Yes can be done.

You can go to the transaction /IWBEP/REG_SERVICE and then you can maintain the service to whatever naming convention you wanna follow. I hope that will solve your problem. 

I am writing an app in .NET c# to call netweaver gateway services. GETS work fine. I get 403 Forbidden when I try a PUT. I know this is due to an issue passing the x-csrf-token in the POST, but I am using "Fetch" to get the x-csrf-token and passing it on the POST, so I don't know why it is not working. I have seen other posts by people having the exact same issue, but I have tried everything suggested in the replies without avail. What am I doing wrong ?

I have tried using "Postman" to manually fetch an x-csrf-token and use it in a POST (again using Postman) and this DOES work.

I have noticed that when I run my code:

1. I get a different value for the x-csrf-token every time I do the GET. Using Postman the same x-csrf-token is returned each time (until it expires and a new one is returned).

2. If I copy the x-csrf-token I fetch in code and paste it into Postman as the x-csrf-token for a POST then Postman FAILS (CSRF token validation failed).

3. If I copy the x-csrf-token manually fetched using Postman and paste it into my code as the token, my code still fails. This is really odd as that token continues to work if I use is for another POST using Postman - so it IS a valid x-csrf-token.

When I run my code, the "response" I receive back is:

Hello Gateway Pros,

We have a mobile application that field technicians logon to tablets and perform various transactions ( for eg  enter time, create/post  parts order ) .

Currently we have a setup (  Non SAP mobile platform UI  <=> non SAP middleware with DB  <=>  legacy application ERP  ) which we be rolling out SAP to replace Legacy ERP.   existing  Mobile platform and  non sap middleware are designed to work together  for eg to process order when tablet goes offline.

We have  SAP PO  with REST adapter and SAP Netweaver gateway  in landscape ,  now the questions is  deciding which one would best suit  the scenario.

I have read various blogs  on SCN which has given me a good idea about the PO capabilities vs  Netweaver  but  I have few more questions

1) Can SAP Netweaver  good tool to use if we have to communicate large set of data any limitations ?

for eg  if the mobile application requests for all Parts in inventory and there customer pricing

2) PO comes with great monitoring tools does SAP Netweaver   has those capabilities

3) can SAP Netweaver handle offline scenarios  any link that explains offline scenarios will be great help ?

4) what are  the advantages  or disadvantages of using  SAP Netweaver over SAP PO  ( specific to my scenario )

Thanks for your time.

Raj

It  doesn't work. One of the SInk file has error.

Hi Lakshman,

It sounds to me if you do 4 entity sets, you don't need 4 different OData URL.  It seems you need to set associations between entities and maybe NavigationProperty for EntityType as well. Then by calling one URL you can get all results back.

This is an example for standard OData for SRM Shopping Cart:

http://:/sap/opu/odata/GBSRM/CARTAPPROVAL;v=2/WorkflowTaskCollection('000000342035')/SCAHeader

It gets WorkflowTask and SCAHeader associated with WorkflowTask.

Other thing you can use $expand which is like inner join for SELECT statement.

Take a look into these:

Hi,

One more question I try insert many records from one request like

Request A(key is generate when insert the items from bapi) : [ 0 : { more than 1 field }

                                                                                           1: { more than 1 field }
                                                                                          ]

Can you tell if you know how can I read twice times the same data from sapui5 and what I need to do in method create please ?

Sorry if my english is wrong

Best Regards
Thanks for your time

Hi Aggarwal, have you been able to solve this issue?

We have a custom SAPUI5 application that runs on a standalone laptop that needs to download / get data from SAP. We are receiving the same SOP / CORS 401 error messages. I've tried to change the return header from SAP via the gateway service method /IWBEP/IF_MGW_CORE_SRV_RUNTIME~READ_ENTITYSET

but with no luck.

call method super->/iwbep/if_mgw_core_srv_runtime~read_entityset

    exporting
      iv_entity_name           = iv_entity_name
      iv_source_name           = iv_source_name
      is_paging                = is_paging
      it_order                 = it_order
      it_filter_select_options = it_filter_select_options
      is_request_details       = is_request_details
    changing
      ct_headers               = ct_headers
      cr_entityset             = cr_entityset
*     cr_deleted_entityset     = cr_deleted_entityset
      cs_response_context      = cs_response_context.
*    ct_inline_info           = ct_inline_info.



  data ls_header  type ihttpnvp.

  ls_header-name = 'Access-Control-Allow-Origin'.
  ls_header-value = '*'.
  append ls_header to ct_headers.

  clear ls_header.
  ls_header-name = 'Access-Control-Allow-Credentials' .
  ls_header-value = 'true' .
  append ls_header to ct_headers.

