Workflow Optimization
The data bus significantly reduced time spent on document generation and management, improving efficiency across departments.
Technologies used
Apache Camel
Spring
Groove
Motivation
The client faced inefficiencies in document generation and management, causing delays, errors, and increased administrative workload. Azati’s task was to create a middleware data bus to integrate SAP ERP with the document generation system, automate document workflows, and ensure seamless data exchange, while handling different formats and business logic requirements.
Main challenges
Challenge 01
Lack of Experience with the Document Management Software
This was Azati’s first project with the client’s document generation system. The team spent time studying the software, understanding protocols, and planning business logic to ensure proper workflow integration.
#1
Challenge 02
Inaccurate and Evolving Web Services Documentation
The WSDL documentation was frequently revised, resulting in inconsistencies. Azati engineers manually adjusted configurations to correctly handle incoming and outgoing messages.
#2
Challenge 03
Communication Gaps Between Multiple Teams
The project involved Azati, the document system team, and the customer team. Misalignment caused delays, which were resolved through weekly coordination meetings and sprint reviews.
#3
Our approach
Comprehensive Planning
The team studied the documentation, organized workflows, and defined a clear development roadmap to integrate the systems efficiently.
Middleware Development with Apache Camel
Using Apache Camel and CXF, the team built SOAP web services to enable robust, scalable communication between SAP ERP and the document generation system.
Advanced Data Processing
Custom algorithms were implemented to convert XML to JSON, enrich messages with required meta-information, and route them correctly to downstream systems.
Security and Error Handling
Authentication mechanisms and advanced error validation were implemented to ensure secure data transfer and detailed logging for troubleshooting.
