403 Error with destination to NWG service

I've configured a destination in a HCP trial account and I'm getting a 403 Forbidden error.  I'm able to access the service using Postman.

 

The configuration of the destination is shown below.  I followed the instructions in How to configure an external GW system with SAP Web IDE.

The relevant portion of my index.html file is:

 

<script>
       var oDataModel = new sap.ui.model.odata.ODataModel("/gbihana/sap/opu/odata/sap/ZOSCI_GBI_HANA_ODATA_1_SRV");
 
 
       var oSalesOrdersList = new sap.m.List({headerText:"All Customers"});
       oSalesOrdersList.setModel(oDataModel);
       oSalesOrdersList.bindItems({
          path: "/Customers",
          template : new sap.m.StandardListItem({
            title: "{CUSTOMER_NAME}"
          })
       });
       oSalesOrdersList.placeAt("content");
    </script>

and my new-app.json file:

 

 "routes": [
      {
      "path": "/gbihana",
      "target": {
        "type": "destination",
        "name": "HANAGBI"
      },
      "description": "Fiori Trial Demo Backend System"
    },

The error looks like this in Chromes developer tools:

I have successfully configured Open Weather service that Rui described in Lightweight HTML5 apps and Git on SAP HANA Cloud Platform but HCP is pretty new to me and I'm sure I'm missing one small detail but I'm out of ideas.  I've seen the error mentioned in the comments of a couple of blogs but there is never a resolution mentioned.

 

Any help would be appreciated,

Re: Does HANA support function in index?

Hmm... are you sure you found the largest possible font size for questions?

 

Quickly to your questions:

 

SAP HANA doesn't support function based indexes (FBI). Instead you can create generated columns (GENERATED ALWAYS AS - check the SQL reference for the exact syntax). These generated columns are semantically the same as FBIs

 

And indexes are always local to a partition.

 

All in all the most important thing about indexes in SAP HANA is that you really should not make the mistake and apply your Oracle-Knowledge of indexes to SAP HANA.

Although indexes are not completely irrelevant in SAP HANA they are way less important and required than e.g. in Oracle.

 

I've described indexes in SAP HANA in Richard's and my book (Book Announcement: SAP HANA Administration) in some more detail.

Re: Modification of subject table in trigger not allowed--

Instead of explicitly writing an update statement, you would simply assign the new values via the transition variables NEW.

 

Check the documentation, there's an example in there, if I remember correctly.

 

Besides that, my recommendation around triggers would be: don't use them.

If you want to ensure clean data entry to your tables - there are other and better methods to achieve this.

With triggers in place, you've build yourself a maintenance nightmare that not even you as the creator have a good grasp on, let alone the poor next guy who has to support the application in years to come.

Also, the required logic typically is not limited to just a single table (e.g. checking cross references, totals, etc.) and so you end up with a high level of barely visible dependencies.

Last but not least, triggers slow down your transaction processing and nobody wants that, right?

Hi All,

 

I am trying to create calculation views via scripts but i am getting some SQL errors. I have all the rights and the Scripts seems to be fine syntactically.

 

Can anyone suggest what could be the reason for the same. I am attaching the document having the error message screenshot and the script.

 

Please let me know if anyone has some solution.

Atul,

 

the attached log unfortunately doesn't contain the activation log error messages.

From one of the screenshots it's visible that at least one of the errors is that the view does not have any measures defined (on the semantic) level.

You can fix this by either defining a measure or declaring the view as a dimension view (without measures).

 

There also seems to be a second error, which I could not fully see. In case you need assistance with that too, please post the full activation log.

 

As a side remark: variable names like TABLE_1 or var_A are not a good choice ...

Hi Jimmy,

 

I've tried executing the statement

 

grant execute on system.afl_wrapper_generator to YOURUSER

where YOURUSER is HANA in my case.


But I am getting an error that grantor and grantee are the same.


Could not execute 'grant execute on system.afl_wrapper_generator to HANA' in 2 ms 723 µs .

SAP DBTech JDBC: [7]: feature not supported: grantor and grantee are identical

 

Then I created another user called ZIPSHOP and when I executed the command

 

grant execute on system.afl_wrapper_generator to ZIPSHOP

 

I am getting the error message:

 

 

Could not execute 'grant execute on system.afl_wrapper_generator to ZIPSHOP' in 12 ms 651 µs .

Can you please help.

 

Thank you.

Concat Distinct rows into a single string

Hi,

 

In my table I have rows like this

 

Table Name : Test

 

Name

-----------------------

sam

khan

sun

sam

 

My query

 

Select string_agg(Name,',') from Test

 

Output

 

sam,khan,sun,sam

 

But it is giving Duplicate values like sam comes twice.

