Individually, these tools offer strong functionality. But when linked together, they form the foundation of intelligent, data-driven automation within Epicor.

In this guide, Epicforce Tech explains how to connect BAQ outputs with BPM logic to trigger real-time decisions, automate compliance checks, and reduce manual effortall while ensuring your ERP remains maintainable and upgrade-safe.

What Is a BAQ?

A Business Activity Query (BAQ) is Epicors built-in querying tool that allows you to:

• Retrieve live ERP data from one or more tables

• Perform calculations, aggregations, and filtering

• Create parameter-driven queries

• Feed data into dashboards, trackers, and BPMs

BAQs are flexible and require no external SQL coding. They are essential for visibility, reporting, and user-specific analytics.

What Is a BPM?

Business Process Management (BPM) in Epicor allows you to embed logic into standard system workflows such as:

• Validating field values

• Sending alerts or emails

• Blocking or modifying records before save

• Calling external integrations

• Triggering follow-up workflows

BPMs can be configured with condition widgets, custom code blocks, and interaction with user input.

Why Connect BAQs to BPMs?

Connecting BAQs to BPMs enables logic that reacts to live system conditions. This allows businesses to:

• Alert users before a risky transaction occurs

• Block transactions when live data violates rules

• Look up related records dynamically during a save action

• Calculate context-aware thresholds

• Ensure up-to-date decision-making using live system state

Instead of hardcoding values or relying on static logic, you can use a BAQ to drive real-time decisions based on accurate, dynamic data.

Common Use Cases: Linking BAQ to BPM

1. Credit Limit Validation
   Use a BAQ to check the customers open AR balance and sales order total. Trigger a BPM warning if it exceeds their credit limit.

2. Supplier Status Check
   Query the latest compliance status of a vendor and prevent PO release if certifications have expired.

3. Inventory Availability Warning
   Use a BAQ to confirm on-hand quantity before saving a job or transfer order. Trigger a soft warning or block based on business rules.

4. Customer History Insights
   Before closing a case or quote, query past purchase history or outstanding issues and prompt the user to review.

5. Workflow Routing
   Use a BAQ to identify the correct department or user group dynamically and route approval or tasks accordingly.

How to Link BAQ to BPM: Step-by-Step

Step 1: Build the BAQ

• Identify the data your BPM logic will need

• Use table joins, calculated fields, or filters to narrow results

• Add input parameters if you want to pass a value (such as CustomerID or OrderNum)

• Save and test the BAQ independently

Best practices:

• Prefix your BAQ name for clarity (e.g., BPMCheck_CreditLimit)

• Use calculated fields for logic, not just raw data

• Keep the BAQ lean for performance

Step 2: Create or Edit the BPM

• Navigate to the Method Directive Maintenance screen

• Choose the method tied to your process (for example, SalesOrder.Update)

• Select a pre-processing or post-processing directive depending on when you need logic to execute

Step 3: Use the Execute BAQ Widget

• Drag the Execute BAQ widget into your BPM workflow

• Select the BAQ you created in Step 1

• Map the input parameters from your current context (e.g., link CustomerNum from Sales Order)

Step 4: Evaluate the BAQ Output

• Use a Condition widget to inspect the BAQ results

• Examples:

  • If credit limit exceeded: show a warning

  • If status is Blocked: cancel the transaction

  • If availability is low: prompt user for confirmation

You can use Count, Field value, or calculated expressions to evaluate results.

Step 5: Take Action

Depending on your condition evaluation, take one or more of these actions:

• Show a Message Box

• Set a field value automatically

• Block or allow the transaction

• Send an email to a supervisor

• Create a task or event in another module

Tips for Performance and Maintainability

• Avoid complex BAQs inside high-frequency transactions

• Use indexed fields in BAQ filters

• Return only necessary columns

• Limit result set to 1 row when possible

• Use BPM logging selectively during testing only

Real-World Examples from Epicforce Tech

At Epicforce Tech, we have helped clients in multiple industries apply this BAQ-to-BPM strategy to drive smarter operations.

Manufacturing Client
Implemented dynamic lead time validation based on live inventory and production queues using a BAQ. The BPM blocked job creation when production lines were overloaded.

Distribution Company
Built a BAQ to pull average order volume over the last 90 days. BPM warned the sales rep if the current order was significantly lower than usual.

Medical Supplies Vendor
Used a BAQ to verify regulatory document status. BPM prevented invoice posting if any item in the order lacked a valid FDA clearance record.

These implementations prevented errors, improved compliance, and reduced approval delays by more than 40%.

Documentation and Governance

Always document the logic and purpose of every BAQ and BPM connection. Include:

• BAQ name, logic summary, and test parameters

• BPM trigger conditions and outcomes

• Business owner of the logic

• Review date and version history

At Epicforce Tech, we maintain a shared customization log for our clients to keep logic traceable and easy to update during audits or upgrades.

Upgrade and Compatibility Considerations

While this strategy is powerful, it must be managed properly to avoid upgrade pain:

• Use Application Studio or custom layers, not base form overrides

• Test BAQ outputs in sandbox before Epicor version upgrades

• Avoid deprecated fields or hardcoded values

• Export BPMs and BAQs regularly to a version-controlled repository

We help clients build upgrade-safe logic by avoiding technical debt and using Epicors supported tools.
