Change data type of RowID attribute "ID" possible?

November 16, 2015, 2:38 am
$
0
0

Dear all,

 

we redefined an easy query in our BW 7.31 system. The SEGW-process will integrate the attribute "ID" as key into the entities attributes. The data type is Edm.String without a definite length.

 

That is normally no problem. Now we want to be able to take advantage of the offline features of our SMP. However SMP has the restriction, that the key field has a maximum of 512 bytes. Therefore an unrestricted Edm.String leads to the following error in the SMP:

  • Caused by: com.sap.odata.offline.util.MODataException: [-100061] Property "ID" cannot be supported because it has a max length value that is too large for a key or referential constraint property

 

Is there a way to change the data type attributes of the generated "ID" attribute during service generation?

 

Thanks in advance!

 

Best regards, Daniel

Batch Operation error only with GET operation

Hi,

 

I'm trying to execute a batch operation and when I use GET operation, I get error "The Data Services Request could not be understood due to malformed syntax". It does not happen with any other operation (tested with PUT and POST).

 

I already tried several solutions discussed in the SCN, but I'm still getting this error.

 

My HTTP request:

 

get1.JPG

My response:

get2.JPG

 

Doing more deeply investigation (debugging) I found something interesting:

 

In method: PROCESS_BATCH (/IWCOR/CL_DS_PROC_DISPATCHER)

get3.JPG

 

And processing the BATCH, I found something that intrigues me:

get4.JPG

When it's processing the requests in the bacth, if operation is something different of POST/PUT/PATCH/MERGE/DELETE, in my case GET, the flow goes to exception and ends with the error above.

 

Does anybody already saw that? Any comments?

 

Thank you!

Flavio

error Resource not found for the segment 'SRMShoppingCartCollection'

Hello Everyone,

 

I am getting this error "Resource not found for the segment 'SRMShoppingCartCollection'" while opening an awaiting approval / saved shopping cart in UI5 Addon for SRM. The issue occurs randomly.

 

But, I could see all the required data loaded except for the error popup.

 

Steps that I already followed which didnt workout are:

  • Refresh Catalogs, Refresh Metadata for the SRMShoppingCart service.
  • Clear Cache.
  • Check for existing OSS notes (didnt find any)

 

I am confused why this service is unstable, that it runs fine some times and not some other time. I checked it for the same user, same shopping cart within a span of a minute and could observe the distinctive behaviour. When I put any external breakpoint, the issue doesn't seem to happen at all(didnt see it till now for some tens of runs). But when I remove the breakpoint the issue pops few times.

 

Also, should it not happen with shopping carts of all statuses.? It happens only for saved/awaiting approval shopping carts. and It happens when I try to open it from "My Carts" (Order tracking) as a requester.

 

Any quick help is appreciated, as I'm struck with this strange behaviour of the system.

 

Thanks & Regards,

Karthik

We need URI to test Odata service for Document number search help

Hi all,

 

We are trying to create an Odata service for Document Number search help.The search help should show (Controlling Area, Document No,Posting  date,Document date).The user should pass the Controlling area as a mandatory field to get the search help.

There is no elementary serach help at data element level. So we followed two approaches :

 

1) Create a CDS view . Call the Get Entity Set method to AMDP which queries from CDS view.

2) Create a Custom Search Help.Import this Search Help in SEGW .

 

*Now we can have multiple controlling areas as input.

 

We need to find URI so that we can test our service. For example we tried below :

 

/sap/opu/odata/SAP/ZCASE_TEST_SRV/Ztest1Set (works fine).

 

When the user gives Controlling Area :

/sap/opu/odata/SAP/ZCASE_TEST_SRV/Ztest1Set(KOKRS='US00')  (No Result , BAd request).

 

Can we give other parameters as blank like below :

/sap/opu/odata/SAP/ZCASE_TEST_SRV/Ztest1Set(KOKRS='US00',BELNR='')  (This also gives no result).


Can we write URI where we can give filter like :

/sap/opu/odata/SAP/ZCASE_TEST_SRV/Ztest1Set?(SIGN='I', OPTION='EQ', LOW='US00', HIGH='') ( Status 200, but no result )

 

Please suggest URIs so that  we can test the Odata service.

How to connect to my app logic in a central hub scenario

Currently, we have already deployed an ABAP OO application that is exposing custom services directly from the ABAP stack. We are planning to migrate the service layer to Gateway and are now looking at what we need to arrange to get this running in both an embedded as well as central hub deployment.

