Getting data from SAP backend into Gateway Hub
Dear all,
I am new to Netweaver Gateway. In my landscape the IWBEP component has been installed in the Gateway Hub system. In my custom OData service i want to get the data from my backend SAP ERP system using a BAPI.
I have created my custom OData service with the relevant components and have implemented the service using the BAPI method. While implementing the service i referred to the BAPI method from the SAP ERP backend system using the RFC destination (ABAP connection i.e. connection type 3) to the SAP ERP system created in my Gateway hub.
Now when i test the service, the service document and metadata XML are generated correctly. However when i test the entity set, i find that the data is NOT being extracted from the SAP ERP backend system.
What configuration/settings need to be maintained in the custom OData service so that the service refers to the correct SAP backend system? How does the gateway service determine from which system it should extract the data?
regards
Nitesh

Eclipse: unable to create a Gateway Connection
Installed SW (Frontend)
- Eclipse Juno
- Newest SAP Development Tools from https://tools.hana.ondemand.com/juno (ADT 2.7.5 etc)
Backend
- AS ABAP 7.40
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?

How to create WebService which has EntitySets inside EntitySet
Hi, I have an application which creates new employees in a company. For that I have a form with multiple form containers (sapui5). Each form container corresponds to a certain abap table in sap system. I would like to know how can I import and map a WebService In NW GW which corresponds to the following entity relationships:
<EmployeeCollection> <Employee> <MainDetails> <Empfirstname></Empfirstname> <Emplastname></Emplastname> ........ </MainDetails> <ContactDetails> <Email></Email> <Workphone></Workphone> ........ </ContactDetails> <FamilyMemberCollection> <FamilyMember> <Firstname></Firstname> <Lastname></Lastname> ........ </FamilyMember> ........ </FamilyMemberCollection> </Employee> .....</EmployeeCollection>
I have Employee collection which can have 0...* Employees. Employee has Entities like MainDetails and ContactDetails AND also Collections like FamilyMembers which can have 0...* FamilyMember entities.
In SAP I dont have a table for Employees, all employee related details are held in different abap tables like MainDetails, ContactDetails or FamilyMembers. The tables are related by Formid field. Now FamilyMember table can have multiple lines with the same Formid (family members of an employee).
I can map a CREATE operation in SEGW for this, IF everything is singular.
What do i need to do differently in GW or Function module to be able to handle insertion of multiple family members into the FamilyMember abap table?
Also, how can I map GetEntity and GetEntitySet oprations so it would output me the kind of structure as i illustrated in the above code?

Creating data of Association Sets.
Hi,
I'm looking for a way to use Create method for a AssociationSet. Example: To create a PO with line items, I will need to pass line item data and header data and then pass this to BAPI_PO_CREATE
Now I need to implement a Gateway service that can create new PO by passing XML payload.
I searched for this but mostly all posts are related to retrieving data of a association by implementing method in the DPC_EXT class but I could not find one to create new one.
Thanks for your help in advance.

OData Excel Upload by 'Add File' button in GW_CLIENT gives junk characters
Dear Folks,
Greetings !!
I request your guidance in resolving the "well known" excel upload problem using GUI_UPLOAD in ABAP. I understand that there are large number of threads dealing with the excel upload issue, however I have a psecific question to ask.
I have created an OData service to upload an excel file (Entity type = Media). For testing the same, I am uploading a test MS excel file in the GW_CLIENT using the 'Add File' button. The file gets uploaded but appears as junk characters in the request body. Please refere to the image attached herewith.
I debugged the 'Add File' button and understand that the SAP standard code uses method GUI_UPLOAD of the GUI frontend services class, with Filetype = 'BIN' (hardcoded) to upload the file. The BINARY data received after the GUI_UPLOAD is also correct since I tested this by downloading the same BINARY contents and this creates the same excel file after download. This means that the excel is read correctly by GUI_UPLOAD.
On more debugging and searching in the SCN forums, I stumbled upon an answer by Thomas Jung in a post (Re: Upload a file excel with web dynpro) stating that the characters uploaded are not JUNK but they are the Native Binary Excel Format which is a propriatery Microsoft format. Therefore when I try to convert the XSTRING of this binary to STRING, the contents are not the excel text contents, instead it is these junk characters.
So, my question is - Is there any way (FM, BAPI, custom code) in ABAP to convert the native binary excel format into readable text?
Any pointers are highly appreciated.
Thank you.
Regards,
Sud

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
