How to Use Epicor Application Studio for Low-Code Customizations

Modern ERP systems must be flexible enough to adapt to business-specific workflows, without becoming a tangled mess of code. That is where Epicor Application Studio stands out. Designed for the Epicor Kinetic framework, this low-code development platform empowers users to customize applications through drag-and-drop tools, eliminating the need for deep technical expertise.

In this guide, Epicforce Tech walks you through everything you need to know to confidently use Application Studio to tailor Epicor to your organization’s needs, without compromising upgrade compatibility or maintainability.

What Is Epicor Application Studio?

Application Studio is Epicor’s built-in, low-code customization environment for modifying forms, pages, and business logic in Epicor Kinetic. It replaces the older customization tools like Classic Customizations and Layered Customizations.

Built on modern web technologies (Angular and .NET Core), Application Studio allows you to:

• Customize UI elements with drag-and-drop tools
• Create business rules without writing code
• Deploy customizations safely across environments
• Leverage reusable components via customization layers

Why Use Application Studio?

At Epicforce Tech, we recommend Application Studio to clients for five key reasons:

1. No-code to low-code flexibility
   Even non-developers can modify user interfaces or business flows. Developers can dive deeper when needed.
2. Upgrade-friendly
   Unlike legacy customizations, Kinetic layers in Application Studio remain intact during version upgrades, reducing rework.
3. Improved governance
   Changes are modular, layered, and auditable. This is ideal for compliance and audit trails.
4. Scalable across teams
   Different teams can customize their experience without overwriting the base code or affecting global settings.
5. Faster development lifecycle
   Rapid deployment, testing, and rollback features mean changes are implemented faster and safer.

Key Concepts in Application Studio

Before jumping in, understand the core components:

Layers

Customizations are built in layers. This means you can have a base form, and then add different layers for specific users, companies, or environments. You avoid duplicating or corrupting the original logic.

Events

These are triggers like field changes, button clicks, or data loading. You define what should happen when using these.

Rules

Rules are the logic behind events. For example, “If the order quantity is above 100, show a warning.”

Expressions

Used within rules, expressions are logical formulas that guide app behavior.

Widgets

Widgets are reusable UI components like text boxes, drop-downs, grids, or buttons. You can drag and drop these onto forms.

Step-by-Step: Customizing Epicor with Application Studio

Here’s how to get started:

Step 1: Launch Application Studio

1. Navigate to the form or page you want to customize in Epicor Kinetic.
2. Click the gear icon and select Application Studio.
3. Choose or create a new layer (for example, “SalesEntry_Custom”) for your customization.

Step 2: Add Fields or Controls

1. Use the toolbox to drag fields, text boxes, labels, or buttons onto the canvas.
2. Resize and position elements visually.
3. Use Bind to DataView to link a widget to Epicor database fields.

Step 3: Define Business Rules

1. Go to the Event Handler tab.
2. Choose a trigger event (such as OnClick or OnChange).
3. Add an action like “Set Field Value,” “Show Message,” or “Run Function.”
4. Apply logical conditions using expressions (for example, [OrderQty] > 100).

Step 4: Preview and Test

1. Click Preview to test the customized screen.
2. Validate all user interactions and edge cases.
3. Use browser dev tools to inspect issues if any logic doesn’t work as expected.

Step 5: Save and Deploy

1. Save your layer.
2. Promote it from sandbox to production or assign it to specific users.
3. Monitor logs and user feedback.

Real-World Use Cases

• Streamline Sales Order Entry
  Add custom buttons that auto-calculate discounts based on quantity tiers.
• Improve Warehouse Accuracy
  Color-code rows in a grid if inventory is below minimum stock levels.
• Enforce Business Rules
  Hide or disable specific fields based on user role or customer type.

Tips to Make Your Customizations Upgrade-Safe

As Epicforce Tech consultants often advise, good customization is about stability and scalability. Follow these best practices:

• Use separate layers for each role or department.
• Document all changes in a central repository with screenshots and logic descriptions.
• Avoid duplicating core functionality. Instead, extend existing widgets or workflows.
• Test in a QA or sandbox environment before pushing to production.
• Use naming conventions that reflect form, layer, and purpose (for example, CustomerForm_CreditCheck_Admin).

Common Mistakes to Avoid

1. Over-customizing standard forms
   Stick to what is necessary. Too many changes can reduce maintainability.
2. Hardcoding values
   Use expressions or data fields instead of hardcoding values like dates, limits, or codes.
3. Skipping documentation
   Future you (or your team) will thank you for notes and screenshots.
4. Ignoring user feedback
   Always involve end users in testing before rollout.