 

In an embedded gateway scenario, I'll just be able to launch my ABAP code from the service implementation. But how does this work in a central hub deployment? Would I have to wrap all my methods into RFCs in order to call them from there?

Supported OData Query Options

Hi all,

 

OData supports query options like $filter=cityfrom eq 'SINGAPORE' or $select=...

(A full list can be found [here|http://www.odata.org/media/16352/%5Bms-odata%5D.pdf])

 

1) Which options are supported by Gateway?

 

2) What is the "Gateway Solution" to filter the result of the GetList/Query command for a specific entity?

(e.g. return all flights with city of departure equal to 'Singapore')

 

Best Regards,

Florian

$filter option does not work after SAP_UI upgrade

We recently upgraded our SAP Gateway UI add-on to SAP_UI 740 SP13 (from SP10) as SAPUI5 libraries we were using were outdated. After the upgrade OData queries with $filter option do not work. OData services that use $filter option return empty result set. Example query that was working before the upgrade are as follows:

 

/sap/opu/odata/sap/ZCUSTOMER_LOOKUP_SRV/TShiptoSet?Kunnr eq '202768'

 

/sap/opu/odata/sap/ZGB_SRA016_PRICE_AVAIL_SRV_01/Customerhelp_shiptoSet?$filter=Mcod1 eq 'ABC*'  and  Parvw eq  'SH'

 

OData services that don't use $filter option are working properly. We have tried clearing the metadata cache on Gateway and backend for services in question and that did not help.

 

We are working on a fast track project and need this issue resolved quickly. Any assistance in this regard is highly appreciated.

Structure in Complex Type with Function Import and Cardinality 0..n

We are trying to use a complex type as the return type for a function import with cardinality 0..n. If the complex type is referenced to an ABAP structure, we dont get back any values. If i remove the ABAP structure reference, we get the correct output with multiple rows.

 

Is this a known bug or we are doing something wrong?

 

While debugging the framework code, came across a section which checks for "conversions" and if this is true, treats the complex type as a structure, ignoring the cardinality.

 

IF lo_complex_type->get_no_conversion( ) = abap_false.

 

          ASSIGN cr_data->* TO <ls_source_structure>.

          lo_struct_descr ?= lo_complex_type->create_data_descriptor( ).

          CREATE DATA lr_target_struct TYPE HANDLE lo_struct_descr.

          ASSIGN lr_target_struct->* TO <ls_target_structure>.

 

          /iwbep/cl_mgw_data_helper=>convert_complex_property_outb(

            EXPORTING

              io_complex_type     = lo_complex_type

              is_source_structure = <ls_source_structure>

            CHANGING

              cs_target_structure = <ls_target_structure>

          ).

 

          cr_data = lr_target_struct.

 

This code isnt executed if its a complex type without ABAP structure.

New version of HCI OData Provisioning service available on SAP HANA Cloud Platform trial landscape

Recently, things have been a bit quiet regarding HCI OData Provisioning (this is the service on HCP formerly known as 'Gateway as a Service'). Now, I have great news:


As of this week, a new version of HCI OData Provisioning is available on the SAP HANA Cloud Platform (HCP) trial landscape.

What is HCI OData Provisioning?

To make it short, HCI OData Provisioning gives you a new, additional deployment option of exposing SAP Gateway services to SAP HANA Cloud Platform. You might also call it your "Gateway Hub in the Cloud".

 

What's new?

In this version we have reworked a few things:

  • Destinations
    Destination handling has been changed to work with the destinations created in the HCP admin cockpit on subscription level (Services > HCI OData Provisioning > Configure HCI OData Provisioning).
    We have decided not to migrate the existing destinations, as we assume most destinations were used for test purposes only and did not want to import potentially obsolete destinations. So I would kindly ask you to recreate any destinations that you might have used before in the trial landscape.
  • Compatibility with SAP Fiori, Cloud Edition
    We have made some behind-the-scenes changes to enable all the cool SAP Fiori apps running in SAP Fiori Cloud Edition, which is now available in a controlled availability program for productive usage. If you are a part of said program, we can make HCI OData Provisioning available for productive use already today. For details on how to join the "beta" program, please have a look at this blog post: SAP Fiori Cloud Edition is now available for Productive Use!
  • Frequent updates
    We will now release updates to the HCI OData Provisioning service more frequently, potentially on a monthly basis.
  • User Interface
    We have updated the user interface to be consistent with the general theme used on HCP.

 

Does this mean that SAP Gateway is obsolete?

No. Basically SAP Gateway consists of two parts: One part is the Gateway Backend Enablement that allows you to build and create OData services, the other part is the Gateway Hub to expose the Gateway services (see the Gateway deployment options). You will still need to use the Gateway Backend Enablement in the future for the OData service exposure. However, as of SAP NetWeaver 7.40 the necessary SAP Gateway components come preinstalled, so in many cases you are ready to use HCI OData Provisioning with your SAP NetWeaver system straight out of the box.

 

What is planned for HCI OData Provisioning?

We are working with full speed on making HCI OData Provisioning available for productive use for everyone. The current plan is to make it generally available (GA) by the end of Q1/2016. (However, please bear in mind that there is always some uncertainty about unreleased software and therefore these plans might change. )

 

In addition to the use with SAP Fiori, cloud edition, there are some further cool use-cases planned on the SAP HANA Cloud Platform where HCI OData Provisioning will simplify your IT landscape setup:

  • API enablement: If you want to enable your Gateway services as APIs, HCI OData Provisioning can be used in combination with SAP API Managemt on HCP.
  • Mobile enablement: You might want to build some native mobile apps for iOS/Android/Windows Phone that require offline capabilities, or other mobile qualities. In this case you can use HCI OData Provisioning in combination with HCP mobile services.
  • Custom UI development: Of course you can also use the exposed Gateway services on HCP to build your own Fiori-like UIs using SAPUI5 technology with SAP Web IDE.

 

Feedback

Of course, I am happy to hear your feedback on this new release so that we can further improve the service, before it becomes widely available for productive use. So please write a comment below, send me an e-mail or if you encounter a bug, please open a support incident in component OPU-GW-OD-FW.

 

Enjoy!

Hello,

 

I am trying to implement mass creation of so order in gateway.

can you anyone provide me some snippets code on this?

 

I have defined in model

 

  lo_action = model->create_action( 'CONFIRM' ).

   lo_action->set_return_entity_set( 'SOHdr' ).

   lo_action->set_http_method( 'POST' ).

   lo_action->set_return_multiplicity( '1').   " what should we put here ??

   lo_parameter = lo_action->create_input_parameter( iv_parameter_name = 'WiId'

                                                     iv_abap_fieldname = 'WI_ID' ).

   lo_parameter->/IWBEP/IF_MGW_ODATA_PROPERTY~set_type_edm_string( ).  "What should we put here ?

 

can we define the type of parameter as a range of a table?

 

Thank you.

How to annotate an OData Attribute with sap:display-format="Date"

Hello experts,

 

for a Fiori SmartFilterBar I need an Edm.DateTime attribute to be recognized as a Date field.

Intention: From the annotation the Filterbar recognizes, that a Datepicker needs to be displayed.

 

I got the idea with the Annotation from here:

Re: Rules for OData datetime properties

 

 

The Annotation (display-format) is of course mentioned here:

SAP Annotations for OData Version 2.0

 

 

I do not see any option to set this Annotation for my attribute in transaction segw.

The explanations on the second link confused me quite a bit.

 

Any hints appreciated.

Error /IWCOR/CX_DS_BAD_REQUEST while using Deep Insert

November 24, 2015, 8:21 am

Hello fellow SAP GW experts. I have found myself stuck with an issue trying to test my code for a Deep Insert Service.

 

The structure of the entities is something of the sort:

 

-LoanRequest

Contains: Loan Data, this is a header data

     -Customers:

       Contain: Customer Data, this is a table, the loan request may have associated 1 or n customers to it

      -CustomerLoanProperties:

        Contains: The corresponding customer's conditions for the loan, like the amounts, card numbers and such.

 

The relationship is as follows:

 

Loan can have 1 or n Customers, and Customers can only have 1 loan properties each.

 

In order to generate the payload we redefined the expand_entity method given that a simple $expand wouldn't let us generate a real payload for this case given the relation/navigation properties as far as I tried, I might be wrong tho.

 

The issue on question is that, once we get a succesfull answer from the expand entity method we redefined, we use it as a payload, however once we change it to a POST method, the error we're gettng is:

 

/IWCOR/CX_DS_BAD_REQUEST: The Data Services Request could not be understood due to malformed syntax


Logs give the same text so there's no real way to pinpoint where in the XML the syntax is wrong.



I'll also add the payload request for more clarity on this issue.


In any case if you guys could advice me in any tool that could help me analyze this better, since the logs are too generic to understand the issue. Or what would be a better way to achieve the creation of payloads for DEEP INSERT operations.


Thank you guys in advance.


Cheers.