And also in method /iwbep/if_mgw_conv_srv_runtime~set_header.

data: ls type ihttpnvp.

  ls-name = 'Access-Control-Allow-Origin'.
  ls-value = '*'.

  call method super->/iwbep/if_mgw_conv_srv_runtime~set_header
    exporting
      is_header = ls.


  ls-name = 'Access-Control-Allow-Credentials' .
  ls-value = 'true' .

  call method super->/iwbep/if_mgw_conv_srv_runtime~set_header
    exporting
      is_header = ls.

Hi Jesse,

No we have not. I have a SAP OSS ticket opened too and SAP told that current version of the Gateway does not support CORS. We changed our architecture not to hit the gateway service directly but go through PHP server.

But in our scenario we are trying to access ODATA from the Non SAP HTML 5 application. In your case it seems to be SAPUI5 application. With SAPUI5 application we didn't have any issues as it was running on the SAP Gateway server itself.

Are you running the SAPUI5 on the local ABAP server?

Thanks,

Rohit

Actually, this app. is a standalone app. on a laptop so to have the ability to work in remote isolated locations offline but still to have the ability to occasionally connect online.

So all the SAPUI5 "resources" / libraries are on the laptop. We just need to connect to the backend to download certain master data and to upload data once back in the office.

Hi Atanu,

Thank you for the details provided.

Using draft approach , Fiori apps can achieve collaboration, locking and usability features.

For custom UI5 applications NOT using S/4 HANA:

Do we have create OData services consuming BOPF objects and inturn BOPF framework will handle the locking(draft approach) implicitly ? Please suggest if there are any example implementation in the existing SAP NW releases to understand the methodology.

Appreciate your help.

Regards

Santhosh Kumar

Does the user connecting to the Company network using VPN during the time SAPUI5 app connects to the backend server. If yes then you should not be getting this issue. If no then you will depending on if your gateway server is accessible from outside company network or not.

Hi Experts,

I have done some posts for understood the functionality batch. But I can't understand how can I insert many records from sapui5 for sap gateway netweaver

I have the following scenario:

The users create items and this items need to be sent for sap gateway netweaver to generate the request with an existent bapi.

My doubt is how can I send many records in same request and how can I read this inside sap gateway in method created ?  Can you please share a tutorial or explain me how can I do this ?

Thanks very much for your help.

Cristina Rodrigues

Hi,

Can I get an example as to how to call a batch request for POST in UI5 for the below:

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

Accept: application/xml

GET ztotal_EmpSet/?$filter=StartDate+eq+datetime'2016-08-24T00:00:00'+and+EndDate+eq+datetime'2016-08-28T23:00:00'+and+Unit+eq+'50006636'+and+DateField+eq+'BASIC'+and+Id+eq+'1'HTTP/1.1

--batch--

Any link would also be helpful.

Code:

var allfilters = [new sap.ui.model.Filter({
  path:'filter1',
  operator : sap.ui.model.FilterOperator.EQ,
  value1 : this.filter1value
  }),
  new sap.ui.model.Filter({
  path:'DateField',
  operator : sap.ui.model.FilterOperator.EQ,
  value1 : 'BASIC'
  }),
  new sap.ui.model.Filter({
  path:'StartDate',
  operator : sap.ui.model.FilterOperator.EQ,
  value1 : oDateFormat.format(this.startDate.toDate())
  }),
  new sap.ui.model.Filter({
  path:'EndDate',
  operator : sap.ui.model.FilterOperator.EQ,
  value1 : oDateFormat.format(this.endDate.toDate())
  })];

  var batchrequest = this.oModel.createBatchOperation('/ztotal_EmpSet','GET',{
  filters : allfilters
  });
  this.oModel.addBatchReadOperations([batchrequest]); 
  this.oModel.submitBatch(this._gotData.bind(this),function(err){
  console.log(err);
  });

I am not getting values in the it_filter_select_options in the backend while debugging.

Gopa

Hello Cristina,

What is the operation you are doing ? POST ?

Regards,

Ashwin

Hi Cristina,

Please check below link, that may help you.

Gateway Batch Calls from SAPUI5

And, in gateway you will get records one by one, In case you need, set a breakpoint in back end for batch operations, just set a break point in method CHANGESET_BEGIN or CHANGESET_END.

Regards,

Akhilesh

You need to create your batch payload as shown below.

Sample one ->

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

GET get_emp_dataSet?$filter=Userid+eq+'00001' HTTP/1.1

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

GET get_emp_dataSet?$filter=Userid+eq+'00002' HTTP/1.1

--batch--

Hello Ashwin ,

Yes, I want to do the operation post.

Best Regards,

Cristina

Hi Akhilesh,

I saw this tutorial but anyone explain what I need to in method created and if I need make any change in methods CHANGESET_BEGIN and CHANGESET_END.

My question is , what is necessary to do in methods created , CHANGESET_BEGIN and CHANGESET_END for put the items I need in a table , but read one by one from http request ? For me is a little confused.

Because from what I understand is that the gateway can read many records but I don't know if this records need to be separated.

Thanks very much
