Hi Chandra
When I do it within 60 seconds, I still got an error message
404 Not Found
Any suggestions?
Can I see anywhere if I am doing something wrong? (When I am debugging, I don't get any errors).

Re: Generate PDF file in backend, and "send" it to SAP Gateway
Hi Lars,
What Chandra is describing is nothing to do with Gateway 
In order to expose a binary representation (such as a PDF or photo) of a resource through OData you need to use the media streaming solution. The client can then use the appropriate handling for the Mime type.
The following code is the tail end of an example of a SAP Office document (which is a PDF) which has been read into table lt_hex - this is converted to binary which is placed in the stream. You need something similar to this in the GET_STREAM logic.
* not very useful code prior to this which fills lt_hex is omitted
data: ls_stream TYPE ty_s_media_resource.
data: lv_solix type solix.
data: lv_input type i.
describe table lt_hex lines lv_input.
read table lt_hex into lv_solix index lv_input.
lv_input = ( ( lv_input - 1 ) * 255 ).
lv_input = lv_input + xstrlen( lv_solix-line ).
call function 'SCMS_BINARY_TO_XSTRING'
exporting
input_length = lv_input
* FIRST_LINE = 0
* LAST_LINE = 0
importing
buffer = ls_stream-value
tables
binary_tab = lt_hex
exceptions
failed = 1
others = 2.
if sy-subrc <> 0.
* Implement suitable error handling here
endif.
ls_stream-mime_type = 'application/pdf'.
copy_data_to_ref( exporting is_data = ls_stream
changing cr_data = er_stream ).

Re: Generate PDF file in backend, and "send" it to SAP Gateway
Hi Lars,
Replies have "crossed in post", but as you can see, in my latest response the code is very similar. All you need to do is copy my example and drop all the cached response stuff.

Re: File Attachment using gateway
Hello John,
I want to upload a file like PDF or DOC from ui5 to backend, using oData.
I created a gateway service.
I know that I must redefine create_stream method, but I don't know how to do that.
Do you have an example, how to write this method in abap?
Thank you,
Mari

Re: Unable to retrieve data with inside-out approach
Facing few issues executing the BAPI_EPM_SO_GET_LIST , requested my abap team to help on this.
In the mean while started to work with another BAPI_FLIGHT_GETLIST which works well in our SAP system.
Build a SAPUI5 app with the AppBuilder consuming a NW Gateway service - series 1 of 2
The runtime objects are generated successfully, system is registered and made sure the services are activated.
but when executing the service in /IWFND/GW_CLIENT,with the activated service, only the $metadata query is successful, but not the others.
Facing 500 internal server Error with FlightSet entity
Screenshot of the error log :
Is this because of any missing in configuration / steps / patches on SP05 system ?
↧
Re: Unable to retrieve data with inside-out approach
I performed same steps and created demo service. I am not getting any error and got the result for query /sap/opu/odata/sap/ZSCN_FLIGHTDEMO_SRV/FlightSet
but our system is SP08 and hence seems to be issue with some missing patch in your SP05.
looking at error, it seems to be problem with date time parameter. you can try without those fields or try with code based implementation as explained in my blog Let’s code CRUDQ and Function Import operations in OData service!

Re: Unable to connect to OData service from Eclipse Juno + Kepler
Hi Carlos,
that works with my Eclipse Kepler - thanks a lot. I still got some syntax errors in the code, but that´s another story, I am gonna look into it in the next two days.

Re: Getting error "Invalid or no mapping to system data types found" after sending file
Hi,
it was the reason for me. As stated in Enabling Media Links - SAP NetWeaver Gateway Foundation (SAP_GWFND) - SAP Library - Media type is only supported for feed and entry. You should redefine the method DEFINE() of the model provider extension class generated by the SB to avail the media link functionality.
So it seems that create_entity and get_entity_list works, but in order to make get_entity work you need to redefine MPC_EXT. And after create_entity you need to call get_entity in the code to get successful response from gateway after upload.
Best regards,
Peter

Re: Unable to retrieve data with inside-out approach
Thanks Chandra , Will try the same .
I also assume that a couple of patches to be applied to the SP05 server to resolve any similar issues.

SEGW: Howto set subscribable with vocablary based annotations?
Hi,
according to http://help.sap.com/saphelp_gateway20sp08/helpdata/en/41/c49c527bf4487a842295263e01d9ad/content.htm one can set Subscribable on an entity set and then the appropriate coding is supposed to be generated. However this checkbox seems not to be available when using vocabulary based annotations. So how do I set subscribable with vocablary based annotations?
Thanks in advance,

Filter on date using variable
I have a variable for a date that is 60 days old called date60days. I want to filter out any frequently used items from the launchpad gateway service where the last used date is greater than 60 days. I am unsure how to utilize the variable in my filter. I have tried the following:
$filter=myLastUsed gt datetime'" + date60days + "'&$orderby=myLastUsed desc",
I was able to do this in the javascript itself by using a condition on the for loop when adding the links as follows:
if (ostaticlinks[i].myLastUsed > date60days ) {
however, I'd rather filter this upfront rather than retrieving so much data from the backend. Do I just not have the syntax correct for the $filter?

Re: Filter on date using variable
Hi Roger,
is variable date60days in this expected format 2014-05-14T15:08:40 ?

Re: How to get HTTP headers from Data Provider Class?
Hello Atanu,
Thanks for the info. I was also not aware of that. Thanks again.

Re: How to get HTTP headers from Data Provider Class?
Hi Yauhen,
do you have your users stored in SAP, or in some external system?
If they are in SAP, after login to netweaver gateway, you can access sy-uname in the backend and make your filter logic of products there.

Peter

Re: How to get HTTP headers from Data Provider Class?
Hello Yauhen,
Please follow the code to get Headers like how Atanu has suggested and
implement Get_EntitySet and get all the products for that particular User.
Now the next question is how will you send table of users and get corresponding result ?
Since your approach is to send user name and password in the headers and use it to get list of products for that particular user,
even if you operate on BATCH for Query operation how will you send credentials of all those table of users in a single header ? You cannot set headers for all those users with their respective User Name and password correct ? Because Gateway does not support that.
Now its up to you how you would like to model your service and fire it

Ashwin

Re: Configuring SAP Provided oData services
Hi Krishna,
Atanu is right. You either need to deploy either IW_CNT on systems prior to 7.40 and IW_FNDGC on 7.40 systems in the Hub.
The services themselves are in maintenance mode and are not developed further. That's why they have been packed in 7.40 in a separate AddOn and are not shipped as part of the 7.40 standard.
This is because we (SAP) do not plan to ship content via SAP NetWeaver Gateway but rather are shipping services as part of complete solutions such as SAP Fiori.
Though the customer can use the services I would recommend to develop your own services instead (the BAPI's hat have been used are listed in the SAP Online Help).
Another option if no development is wished would be to have a look at the applications that we are shipping with SAP Fiori.
Best Regards,
Andre
