Task orchestration across multiple systems

The implemented solution is based on NETGRIF Application Engine. The solution is a process-driven application, where every integrated system is a separate process of the application. Tasks created directly in the application are also implemented as a process, capturing the whole life cycle of a task.


The application provides a dashboard with statistics about a user’s tasks from the integrated systems and those created internally. The dashboard summarizes a count of critical and all tasks for a logged user for every integrated system. A team leader has, in addition to his own dashboard, a secondary dashboard with information about team members’ tasks.


Every task in the application is an instance of the integrated system. Every system has a view with all its available tasks assigned to a logged-in user. A user can click on a task and reveal more detailed information on the tasks provided by the source integrated system. The task contains a button to redirect a user directly to the task in the source system itself.
If the source system is a web application, the task is opened in a new browser tab ptherwise, an instruction is sent to the client OS to launch an appropriate application.


The application’s internal task management allows users to create tasks directly in the application. For more convenient task management within teams, a task can be created from email communication. When an email is sent to a specific application email address, the application reads the email, parses it, and creates a new instance of a task. The sender is set as an author of the task and all users stated in the email recipients are assigned to the task. The application is connected to Microsoft Exchange server via IMAPS and STMPS protocols.


The application is connected to the Microsoft Active Directory for user management via LDAPS protocol. For better user experience the application enables Single Sign-On through Kerberos protocol. The customer’s employees use AD with Kerberos to log-in into Windows OS on their devices and so users are automatically logged in into the application.


Integration between the application and external systems is implemented with help of SAP Platform Orchestration. The application sends requests for data to SAP PO and based on the request’s parameters the request is forwarded to an appropriate source system. Integration with SAP PO is implemented via HTTPS protocol and RESTful web services.


Task updating requests can be created by a user of the application on-demand or via a cron job, often triggered in nightly hours. The newly created request is added to the queue and waits for free resources to be processed further. A resource is the application capacity of processing requests simultaneously, the throughput of the deployed network, availability of source system, and SAP PO, and more. All resources are monitored by the application and SAP PO in real-time to ensure the fastest handling of the requests.
