Democratizing P21 rule development
ERP Logic Studio was born from a simple frustration: creating business rules in Prophet 21 shouldn't require a C# developer. We're building the tools to change that.
Business rules shouldn't require developers
P21's DynaChange framework is powerful, but creating rules requires C# programming expertise. This creates a bottleneck — business analysts who understand the rules can't implement them, and developers who can code them don't always understand the business context.
Rules the business can read
ERP Logic Studio bridges this gap with a no-code platform. Business analysts build a rule as a list of steps — each one reads as a sentence — and test it against real values before it ships. The platform handles the C# code generation, compilation, and deployment packaging automatically.
Product vision
We're building the future of P21 customization, one phase at a time.
Template-Based Rules
Pre-built templates that generate production-ready DynaChange C# code and deployment packages.
Step Builder
Build a rule as an ordered list of steps, then run it against real values and read the trace before anything reaches P21.
AI-Assisted Rule Creation
Describe a rule in plain English and get a draft set of steps to review, edit and test — or import an existing C# rule and let the copilot translate it.
Web Rules
Generated web pages that P21 opens from a window — read the fields, show a form, write the values back.
Built for trust
Enterprise-grade architecture you can trust with your business rules.
