Build P21 business rules without writing code.
Add the steps a rule should take, test it against real values, and generate a deployment-ready DynaChange package — in minutes, not days.
Now demoing with Prophet 21 distributors — no commitment required.
All four steps ran. Nothing was written to P21.
A rule is a list of steps
Look up a value, guard a condition, branch a path, write a field, finish. Every step reads as a sentence, so the people who own the process can review the rule — then compile it to production-ready code.
How it works
From idea to deployed business rule in four steps.
Start
Pick the P21 window the rule fires on, or describe what you want in plain English and let the copilot draft the steps.
Add steps
Build the rule one step at a time — look ups, conditions, calculations, branches, emails and field writes. Reorder them as the logic changes.
Test
Enter the values the rule reads and run it. The trace shows what every step did and whether the save is allowed. Nothing is written to P21.
Compile & deploy
One click generates the DLL, the DynaChange configuration XML and an install guide — a complete deployment package.
Everything you need to build rules
A complete platform for creating, testing, and deploying P21 DynaChange rules — no C# required.
Step Builder
Sixteen step types, from look ups and guards to loops, branches and emails. Each one reads as a sentence in the rule's outline.
Test Before You Deploy
Run the rule against values you supply and read a step-by-step trace of what happened. Queries, requests and emails are stubbed — nothing reaches P21.
AI Copilot
Describe the rule in plain English and get a draft set of steps to review, edit and test. You stay the author — the copilot just does the typing.
One-Click Compilation
Generate deployment-ready DLLs instantly with Roslyn-powered compilation and detailed error diagnostics. Read the generated C# any time.
P21 Field Integration
Sync field metadata directly from your Prophet 21 environment. Searchable field catalog at your fingertips.
Multi-Tenant Workspaces
