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
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.
The WSDL documentation was frequently revised, resulting in inconsistencies. Azati engineers manually adjusted configurations to correctly handle incoming and outgoing messages.
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.
