Basic code's of ABAPBasic code's of ABAPNine standalone ABAP reports built around REUSE_ALV_GRID_DISPLAY and CL_SALV_TABLE, covering display, screen validation, spool creation, Excel upload and table maintenance without SM30. One report raises and catches a custom exception class with RAISE EXCEPTION and TRY/CATCH, the class-based mechanism error handling names for ABAP; another submits a job to spool, converts it to PDF with CONVERT_ABAPSPOOLJOB_2_PDF and exports a CL_SALV_TABLE result to Excel before mailing both, producing document output from spool rather than Form Builder.RakeshZore, published 2025-09-30
Beginners Guide to Advanced Event MeshBeginners Guide to Advanced Event MeshA scenario-by-scenario walkthrough of Advanced Event Mesh, run through Cloud Integration iFlows: publishing and consuming queue messages, dead message queue setup with retry counts and acknowledgment modes, direct messages, durable topic endpoints and selectors, time-to-live, REST Delivery Points, replay by replication group message ID, parallel consumers with partition keys, and the request-reply pattern. Each scenario is built and verified step by step against a Solace trial account standing in for AEM.PriyankaChak, published 2025-07-24
Effective Axios Error Logging for Robust SAP IntegrationsEffective Axios Error Logging for Robust SAP IntegrationsTwo logged failures printed side by side, and the point is made by looking at them: one tells you what went wrong and one does not. Axios buries the useful part of an HTTP error, and this is what to unwrap before logging it from a CAP service.Sahil2508, published 2025-08-31
How to create a Purchase Order through BAPI in the SAP through program ( SE38 ) T-CODE .How to create a Purchase Order through BAPI in the SAP through program ( SE38 ) T-CODE .Walks through creating a purchase order from an ABAP report (SE38) by filling the BAPIMEPOHEADER/BAPIMEPOITEM structures and their X-indicator counterparts, then calling BAPI_PO_CREATE1 within the same session. Its error handling centres on the BAPIRET2 return table: looping over entries typed E or A, skipping BAPI_TRANSACTION_COMMIT when one is found, and displaying the returned message text rather than assuming success once the function module returns.chandu_kumar_badukuri, published 2025-12-18
How to subscribe or fetch data from solace to CPI using AEM Adapter : part-5How to subscribe or fetch data from solace to CPI using AEM Adapter : part-5Closes a series on event-driven architecture with Solace by detailing the subscriber side of an iFlow in Cloud Integration: an advanced event mesh adapter feeds an exception subprocess, and a Groovy step classifies each failure as recoverable, left to Solace's own retry, or non-recoverable, answered with a custom property that tells Solace to stop retrying before the message reaches an escalation layer. The escalation layer names email, ServiceNow and Loggly as destinations without explaining any of them.pavanKolla, published 2025-08-03
Making the Case for Enhanced REST Adapter in SAP Integration SuiteMaking the Case for Enhanced REST Adapter in SAP Integration SuiteCatalogues what SAP Integration Suite's native HTTP adapter supports for authentication (Basic, OAuth 2.0 client credentials and client certificates on the sender; OAuth 2.0 client credentials and SAML bearer assertion on the receiver) and for error handling (retry on HTTP failure only, with no pattern-based retry, failure queues or dead-letter queues), and that it has no OpenAPI import or export. Three worked scenarios, FedEx shipment tracking, Avalara AvaTax and SAP Ariba's operational reporting API, name what that leaves to Groovy scripting: the other OAuth 2.0 flows, gzip and multipart payloads, and pagination that chains a nextPageToken by JSONPath, which is the case the piece makes for the third-party Advantco REST Adapter.peter_ha3, published 2025-07-14
Migration Journey from MuleSoft to SAP Integration Suite (CI)Migration Journey from MuleSoft to SAP Integration Suite (CI)Maps MuleSoft Anypoint's error handling onto SAP Integration Suite: the Global Error Handler and MuleSoft's built-in retries become Exception Subprocesses with scripted Groovy retry logic or JMS-based retry, since Cloud Integration has no automatic equivalent. MuleSoft's searchable logger text becomes Content Modifier headers and Groovy-scripted Message Log entries, correlated by application message ID and correlation ID for traceability across complex interfaces. The mapping is drawn from the author's own migration project across assessment, development and validation phases, and is explicitly flagged as not an SAP- or MuleSoft-approved design.Shailaja, published 2025-09-21
New tutorial for UI5 Middleware FE MockserverNew tutorial for UI5 Middleware FE MockserverA step-by-step tutorial accompanying a Devtoberfest session walks through @sap-ux/ui5-middleware-fe-mockserver across nine exercises: zero-config mock data generated from OData metadata, custom JSON datasets with consistent IDs and referential keys, JavaScript actions, multi-service and cross-service scenarios, tenant isolation through sap-client, returning 400/404/422/500/501 responses for UI error-handling tests, and offline end-to-end tests run with wdi5. A companion tool, ui5-middleware-odata-recorder, captures real backend OData traffic to generate the mock datasets used for offline replay.published 2025-10-14
Parallel Data Filtering and Dropbox Integration Using SAP Cloud IntegrationParallel Data Filtering and Dropbox Integration Using SAP Cloud IntegrationA step-by-step build of an integration flow in Cloud Integration: a Start Timer triggers the flow, a Parallel Multicast splits student records by gender through XPath filters, and each branch uploads its file to Dropbox over a Receiver Adapter authorized against a Dropbox app's OAuth2 credentials. An Exception Subprocess captures the error message and a Mail Adapter sends it over SMTP, centralizing error handling and an email notification for the whole flow.Vurumind03, published 2025-12-10
Calling the Sales Order (A2X) OData V2 API from BTP Using a Service Consumption ModelCalling the Sales Order (A2X) OData V2 API from BTP Using a Service Consumption ModelWalks through ABAP's Service Consumption Model for OData V2 in ABAP Development Tools for Eclipse: generating a client proxy from the Sales Order (A2X) API's downloaded EDMX, then using it from an ABAP console class to create a deep sales order with items, texts, partners and pricing elements, read it back and patch a field. The client itself is built the way HTTP clients describes for SAP BTP ABAP environment: a communication arrangement resolved through cl_http_destination_provider=>create_by_comm_arrangement, handed to cl_web_http_client_manager=>create_by_http_destination, reaching the inbound SAP_COM_0109 scenario configured on the SAP S/4HANA Cloud Public Edition side.Katsiaryna_Darapeika, published 2025-02-04