 

Please help me to Eliminate duplicates while using string_agg function

You might be successful if you tell SAP HANA that you want the duplicates to be eliminated.

 

select string_agg_name,',') from

( select distinct name from test

)

 

You might be careful though when your inner select contains an aggregation already. Then the SAP HANA optimizer can find the DISTINCT to be disposable...

But that's problem to deal with when you face it

I'm trying to bulk post to an OData service and for some reason, the posting is failling. I know that in the http return, I already have a description regarding the error message, but is possible to check somewhere (maybe increasing a trace level, for example) a comple error message, or at least more details about the error?

Re: HANA Instr function to check for numbers?

Hi Echo,

 

I think that with a slight modification in Lars code,  you can acieve it

After replacing all the numbers with empty string, if the modified string is still same as the original string then the original string doesn't contain any numbers.

 

instead of  ::

 

if length(:tmp_string)>0 then

    isNumeric := 0;

else  

    isNumeric := 1;

end if;

 

you can replace it with

 

 

if length(:tmp_string)= length(:checkString) then

    isNumeric := 0;

else  

    isNumeric := 1;

end if;

 

Thanks to Lars for the cool logic.

HANA SQL Sub Query - Unique Record

November 15, 2014, 9:34 am
$

I have a sub query question on VBAP & VBEP.I want to get a unique record for my sub query based on the below criteria.

Appreciate any help on sql subquery.

 

1) Sort the data by VBELN,POSNR ASC & Confirmed Qty ( VBEP-BMENG)  DESC.

2) Now read only the first record for each Sales Order / Item. The result should extract ONLY one record from VBEP table.

 

Sample Data -1

 

VBAP Data

Sales Order               Item

320910685                10600

 

VBEP Data

Sales Order   Item        Schedule Line   Delivery Date    Confirmed Qty

320910685     10600      1                     10/21/2014           0

320910685     10600      3                     10/21/2014           0

320910685     10600      6                     10/21/2014           0

320910685     10600      7                     11/03/2014           100

320910685     10600      8                     11/03/2014           20

320910685     10600      9                     11/03/2014           30

 

RESULT:

Sales Order   Item        Schedule Line   Delivery Date    Confirmed Qty

320910685     10600      7                        11/03/2014            100

 

 

VBAP Data

Sales Order               Item

320910685                11800

 

VBEP Data

Sales Order   Item        Schedule Line   Delivery Date    Confirmed Qty

320910685      11800      2                        12/30/2015           1

320910685      11800      3                        12/30/2015           1

 

RESULT:

Sales Order   Item        Schedule Line   Delivery Date    Confirmed Qty

320910685     10600      2                         12/30/2015           1                              

                           [ OR ]

Not sure if your requirements are actually fulfilled by the following, but it should at least generate your samples:

 

SELECT ap."Sales Order", ap."Item", ep."Schedule Line", ep."Delivery Date", ep."Confirmed Qty"

FROM "VBAP" ap

     INNER JOIN

          (SELECT TOP 1 "Sales Order", "Item", "Schedule Line", "Delivery Date", "Confirmed Qty"

           FROM "VBEP"

           ORDER BY "Confirmed Qty" DESC) ep

     ON ap."Sales Order" = ep."Sales Order";



Looking at the sample result sets it looks as if it would be possible to select the data only based on "VBEP", but I assumed that there are some more selection criteria that you want to apply based on "VBAP".

Also, and don't take this the wrong way, but it is really a SQL beginner's question. So if you are going to develop more SQL it might be a good choice to top up your game and learn more about SQL programming.

Hi Thomas,

 

Recenty we´ve updated to SAP HANA and now I´m looking for what tecnology use to make a app to sell differents products with this app, I don´t know if this is possible or I must looking for other technology to do this...

perhaps Dot Net (ASP) + webservices or SAP Gateway (OData).... I don´t want to make a native application por Ipad, Iphone or Android....

 

I´ve decided to use SAPUI5 + SAP Gateway or WebServices in SAP, I´ve found SAP WEB IDE (before known as SAP River) this is a wysiwyg editor (great !!! at last !!!). I´m going to install the local demo to check the SAP Web IDE. But I´ve got a very big doubt. is it possible to use like this link ????

 

End to End Development Example with SAP NetWeaver 7.4 & SAP HANA

 

Or Must I use SAP HANA Cloud ???? If I need SAP HANA Cloud I won´t be interested.....

 

Could I use XS Engine from SAP Hana to house the app ????

 

Maybe I must write the application in SAPUI5 and I must forget the Sap Web IDE ????

 

Any help about this topic ?????

 

Thanks in advances and sorry for me english ....
