About the technology
X++ in Dynamics
X++ is the object-oriented programming language behind Microsoft Dynamics AX and Dynamics 365 Finance and Operations. It is used to extend finance, supply chain, commerce, project management and human resources processes inside the ERP system. Its syntax resembles C#, while its data access and business logic are closely tied to the Dynamics application model.
Business Applications
X++ specialists turn operational requirements into maintainable ERP functionality. Typical work includes:
- Extending purchasing, sales, inventory and accounting workflows
- Creating forms, reports, batch jobs and business events
- Building data entities for imports, exports and recurring integrations
- Supporting localization, tax logic and company-specific processes
These deliverables help organizations standardize core operations without forcing every process into an external application.
Tools and Ecosystem
Modern X++ work commonly uses Visual Studio, Application Explorer, the Dynamics 365 development environment and Azure DevOps. Professionals work with tables, extended data types, classes, forms, queries, security roles and data entities. They also use SQL knowledge, Power Platform components, OData, REST services and integration patterns around Dynamics 365.
When to Bring Expertise
Companies often need freelance X++ expertise during ERP implementations, upgrades, rollouts and urgent backlog work. It is also valuable when internal teams must replace legacy overlayering with supported extensions or improve slow batch processing. Signs include repeated manual work, fragile customizations, failed data migrations or integrations that do not provide reliable error handling.
What Strong Specialists Deliver
Strong professionals understand both X++ code and the business processes it changes. They use extension-based customization, Chain of Command and event handlers where appropriate, while keeping upgrades in mind. They test security, performance, data integrity and legal-entity behavior instead of validating only the happy path. Clear documentation and disciplined source control make their work easier to operate.
Collaboration in Dusseldorf
Organizations in Dusseldorf may use X++ specialists for manufacturing, logistics, retail, finance or international operations. Remote delivery works well for backlog development, code review and integration design when access, environments and decision paths are prepared. On-site sessions can help with process discovery, workshops and user acceptance, while German and English communication may both matter across local and global teams.
Frequently asked questions
Key details about X++, drawn from the questions we get asked most.
X++ is used to customize and extend Microsoft Dynamics AX and Dynamics 365 Finance and Operations. It supports business logic, forms, reports, workflows, batch processing, data entities and integrations across ERP processes.
X++ is closely integrated with the Dynamics application model, data dictionary and security framework, so it is usually more suitable for native Finance and Operations changes than a general-purpose language. C# remains useful for external services, Azure components and integrations, while Power Platform can cover selected low-code scenarios.
A capable X++ specialist often works with Dynamics 365 Finance and Operations architecture, SQL concepts, Visual Studio, Azure DevOps and data management. Experience with OData, REST, Power Platform, security roles and performance troubleshooting is also valuable.
The right level depends on the work rather than a fixed number of years. A focused report or data entity may need a specialist familiar with the relevant module, while an ERP rollout, upgrade or major refactoring needs someone who can assess architecture, extensions, integrations and operational risk.
Yes. X++ delivery can be remote when the specialist has secure environment access, clear requirements and reliable communication with product owners and functional teams. On-site workshops in Dusseldorf can still help with process mapping, training and acceptance testing.
Clarify the Dynamics product version, modules, environments, deployment process and customization approach before work starts. A strong X++ professional should also ask about data volumes, integrations, security, localization and upgrade constraints.
Review whether the implementation follows supported extension patterns, has focused tests and handles failures clearly. Good X++ work also protects performance, security and data integrity, includes useful documentation and avoids changes that create unnecessary upgrade effort.
X++ is used in both product generations, but the development and deployment model differs. Dynamics 365 Finance and Operations places more emphasis on extensions, Visual Studio, lifecycle services and cloud-ready integrations, while older Dynamics AX projects may contain legacy overlayering and MorphX-based customizations.
