Senior SAP ABAP Developer

Senior SAP ABAP Developer (SD / Payments / Integration). Location: Canada. Travel: 7 days in month – to USA [candidate should have required Travel visa]. Job Type: Contract [6+ Months] – Corp 2 Corp. About the role:. We are integrating SAP ECC with Stripe so that customer-service users can take card payments against sales orders without any cardholder data entering SAP. The solution adds a button to the sales order (VA01/VA02) that launches a Fiori pop-up hosting Stripe's embedded checkout; Stripe returns a token that is written to the standard SD Payment Cards tab, and SAP's payment card engine then authorizes at order save and captures at settlement through custom clearing-house function modules that call Stripe via MuleSoft REST APIs. You will be the lead ABAP developer for the SAP side of this build: the sales order enhancement, the SD payment card plug-ins, the OData service on SAP Gateway, and the outbound REST integration. The design, reference code and a step-by-step implementation guide already exist; your job is to make it real in the customer's landscape, validate the release-specific parts in a sandbox, and carry it through testing and go-live with a functional SD consultant, a UI5 developer and a MuleSoft developer. What you will do:. Implement the sales order header enhancement in SAPMV45A (customer subscreen 8310 "Additional data B", PBO/PAI modules, MV45AFZZ user exits) that launches the Fiori pop-up, shows payment status and applies the Stripe token to the payment card plan (FPLA/FPLTC). Build the SD payment card clearing-house plug-ins: card type check, authorization and settlement function modules (copies of CCARD_CHECK_*, CCARD_AUTH_SIMULATION, CCARD_SETTLEMENT_SIMULATION) that call Stripe through MuleSoft, including re-authorization, cancellation and partial capture. Work with the SD functional consultant on payment card customizing: card types and categories, checking groups, authorization horizon and validity, clearing house and merchant IDs, account determination, copy control to billing, settlement run (FCC1) and batch authorization (RSCCAUTH). Develop the outbound REST client (CL_HTTP_CLIENT / SM59 type G, OAuth 2.0 client credentials via OA2C_CONFIG, JSON with /UI2/CL_JSON), with idempotency keys, structured error handling, an API log table and no sensitive data in logs. Build and register the SAP Gateway OData service (SEGW, DPC_EXT) used by the Fiori pop-up and by MuleSoft webhooks, including CSRF handling, authorization objects and hub registration with trusted RFC. Design and create the custom tables, data elements, configuration views (SM30), message and exception classes, and authorization objects/roles for the solution. Run the sandbox spike that confirms release-specific behavior (payment card plan API, template function module interfaces, field lengths) and adjust the reference code accordingly. Support the UI5 developer with the Fiori app (semantic object, target mapping, Launchpad catalog/role, CSP for Stripe.js) and, if SAP GUI 8.x is in use, implement the embedded HTML-control variant with SAPEVENT callbacks. Own unit and integration testing on the SAP side against Stripe test mode (approvals, declines, re-authorization, partial capture, cancellation, webhook replay), and produce the technical documentation and transport plan. Apply secure-coding practices consistent with PCI DSS SAQ A scope: no PAN/CVV in SAP, no card data in traces, dumps or logs, least-privilege roles for technical users. What you bring:. Must have:. 10+ years of hands-on ABAP development on SAP ECC 6.0 (EHP 6–8, NetWeaver 7.40/7.50), including modern ABAP syntax (inline declarations, string templates, ABAP Objects, exception classes). Deep SD module knowledge from a developer's perspective: sales order processing (SAPMV45A user exits and BAdIs, screen enhancements, VBAK/VBAP/VBKD), deliveries, billing (RV60AFZ*), copy control, output determination and pricing. Solid understanding of SD payment concepts: payment card processing (payment card plan FPLA/FPLTC, card types, checking groups, authorization and settlement, clearing house function modules, FCC1), payment terms, down payments/billing plans, credit management basics and the FI postings that result from card settlement. Proven experience calling REST/JSON APIs from ABAP (CL_HTTP_CLIENT, SM59 HTTP destinations, STRUST/SSL, OAuth 2.0 or token-based auth, JSON serialization) and designing resilient outbound integrations (idempotency, retries, logging without sensitive data). SAP Gateway / OData development (SEGW, DPC/MPC extension classes, function imports, CSRF, hub/embedded deployment, service registration and authorizations). Experience with SAP GUI screen programming (Screen Painter, subscreens, PBO/PAI, GUI controls such as CL_GUI_HTML_VIEWER, CL_GUI_FRONTEND_SERVICES). Comfortable working from a design document and reference code, validating assumptions in a sandbox, and communicating trade-offs clearly to functional consultants and business stakeholders. Nice to have:. SAPUI5/Fiori development or close collaboration with UI5 developers: manifest and cross-app navigation, Launchpad configuration (target mappings, catalogs, roles), deployment via /UI5/UI5_REPOSITORY_LOAD. Prior work with a payment service provider (Stripe, Adyen, Cybersource, Paymetric, Delego or similar) or with SAP Digital Payments Add-on, and familiarity with PCI DSS concepts (tokenization, SAQ scope, MOTO). Exposure to MuleSoft or another API platform as the integration counterpart (RAML/OpenAPI contracts, webhook handling). S/4HANA experience and awareness of how ECC custom code migrates (custom code analysis, simplification items). Pay: $45.07-$86.61 per hour. Work Location: Remote This is a great opportunity to build a career in the SAP SD domain. Interested candidates looking to grow in SAP SD are encouraged to apply. This role offers hands-on exposure to real-world SAP SD projects.
