The navigation information 'ErrorCaseSet_ERRORDETAILSET' is not valid

May 12, 2015, 4:54 am

Hello,

 

I created a project in SEGW and used for my header and detail structure for each a different ABAP CDS view. I built an association from the header to the detail which has a 1..1 relationship.

 

When I test this all works ok, e.g. I get data for my both entity sets but if I navigate to my detail it doesn't work:

 

/sap/opu/odata/SAP/Z_IDOC_TOOL_SRV_03/ErrorCaseSet('0000000000000001')/ErrorDetailSet

 

Get this exception:

 

CX_SADL_CONTRACT_VIOLATION


The navigation information 'ErrorCaseSet_ERRORDETAILSET' is not valid


So I'm on WAS 7.40 SP9 and the Gateway is patched to SP12. I tried to look in OSS for this error but found nothing. Is there a good way to troubleshoot this association stuff?.


Here my config:


And the error:

 

The application log etc. doesn't really say more. Somehow it doesn't like this ErrorCaseSet_ERRORDETAILSET. This comes from here:

 

Any idea anybody?

 

Thanks

SAPUI5 program consuming gateway service

Hi,

 

I have Netweaver Gateway Server set-up. I have Eclipse Kepler installed on my machine with SAPUI5 plugin added to it.

 

Now I want to write a small SAPUI5 program which can consume the service created in Netweaver Gateway server.

 

Can someone please let me know any websites/SDN sites which can help me get trained on this and create my own demo application.

 

I am a java developer and know JQuery & javascript. But I have no knowledge of ABAP programming. So please let me know if I need to have ABAP programming knowledge also if I have a to create a service in Netweaver Gateway sever.

 

My objectives are :

 

1) Create a service in Netweaver Gateway Server

2) Write SAPUI5 program in Eclipse to consume the service created in Netweaver Gateway Server. (One doubt I have is,..once I create a SAPUI5 program, will I have to deploy it in Netweaver Gateway server? ..If not then where will this SAPUI5 program will reside?)

3) Run the SAPUI5 program.

 

Thanks.

Web Service/Required roles

Hi,

 

I have created a web service in Gateway with transaction SEGW. The web service works perfectly fine and it is being called with a RFC. I've tested the web service using REST as well.

 

The mobile app that is calling this web service does so successfully in our Production system, but once we try to perform the same action in our QA system, I am denied any access to log into the mobile app. I have mimicked the users' roles in our Production system into their roles in the QA system and yet it still does not let me log in.

 

In order to log into the mobile app, the user uses their SAP credentials.

 

Does anyone know if there are user-specific roles in QA system that is required, but not required in the Production system?

 

Thanks.

Application log: Metering information missing for: consumer_type

Hello experts,

 

.. when checking the application log on the gateway system (dedicated system) I see all log entries beeing marked as warning.

 

Every OData service calls causes this warning:

 

/IWFND/CL_METERING_API========CP

CHECK_CONTEXT

 

Metering information missing for: consumer_type (Message Text)

/IWFND/CM_COS127 (Error Code)

 

I searched a lot, but didn't find any useful information on this (except for SAP Fiori [defining scenarios], which is not in place) and tried some HTTP header entries as well as some config actions, but did not succeed.

 

Which configuration step(s) we are missing?

 

Thanks,

Robert

What do 'GetEntitySet (Query)' & 'GetEntity (Read)' do.

Once we create a project in Netweaver Gateway and follow few other steps to create a OData service, we come across two methods which I think are very important for service implementation perspective.

 

Can some one please tell me what exactly does these two methods do : 'GetEntitySet (Query)' & 'GetEntity (Read)'

 

I am a Java developer / SAP Portal consultant so thinking that these are ABAP specific. But if some one can explain briefly I think I will be able to understand though I have min ABAP knowledge.

How the performance oData comparing RFC's

Hello Experts,

 

I am new to SAP Mobile technologies.

 

My client already using web based .net application and there are many RFC Function Modules already exist and the same RFC Function Module called from .net application.

 

Ex: To fetch open Sales order and changing the status from .net. Actually inside R/3 RFC Function Module called the standard BAPI and returning result to .net web application.

 

Note : Now our client is upgraded into ECC 6.0 from R/3 4.7.

 

I have come across from scn forum the oData can be used in any programming language(ASP/.Net/PHP/Phython/Java and etc.)

 

Can we migrate all RFC's to oData service using netweaver gateway programming. Below are my basic questions.

 

1. What is the advantage using oData comparing RFC's? is there any merits and demerits using the new oData technology? It is advise to use oData?

2. Will it support network load since many RFC's are returning around 50K records to .net.

3. My client planing to implement mobility and my basic question is what is the use of Syclo, Agentry and Fiori? is all the three can be used oData framework? My client proposed to use Syclo Agentry so the oData framework will it support? I heard the oData is the platform independent and can be connect any source.

 

Please advise me. I am waiting for your earliest response and best practice as well.

A Vadamalai.

Backend

Hello Collegues,

 

I've created a NW Gateway Service on the backend (Service is working correctly) and now I want to create a UI5 Application on the Eclipse site.

Before creating the project I have to create a Gateway connection first. But I'm getting a "Network Connection Error".

 

error.PNG

Connection data (host, port) is correct, also tried with IP instead of hostname already.

I'm getting the same error if I'm using the (new) ES Workspace data (sapes1.sapdevcenter.com, Port 80?).

 

Tried also on another PC, same error.

 

Any ideas?

I want to create a service using service builder on AS ABAP incl. BW 7.4 SP8 on SAP ASE 15.7

Later add it as destination or Gateway as Service on HANA Cloud Trial.

And consume the same in HANA Cloud Trial applications.

Is this possible ? I see that these developer editions are having some dummy link ?

So unable to configure the same on HANA Cloud Trial.

 

Or is there any instance of NetWeaver available that allow us to create OData that can be consumed within HANA Cloud Trial account ?