The sample class creates a deep sales order with an item, a text, a partner and a pricing element, reads it back, then updates a field guarded by its ETag.Katsiaryna_Darapeika, published 2025-02-06
Invoking Business Agent Foundation Agents from ABAP: A Step-by-Step GuideInvoking Business Agent Foundation Agents from ABAP: A Step-by-Step GuideWalks through calling a Business Agent Foundation agent's chat endpoint from an on-premise ABAP report: an OAuth 2.0 client profile configured in SE80/SOAUTH2_CLIENT with client-credentials grant against the service key, an HTTP (type G) RFC destination in SM59 bound to that profile, and an ABAP report using CL_HTTP_CLIENT=>CREATE_BY_DESTINATION to POST a JSON message to the agent's sendMessage endpoint and extract the reply by splitting the response string. The destination and client code are the same shape as any outbound REST call from ABAP; nothing here is specific to the agent service beyond the request body and URL.tanmay_0117, published 2025-11-26

How to use reserved words as property names in your OData service?How to use reserved words as property names in your OData service?Setting a CDS view alias to a reserved OData word, such as Number, fails compilation with 'NUMBER is a reserved word'. The fix for a RAP-based OData service is the @odata.property.name annotation: it lets the underlying CDS view keep a compiler-safe name (NumberInStock) while the $metadata EntityType still exposes the field as Number, shown against a products view and its generated EDMX.Andre_Fischer, published 2025-11-10
SAP Cloud Platform Backend service: Tutorial [12]: CDS : local: buildSAP Cloud Platform Backend service: Tutorial [12]: CDS : local: buildCompiling a CDS model locally with the cds command-line tool, installed from @sap/cds via SAP's own npm registry, before uploading it to SAP Cloud Platform Backend service: cds compile converts the model to CSN by default, --to edmx or --to edm produces the OData V2 or V4 metadata document, and --to hana or --to sql produces the database-specific definition files. It shows the local build catching an error the CDS editor's own validation misses — an entity with no key, valid CSN but invalid OData — before the same model reaches the server's compiler.CarlosRoggan, published 2019-04-15

