In the world of Epicor ERP, Business Activity Queries (BAQs) are the heartbeat of operational reporting and decision-making. They help teams extract, filter, and manipulate data from Epicor’s vast database to generate dashboards, SSRS reports, and real-time metrics.
But what happens when a BAQ doesn’t deliver the data you expect? If you’re constantly asking:
- “Why is my BAQ missing records?”
- “Why are my filters not working properly?”
- “Why is this data inconsistent across reports?”
You’re not alone.
This blog post unpacks the most common reasons BAQs fail to deliver accurate results, and how to refine, optimize, and troubleshoot them effectively. We’ll also explore how Epicforce Tech helps organizations clean up, fine-tune, and scale their BAQs for precise and reliable output.
Whether you’re an Epicor admin, power user, or business analyst—this guide will help you level up your BAQ skills and eliminate frustrating data issues for good.
What Is a BAQ in Epicor?
A Business Activity Query (BAQ) is a tool in Epicor ERP that allows users to create customized queries against the application database. BAQs can:
- Extract data from tables or views
- Join related tables
- Apply filters and criteria
- Display results in dashboards or reports
- Power calculated fields and KPIs
They’re incredibly powerful—but they require precision, and even a small error in setup can cause incorrect data to appear (or disappear altogether).
Common Reasons Your BAQ Is Not Delivering the Right Data
Let’s break down the most common pitfalls users encounter:
1. Incorrect Table Joins
One of the most overlooked issues in BAQs is improper join conditions. When tables aren’t linked with the correct relationship (e.g., inner vs outer join, or mismatched keys), data can be:
- Duplicated
- Excluded
- Mismatched
Fix Tip: Always confirm relationships using the Data Dictionary Viewer or Table Relationships. Understand which joins should be inner vs left outer based on business logic.
2. Missing or Misused Criteria
If your criteria (filters) aren’t specific enough—or too restrictive—you’ll either see too much or too little data.
Examples:
- Date filters not accounting for time components
- Filters using incorrect operators (e.g., “=” instead of “LIKE”)
- UserID or Plant not being passed correctly from context
Fix Tip: Always validate filter values and test criteria one by one to isolate problems.
3. Improper Use of Calculated Fields
BAQs allow you to create calculated fields, but these calculations must be SQL-compatible and logically sound.
Common issues:
- Division by zero
- Improper CASE statements
- Wrong data types being cast or concatenated
Fix Tip: Test calculated fields separately before adding them to full query logic. Use SQL CASE wisely.
4. Subqueries and Aggregate Confusion
Subqueries are powerful but tricky. If not configured correctly, they can break joins or return unintended results.
Fix Tip: Avoid nesting subqueries unnecessarily. If using aggregates like SUM or COUNT, ensure you’re grouping by the correct fields.
5. Security and Permissions
Sometimes, it’s not the query—it’s the user. Lack of access to certain tables or columns may cause data to be blank.
Fix Tip: Confirm user roles and BAQ permissions under BAQ Security Maintenance.
6. Date/Time Mismatch
When filtering by date, Epicor often stores timestamps. So filtering by = Today might miss records from earlier in the day.
Fix Tip: Use BETWEEN clauses or strip time using SQL functions when appropriate.
How to Troubleshoot and Refine BAQs – Step-by-Step
To truly refine your BAQs, follow this workflow:
Step 1: Start Simple
Begin with a single table. Check if base data looks correct before adding joins, filters, or calculated fields.
Step 2: Test Joins Incrementally
Add one table at a time, checking results as you go. Use table aliases and examine if joins affect data count or duplication.
Step 3: Validate Criteria
Manually run the BAQ without filters. Then, apply each filter individually to confirm they work as intended.
Step 4: Review Calculated Fields
Look for logic errors, data type mismatches, and syntax issues. Use Epicor’s expression editor to catch common problems.
Step 5: Profile the Performance
Use Query Execution Trace to understand which parts of your BAQ are slow. Indexing or optimizing SQL may be needed for large datasets.
Step 6: Compare to Transaction Logs
If data looks wrong, verify against transactional logs or source records in the system (e.g., Invoice Tracker, Job Tracker).
Advanced Tips for Power Users
Use Union and Common Table Expressions (CTEs)
Epicor BAQs support union and CTE-like behavior to combine complex datasets.
Link BAQs to Dashboards and Trackers
Embed your refined BAQs in real-time dashboards to detect business anomalies quickly.
Leverage BAQ Export Definitions
Push data externally using BAQ Export Definitions—perfect for automation or integration tasks.
Pair BAQs with BPMs
Trigger Business Process Management (BPM) workflows based on BAQ results—for example, send an alert if inventory drops below a threshold.

Real-World Use Case: BAQ Fix That Unlocked $50K in Savings
A mid-sized manufacturing company came to us with inaccurate inventory valuation reports. Their BAQ included:
- 7 table joins
- Two calculated fields
- Poorly applied filters
Our team:
- Simplified the query by restructuring joins
- Rewrote calculated fields using SQL CASE logic
- Applied accurate UOM conversion filters
- Validated results against physical inventory logs
The result? A real-time valuation dashboard that helped uncover $50,000 in overstocked materials, which they liquidated strategically.
