Send Image CL_HTTP_CLIENT

2023-02-27T18:08:38+01:00

Hello Experts,

I need to send an image via the post method of cl_http_client. The target system is expecting the image in binary format. I have tried using 'SCMS_XSTRING_TO_BINARY' but this gives the result in hexadecimal format. I then tried passing xstring and base 64 encoded file but the target system is unable to convert it. Is there anyway to achieve this?

This is Service Now API, I am trying to add an attachment to an Incident. This is the link for API documentation.

https://developer.servicenow.com/dev.do#!/reference/api/rome/rest/c_AttachmentAPI#attachment-POST-file

I am using POST/now/attachment/file

I need to add the image in request body. here is the documentation screenshot for your reference.

Below is the sample code I am using

Support for Data Compression in OData V2 response

2023-05-17T10:09:40+02:00

As per the SAP Documentation, How to Enable Compression. I followed the instructions and tried to achieve data compression. Unfortunately, it didn't work as mentioned in the document. I passed the request Header Accept-Encoding and set to gzip and made a HTTP GET request call. On receiving the OData HTTP response there was no change in the content-length nor some information in the response header stating the data has been sent in a compressed format. Do I need to make any configuration changes for the SAP GATEWAY CLIENT or enablement of any sort of Network Compression in order to achieve this?

question abount http response size limit

2023-07-24T07:19:08+02:00

Dear SAP developers.

Developers in my project will develop ODATA API in S/4HANA.

I worry that large http response may kill ICM.

I know i can restrict http request size using ICM parameter: icm/HTTP/max_request_size_KB.

so, my worries about http request side is cleared.

then, is there other parameter which can restrict http "response" size?

Parameter for memory pipes "mpi/total_size_MB" may seems to do it.

Question is whether "mpi/total_size_MB" intended for restricting the size of a single http response or it is intended for restring the total size of all http response.

or, is there other paramter which can restrict http "response" size?

Best regards.

Activate a given web service

2023-08-31T06:19:11+02:00

Hi Experts,

I was told to activate Web Services. I did google but couldn't find 100% satisfying solution.

I have these 2 details:

Service Name: EmployeeMasterDataBundleReplicationRequest_In in component PA_SE_IN

Service URL (Called by middleware) : http://sd1ascs.clientname.loc:443/sap/bc/srt/scs/sap/employeemasterdatabundlerepli1?sap-client=550

I followed this link:

https://www.linkedin.com/pulse/how-activate-web-services-sap-find-wsdl-end-point-urls-rajesh-dadi

But i am hearing that "its NOT active complete with some connection error while accessing"

My action: I went to tcode: SOAMANAGER and then i chose "Simplified Web Service Configuration".

In the "Search Pattern", i happened to input *Emp*Bundl* and pressed 'GO'.

I happened to see Web service Name or Service Definition(i think) under Internal Name column.

I checked on the box Username/Password(basic) and saved .

I got msg under "Text" column like "activation successful" with config name : 98798777978

Please tell me if i did something wrong?

Thanks
