An Introduction to Scheer PAS

Scheer PAS is a platform with a unique Process iPaaS (Integration Platform as a Service) approach. The clear focus on process-driven integration sets it apart from other iPaaS solutions: While iPaaS generally enables the integration of applications, data, and services, Scheer PAS Process iPaaS embeds this integration within the context of business processes. The process-oriented approach of Process iPaaS is designed to make complex processes more efficient, and achieves optimized automation and better business outcomes.

Our Model2Execute Approach

Scheer PAS supports developers from initial process and execution modeling to server deployment, administration and process/error analysis.

• Both, the pure business processes and their execution (including data models, integrations, APIs and UIs), are created in the Designer, and developers are continuously supported by a validation process running in the background. Once the modeling is complete, developers can easily compile the business process into an xUML service, deploy it to the server and run it.

• APIs can be secured via API Management and made accessible to specific groups of people.

• The services and the platform can be managed via the administration components, and various options for process and error analysis are available.

In short: Scheer PAS allows you to develop, execute and manage integration workflows in a process-driven way.
It embeds the integration of applications, services and data into a process view to achieve an optimal business outcome when automating complex business processes.

Scheer PAS Components

The Scheer PAS platform consists of several core and a couple of supplementary components.
The core components include the Designer, API Management and Process Mining. These components are supplemented by other useful tools such as container and user administration, the Analyzer and Log Analyzer for troubleshooting and debugging, and others.
Depending on the user rights managed in our user and identity management, users access the PAS components released for them directly from the Scheer PAS portal. While working with Scheer PAS, all these components interact seamlessly with each other:

To help you understand how all these components work together, we will explain this overall concept of Scheer PAS in more detail.

Designer

The Designer is at the heart of working with Scheer PAS. You can use this modeling tool to create both, UI-based and purely integration-focused applications.
A simplified version of the BPMN standard is used for asynchronous process modeling, while the UML standard is used for synchronous execution modeling.

In addition to processes and execution diagrams, you can also create data structures and forms for UI-based process steps in the Designer. If Low-Code modeling options are no longer sufficient, the service can also be extended using the Pro-Code approach. Various adapters and connectors for integrating third-party systems are available for integration processes.

During the modeling process, continuous validation and compilation run in the background of the Designer to identify potential problems and update the integrated test environment.

API Management

In API Management, you can manage your APIs and API requests. It is situated between the API and the client and enables you to apply different policies, enforcing them as runtime rules for each managed API request made. API Management also allows to control visibility, security, and versioning of APIs. In addition, API management supports versioning of plans and clients, ensuring that changes to these elements are tracked and maintained without affecting the original configuration.

With the API Developer Portal, you can grant customer developers access to your APIs. It also gives you full control over access to your APIs: Determine for yourself who can use your APIs - only members of a specific organization, the users of API Management or all (anonymous) visitors to the developer portal.

Administration Tools

After deployment, developers and administrators can easily manage the services via the PAS Administration. The administration gives them access to the container statuses, endpoints, logs, and settings of deployed xUML and PAS platform services. It is also possible to access and manage persistent state objects.

In the User Management, administrators can create and deactivate users and manage their permissions, roles and profiles. The user management is also connected with the Identity Management, which is based on Keycloak. This open source identity and access management solution allows to implement various authorization concepts, such as SSO or connections to third-party systems.

Analysis Tools

Various tools support users of the platform with analyzing their services, identifying faulty implementations or using process data for the further development and optimization of services:

• Automatic notification in case of errors: In the xUML Service Monitor, developers can define events for the individual xUML services which, when they occur, alert a specific group of people.

• Troubleshooting:

  • Service logs displayed in the Log Analyzer (based on OpenSearch) can provide initial indications of the causes of errors. Access to the log files can be very helpful for troubleshooting. If a problem occurs with an xUML service, each incident is recorded in chronological order. Various search parameters can also be defined.

  • The Analyzer is a helpful tool for tracking exactly where an error occurred in a service. You can import services into the Analyzer, and establish a connection to the PAS platform. The Analyzer then supports developers with runtime analysis, troubleshooting of distributed systems and regression testing. The Analyzer consists of three tools to help with the above: a Trace Analyzer, a Log Analyzer, and a Regression Test Tool.

• Process Analysis: Process Mining allows you to analyze tracing information stored in the service context on the PAS server by graphically displaying the processes performed. This makes it possible to discover and monitor processes, recognize bottlenecks and generally identify inefficiencies and areas for improvement.

Some Real-Life Examples

• Complete Process Acceleration
  A large pharmaceutical and healthcare distribution and logistics specialist faced huge challenges lacking any connections between customers and suppliers. Isolated legacy solutions could not meet the modern enterprise problems with an adequate solution.
  Scheer PAS established a central data hub through SAP and EDI communication and implemented standardized interfaces for SAP-RFC, EDIFACT, X12, XML, flat files, FTP, SMTP, AS400/SDS, multibyte and other - which led to a huge acceleration of the company’s processes.

• Unified and Integrated IT Systems
  A British private bank experienced operational inefficiencies and increased costs due to a non-integrated system landscape and frequent process disruptions. Moreover, poor integration with third-party systems, like payment processors, led to delays and potential revenue losses.
  Scheer PAS established the development of a central, highly available and load-safe integration platform that can also be used to integrate third-party systems. This also enabled the integration and automation of debit and card processors as well as the integration of software for recognizing speech patterns.

• Reduced operating costs and ensured flexibility through process digitization
  A customer from the manufacturing industry was confronted with the problem that outdated SAP systems were hindering the company's ability to innovate and progress, as the overview of customers and products was not guaranteed.
  Scheer PAS created a single data hub for all sales processes, the core components of which are hosted in the customer's hybrid cloud. The new data hub allows the customer to use his existing SAP system and enables standardized trading for B2B and B2C.

• e-Invoicing
  Due to changes in legal regulations, electronic invoicing has been mandatory for most business transactions since January 2025. A customer from the advertising industry was unable to retrieve data from the internal ERP system and had to create the visual representation of the invoices, as well as the validation and dispatch manually.
  With Scheer PAS, an automatic export of invoice data from the internal ERP system was realized. The data is then converted to XRechnung, validated and automatically sent to the customer.