Generating Adobe Form Using RAP framework OData ServicesGenerating Adobe Form Using RAP framework OData ServicesModels a RAP root view entity and consumption view over a custom sales-order table, built with ABAP CDS, and exposes it through a service definition and an OData V2 UI service binding. A separate SEGW project implements GET_STREAM to call an Adobe Form driver class and stream the rendered PDF back as the response, with a computed link field added to the CDS view so the UI can open it. The PDF is generated in the backend and returned to the calling program rather than sent straight to a printer.Megastar, published 2025-03-18
How to Perform Initial Loads from S/4HANA to Advanced Event Mesh with Odata PollHow to Perform Initial Loads from S/4HANA to Advanced Event Mesh with Odata PollWalks through building a Cloud Integration flow that polls the S/4HANA Business Partner OData API on a timer, splits the response into individual records, and publishes each as an event to Advanced Event Mesh through its adapter, with the topic set dynamically from a grouping property. Selects fields and expands associations with $select/$expand against an EDMX from the API Business Hub, and works around the OData V2 adapter's lack of JSON support by falling back to the HTTP adapter with an XML-to-JSON converter. Flags the trade-off: the pattern needs no backend change beyond activating the API, but the polled payload has to stay aligned with whatever event format the ERP pushes on change.AlexPfeil, published 2025-04-04
OData Deep Insert: Implementation and Real-Life ExamplesOData Deep Insert: Implementation and Real-Life ExamplesWalks through implementing OData Deep Insert on classic SAP Gateway: two entity types joined by an association in SEGW, and a redefined CREATE_DEEP_ENTITY method in the DPC_EXT class that unpacks the header and item payload and calls BAPI_SALESORDER_CREATEFROMDAT2 to create a sales order with its line items in one request instead of separate calls per item. Gives a sample JSON payload to test with Postman or /IWFND/GW_CLIENT and names the usual failure points — an unmapped association, a method that was never redefined, or a commit left out after the BAPI call.SRSATAPATHY, published 2025-09-15
S/4HANA公有云版的内部ABAP拓展S/4HANA公有云版的内部ABAP拓展Argues that S/4HANA Cloud public edition's in-app ABAP extensibility is still real ABAP development, just under stricter rules: developer extensions require ABAP Development Tools rather than SAP GUI transactions, data models are defined as CDS views instead of SE11 tables, business logic is a RAP behavior definition instead of a function module, and service exposure is an auto-generated OData service from a Service Definition instead of a hand-built RFC/BAPI. The piece walks a worked example — a Fiori app that triggers the Purchase Requisition API — through CDS, RAP, OData activation on SAP Gateway, and authorization via business catalogues, and frames the whitelist of released APIs and CDS views as upgrade-safety rather than a restriction.ArthurYang, published 2025-11-24

SAP Cloud Platform Backend service: Tutorial [11]: CDS : magic: key: generationSAP Cloud Platform Backend service: Tutorial [11]: CDS : magic: key: generationExplains CDS's UUID key type: giving a key property UUID gets its value generated automatically instead of a hand-picked unused number, as data modelling lets an element's type do, at the cost of a 36-character value unfit for a user-facing display. It then works out how that generated value is addressed in a single-entity read URL — bare brackets in OData V4 against the guid'...' literal V2 requires — citing the OData specification for the difference.CarlosRoggan, published 2019-03-15

Communicate from a Java Application to ABAP via WebSocket RFC using JCo - Migration GuideCommunicate from a Java Application to ABAP via WebSocket RFC using JCo - Migration GuideWalks a JCo setup from classic CPIC-based RFC to WebSocket RFC: swap the application- or message-server logon properties for jco.client.wshost and jco.client.wsport, and implement DestinationDataProvider's getSSLContext (and, for mTLS, getClientCertificate) since the new connection runs over TLS. It covers building the PKI trust on both sides — a local PKCS12 keystore for the Java side, STRUST's SSL-Server Standard certificate exported and imported for mutual trust on the ABAP side — and notes that on BTP, JCo paired with the Destination service already implements this via the Connectivity service, so the custom SSLContext work can be skipped there.simon_luser, published 2025-01-21
