Asynchronous SAP Transaction Adapter Using IDoc Conversion and tRFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adapters for handling outbound asynchronous transactions to SAP applications do not support guaranteed once-only delivery using J2EE Connector Architecture (JCA) calls for local transactions and cannot handle multiple transactions simultaneously.
Innovation Solution
A method and system that convert a service data object (SDO) containing transaction data to an intermediate document (IDoc) for delivery to an SAP application using the tRFC protocol, with associated transaction identifiers (TIDs) for processing and confirmation, ensuring once-only delivery and managing multiple transactions asynchronously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If current adapters use asynchronous transaction processing to SAP applications, then processing speed is improved, but guaranteed once-only delivery cannot be ensured
Solution Approach 1:
The patent implements feedback mechanisms through acknowledgment messages and transaction status tracking. The system sends acknowledgment messages back to the sender and maintains transaction state information to verify once-only delivery, resolving the contradiction between asynchronous speed and delivery reliability.
Solution Approach 2:
The patent applies preliminary action by pre-establishing transaction identifiers and preparing acknowledgment protocols before transaction processing. This ensures that delivery guarantees are built into the transaction framework from the outset, maintaining reliability while enabling asynchronous processing.
2Productivity
If multiple transactions are processed simultaneously, then productivity is improved, but transaction management complexity increases
Solution Approach 1:
The patent segments transactions into distinct units with unique identifiers and manages them through separate processing channels. This segmentation allows multiple transactions to be processed simultaneously while maintaining clear boundaries and simplified management through structured transaction objects.
Solution Approach 2:
The patent introduces intermediary transaction management components that act as mediators between multiple concurrent transactions. These intermediaries coordinate transaction processing, track statuses, and manage resources, enabling high throughput while reducing overall system complexity through centralized coordination.
3Ease of operation
If J2EE Connector Architecture is used for local transactions, then ease of operation is improved, but support for guaranteed delivery is lost
Solution Approach 1:
The patent creates a universal transaction management framework that combines J2EE Connector Architecture capabilities with guaranteed delivery mechanisms. The system provides multi-functional support for both asynchronous and synchronous transactions, local and remote communications, while maintaining consistent delivery guarantees across all transaction types.
Data Source
AI summary
An apparatus, system, and method are disclosed for managing outbound transactions in a service oriented architecture. An execution module is included to receive a J2EE Connector Architecture (“J2C”) execute command associated with a service data object (“SDO”) containing transaction data from a client application. A conversion module is included to convert the SDO to an Intermediate Document (“IDoc”). A transmission module is included to transmit the IDoc and an associated transaction identifier (“TID”) to an SAP application using a transaction Remote Function Call (“tRFC”) protocol for processing the embedded transaction data. A confirmation module is included to transmit the SDO updated with the TID to the client application in response to acknowledgement of receipt of the transaction data from the SAP application.
