In this blog, I will demonstrate how to create a new Opportunity by consuming C4C standard OData service via ABAP code.
The related OData service for Opportunity with detailed explanation on its entity types could be found from SAP help:
I will use a HTTP POST request to finish the creation. A example about how to organize post body could be found from C4C OData development guideline, where ServiceRequest is used for demonstration. I just make minor changes to make it also works on Opportunity.
First I test it in postman to ensure the successful creation:
I paste my http request body text here for your reference:
--batch_1Content-Type: multipart/mixed; boundary=changeset_1--changeset_1Content-Type: application/httpContent-Transfer-Encoding: binaryPOST OpportunityCollection HTTP/1.1Content-Length: 5000Accept: application/jsonContent-Type: application/json{ "AccountID": "8000018122", "OwnerID": "8000018122", "Name": {"content": "Testing ticket creation via OData Jerry1"}}--changeset_1----batch_1--And a new opportunity could successfully be created in postman:
Now all I need to do is just to translate the activities I have done in postman into ABAP code.
I wrote an ABAP report to create Opportunity by consuming OData service:
zcl_odata_tool=>get_csrf_token_and_cookie( IMPORTING et_cookies = DATA(lt_cookie) ev_token = DATA(lv_token) ).zcl_odata_tool=>create_opp( iv_token = lv_token it_cookies = lt_cookie ).Execute the report, new opportunity could be created and found in system:
