SAP ABAP Inventory REST APIs

@Proolancer

With 14+ years of experience in developing enterprise-grade solutions, I can definitely deliver on your SAP ABAP Inventory REST API project requirements. My extensive knowledge of .NET Core, Angular, and other relevant technologies make me equipped to create clean and modular code in ABAP for ECC, ensuring efficient execution for your endpoints. I have a deep understanding of RESTful architecture and have previously built secure API integrations with external systems, which is a key aspect of this project. I can set up the API-key validation in the leanest manner possible while maintaining top-notch security. Moreover, my familiarity with OData/REST builds will facilitate seamless integration between your MM figures and the database - making certain every call returns accurate JSON structure that matches the data. Keeping performance at the forefront, I'll ensure all endpoints deliver within 2s response time on your QA system. What sets me apart is my relentless pursuit of measurable outcomes - be it superior UX, faster load times or automated workflows. In line with this approach, I'll provide comprehensive documentation along with a demo script for each endpoint; completing the project only once you're satisfied with its alignment to your needs.

Hello, I’ve reviewed your requirement to expose MM inventory data from ECC/S4 via five lightweight REST endpoints (current inventory, below-minimum, non-moving, valuation, on-hold/rejected). This is a straightforward, well-scoped job and I can deliver it as clean, class-based ABAP exposed via ICF/Gateway with API-key protection and a Postman collection for validation. Quick confirmations before I prepare a fixed SOW and ETA 1️⃣ ECC or S/4? (I’ll adapt code patterns and table usage accordingly.) 2️⃣ API-key storage preference — custom validation table (recommended) or SICF service handler logic? 3️⃣ Sample plant(s)/storage location(s) you’ll use for QA so I can test expected payload sizes and tune queries. Once you confirm the three quick points and grant sandbox access, I’ll prepare the concise one-page SOW (scope, milestones, cost) and start immediately.

Hello, I have strong experience in ABAP for ECC and S/4 environments, including building REST and OData services for inventory, MM reporting, and custom integrations. I have worked on multiple RICEF objects, MM-related reports, stock analysis, valuation reports, and CDS-based data extractions. I also have hands-on experience exposing ABAP class-based services through ICF/Gateway with JSON output, API-key validation, and secure lightweight endpoints. I can deliver the required five REST endpoints with clean, modular ABAP classes, proper API-key checking, and accurate MM data fetch logic. I am comfortable working with inventory, non-moving stock logic, valuation data, and hold/rejected materials. I can also provide documentation and a Postman collection for easy testing. My code is optimized for performance, and I can ensure each service responds within the required limits on QA. I can start immediately once sandbox access is provided. Thank you.

@coretus

Hi there, I’ve worked with ABAP on ECC/S/4, MM reporting, and REST/OData services, so exposing your MM inventory via lightweight JSON endpoints is a very natural fit. I can deliver the full set of services, documentation, and demos within 5 - 7 days from kickoff, assuming sandbox access and sample plants/storage locations are ready. Happy to jump on this and align the JSON schema and selection logic with how you currently view MM reports. Best regards, Anil | SAP ABAP (ECC/S/4) | REST/OData

@josephfryda

Hi I have experience in Rest API. I have already made OData to create purchase order in SAP S/4. I have also made a huge project in rest API to mange bid invitation in sap SRM system. I will create a project in SEGW and expose it in your gateway platform so you will be able to consume this ODATA via potsman. I will use as possible sap standard function to read/create inventory movement. I will also provide a detailed specification of all the Odata

@sauravap6

Relevant Previous Integration Projects: • HABALL Integration: ABAP-based invoice posting via HTTP APIs, JSON handling, and ALV preview. • SAP e-Invoicing (FBR): CPI + ABAP flows for VAT/e-invoice submission, QR generation, and response management. • Concur → SuccessFactors: CPI interface to pull Concur data and post TimeType entries to SF (OData v2). • SAP CI/BTP Integrations: REST services with OAuth, assertion tokens, and secure payload exchange. • Custom ECC REST Services: ICF-based JSON APIs for material, stock, and SD order insights. • Asset QR Service: Adobe Form + custom API for QR-based asset identification. These demonstrate strong capability in secure, optimized SAP-side API development. Understanding of Requirements You need five REST endpoints delivering JSON for: current inventory, below-minimum parts, non-moving parts, total valuation, and hold/rejected stock. All endpoints must be API-key secured, class-based, performant, and aligned with MM tables (MARD, MARC, MBEW, MSEG, MKPF, QALS). Approach • Build lean ICF/Gateway REST architecture • API-key validation via Z-table or handler • Class-based handlers with `/UI2/CL_JSON` • Optimized DB reads with proper indexing • Provide Postman and URL scripts • Deliver full documentation Turnaround Complete delivery in 6–8 working days after sandbox access. Ready to start immediately.

@Ashutosh19923004

Thank you for the clear scope. This fits very well with my experience in MM reporting and REST/OData integrations on ECC and S/4HANA. I have designed and implemented multiple class-based ABAP services exposed via ICF / SAP Gateway to external systems (typically for inventory, valuation, and logistics KPIs), returning lightweight JSON and secured with custom API-key or token tables. For your requirement, I would: Implement a modular service class with separate methods for each of the five endpoints (current stock, below-min, non-moving, valuation, on-hold/rejected). Use standard MM tables (e.g. MARD, MBEW, MARC, MCHB) and existing stock logic to ensure figures reconcile with standard SAP reports. Serialize responses to JSON (e.g. /UI2/CL_JSON) and protect all calls with an API-key header validated against a custom ZAPI_KEY table or a lean SICF handler. Optimise SELECTs and buffering to keep response times under your 2 s requirement on QA. Deliverables will include: Transportable ABAP classes and ICF/Gateway configuration Technical documentation (endpoints, parameters, JSON structures) Postman collection / cURL scripts for each endpoint Estimated turnaround: approx. 4–5 working days after sandbox access and confirmation of key MM fields (plants, storage locations, status logic).
