SAP GW Service Builder - How to recover unintentionally deleted project

August 24, 2015, 7:32 am
$

Hello everyone

 

I accidentally mangaged to delete the SRA016_PRICE_AVAIL (SAP Standard Service for Fiori App) project in SAP Gateway Service Builder. Don't ask me how this happend exactly. I most probable just misinterpreted something during my 1st redefinition trials with it.

 

Is there an easy way to recover the project data for it?

 

...DPC_EXT and ...MPC_EXT classes are still there.

 

Unfortunately I don't have a EDMX file of it to reload using the import function... if that would be the solution.

And unfortunately I even don't have another system to create the $metadata from it as it happend on our sandbox system.

 

The only way I can think about it right now is to restore the system from a recent backup we have. But this would have some other impacts I'd like to avoid if somehow possible.

 

Thanks in advance for any help on it!

 

Regards

Renaud

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".

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?

SAP Gateway and Simple Field Extensibility - does it work with append views?

September 18, 2015, 3:42 am
$

I read about the Gateway's Simple Field Extensibility and set up a small example with:

  • a database view on an existing table
  • a new OData Service based on the view with a single Entity Type and its Collection Type - i.e. the entity type is linked to the view structure
  • I implemented the get_entityset method in the data provider extension class with a simple SELECT * statement
  • when I execute a query on the Collection I get back the view data, as expected

 

So far, so good. Then I created an append structure for the underlying transparent table with a single field and a view append for the view I use as data source. When I then execute a query on the Collection I get back exactly the same view data as before, i.e. without the appended field.

 

The SAP help documentation (like above) tells us that:

 

At runtime SAP NetWeaver Gateway classes (model provider class and data provider class) consider the fields in the extension includes in ABAP Dictionary structures. That means that entity sets that are technically based on ABAP Dictionary structures for which SAP provides the option to extend them via append structures will automatically show new properties if the underlying ABAP Dictionary structure has been enhanced by the customer. This process is called Simple Field Extensibility (SFE). Properties that have been created by using SFE contain the annotation sap:is-extension-field="true".

 

I supposed that this works with append views as well, and am a bit astonished that it doesn't seem to work with my example.

 

Does anyone have some experience with using the Simple Field Extensibility feature?

Dear specialists,

 

as my previous post is located in the wrong area (How to access request object in Model Provider Class),

I repost my question here:

 

I want to define the data model of my OData service dynamically depending on an URI paramter of my HTTP request. But so far I did not find any possibility to access the request object in the model provider class.

 

Does anybody has a hint for me?

 

Many thanks in advance.

Netweaver Gateway : Multiple Output Tables : Odata

Hi,

 

I have created a RFC in ECC system. The RFC reads certain values and returns data in three output tables. The corresponding data model has been created in netweaver gateway.

 

When the portal application is trying to consume this service, it has to specify a particular table in the odata. Thus, to get the data of the three tables, the portal application is hitting the SAP database 3 times.

 

Could anyone please advise, how can we get the data for all the 3 tables in one go.

Jiten
