword is sent to the back-end controller.

The back-end controller sends these input parameters to the database on.

In response gets front-end JSON array with JSON Objects where countryID and country name is.

The JSON array is set in the UI list. Each element contains contryName and countryID. Therefore you know what are selected for elements.

The countryIDs are sent back to back .....

How can this by using oData services solve?

I've read that via call of odata serive withGET with &filter, the amount of results will be limited. I have also read about the CalculationView + Stored Procedure with Input Parameters ...

Thanks in Advance,

Udo

Hi Experts,

I created on procedure with out output table parameter with "WITH RESULT VIEW" on the same.

When I am executing the procedure in the console , I am getting the result as expected. Can I expose the service as OData via XSODATA ? Or do I need to create XSJS or Scripted Calc View ? Procedure is taking one mandatory input parameter .

Regards

Hi experts,

I'm looking for a sample, how to use UDFs (table function) within calc views.

I try to use an udf table function within a calculation view as a datasource but don't get it activated.

error:

Repository: Encountered an error in repository runtime extension;Model inconsistency. Could not derive table type for variable "_SYS_SS2_RETURN_VAR_" (SQL error: index out of bounds: PersistVector index out of bound)

If I select the udf directly in a sql statement it works as expected.

select * from "TBASE_PUBLIC"."development......functions::get_labor_by_patid"(3161,'','');

The table type is a cds .hdbdd artifact. Could this be a reason for the error?

Thanks for your help!

Hi,

So I would like to get all tables from a schema. What I found on the SCN:

SELECT TABLE_NAME AS "Table" FROM  M_CS_TABLES WHERE SCHEMA_NAME = 'your schema name';

Now I would like to extend this to the security concept.

So if I have tables

A1

B2

C3

and User1 has Access to tables A1 and C3.

If User1 would run the query, he would only get A1 and C3 as a result, not B2 though.

Is that even possible? Any idea of a workaround?

Hello,

I recently wanted to try System Replication between a SPS 10 (SLES 11 SP2) (SiteA) and  SPS 11  (SLES 12) (SiteB).

I tried to follow the steps described in the "How to System Replication" Guide. But i always get the same error message after trying to register the secondary Site:

checking for inactive nameserver ...

nameserver bn-sap09t:30001 not responding.

collecting information ...

error: unable to contact primary site; to 172.18.2.24:30102; original error: ssl: internal error,location=172.18.2.24:30102;

I thought that this was an problem with the communication between the two systems, so i deactivated both firewalls. But nothing changed.

SiteA:

System Replication State

~~~~~~~~~~~~~~~~~~~~~~~~

mode: primary

site id: 1

site name: SiteA

Host Mappings:

SiteB:

~~~~~~~~~~~~~~~~~~~~~~~~

I am migrating PL/SQL code to HANA procedure. I have a update query with WHERE CURRENT OF c_temp(c_temp is a cursor). When I am running it in HANA, it's trowing the below error.

sql syntax error: incorrect syntax near "OF": line 261 col 22 (at pos 8940).

I have an Analytical View (we'll call it AN_ONE) that currently uses an Attribute View (AT_ONE).

After making a change to AT_ONE by adding a new column and Activating it, the changes that I have made do not reflect on my Analytical View (AN_ONE).

Is there a way to refresh the Analytical View (AN_ONE) to reflect the changes I have made to my Attribute View (AT_ONE) without getting rid of it and reloading it?

Thanks!

Hello Experts,

I had a unique customer question the other day and I am not sure if it can be done or the best approach to take. Any advice would be much appreciated.

Background: The customer has built a development web application which uses multiple HANA views to display different reports used by management. The views are built on tables which are updated daily.

Problem: While demoing the reports from week to week to management they want to be able to display the same output on their application even if the underlying data had been changed. So basically they want to be able to cache all the view outputs from today and display them weeks from now, even though the underlying data changes. I have read about Caching in HANA and I believe its purpose to be for more for enhancing query execution time for complex querries rather than taking snapshots of the views. After the demo period is over they won't have a need for this and will go back to their live views.

Any ideas on what can be done here?

Thanks,

Connor

I want to perform a to_date function on a string e.g 9906 to get the output as 199906. This is possible in Oracle using TO_DATE('9906',''RRMM''). But in HANA I didn't find such option. While using YYMM I'm getting the output as 209906 which is not desirable. Please suggest.

HI All.

I am pretty new to XS , I am trying to create an ODATA service from a calculation view . But whenever I try to activate the service I get the following error

"Missing specification of keys for view "demo::CV_PASS1".

Thanks,

  Hi All,

is there any way that we can view  SQL statement for a cal view (graphical ) in HANA

Thanks

Thank you in advance.

I am developing an app on HCP and I have given anonymous user access.

But as per my requirement, I can set the "authentication" to null in xsaccess file as I need the user details from the session.

Hence, I have to enable SSO.

Enabling SSO is barring the users from accessing the xsodata giving the error as "Insufficient privilege".

So I want to know that is it possible to enable SSO and still provide anonymous access?

Hi Experts,

I have a requirement in HANA where in I have data like below.

I need to convert to as below.

Can I achieve it in HANA SQL?

In Data services we can achieve, can we achieve it in HANA, without going into Procedure logic. As I have to bring the First table data virtually from Teradata.

How to split a comma separated String into multiple rows via word_ext - Enterprise Information Management - SCN Wiki

Please help.

Greetings...

Not able to convert in SQL Script

Hello everyone. I hope you're good,

I have a question, I'm trying to access to SAP HANA LIve Browser, but when I put my credentials and press "Login"  nothing happens, it gets stuck in the main page,

the URL I'm using is http://<server>:<port>/sap/hba/explorer and my user in HANA have the sap.hba.explorer.roles::Developer role assigned,

Am I missing something?

Thanks for your help.

Hi Experts,

                  Can you let me know which HANA Live view (CAR HANA Live content) has the data related to SAP Table EINA (Purchasing info record) ??

                 which is desperately needed for one of the master view that we need, as we couldnt query ECC tables directly.

Regards,

Prasana

Hello team,

We are currently using 64GB system in AWS and we are running out of memory, so we decided to migrate to 128 GB.

What is the best/faster way to migrate?

Dear SCN community,

We are trying to build a predictive model from the HANA PAL guide provided by SAP. Unfortunately we keep running into an error which is quite surprising since the code is copy pasted from the guide. Only the schema name is changed. Could one of the gurus please help us out? The algorithm is Random Forest.

The full code is also pasted at the bottom.

Thanks a lot!!!

Hi Thomas JungRich Heilman , Experts,

I have a query on XSA..

We recently upgraded our system to SP11.. With the launch of XSA in this SP, I decided to install the XSA runtime.. It was a single host installation with "worker" role assigned

After installation, I can see the components - xsuaaserver(active),xsexecagent(active),xscontroller(inactive) in System information (admin cockpit). When I restarted the instance I get the error "FAIL: process hdbxscontroller HDB XS Controller not running"

Will it be because of assigning role to host ?? ..

Can you please advice what can be done for fixing this..
