Common Errors and Solutions

Many users report similar ERPNext manufacturing module issues. Most are related to data entries, missing configurations, or system overload. The good news is that most problems have quick fixes.

Below are the most frequent ERPNext errors in manufacturing along with easy ways to solve them.

1. Stock Balance Issues

Problem

Your stock levels don’t match the system reports. You expect items in inventory, but they show zero.

Causes

1. Unrecorded material transfers
2. Wrong warehouse selection
3. Missing stock entries after production

Fix

1. Use Stock Ledger Report to trace movements
2. Perform a stock reconciliation to adjust quantities
3. Always update warehouse data after every transaction

Tip: Do a monthly audit using the Stock Reconciliation tool to reduce inventory discrepancies.

2. Production Order Not Getting Created

Problem

Sometimes, you're unable to create a production order, which blocks your entire manufacturing process.

Causes

1. No or incorrect Bill of Materials (BOM) attached to the item
2. Not enough raw materials in stock
3. Production planning settings are wrong or incomplete

Fix

1. Validate the BOM to make sure it’s linked to the right item and version
2. Check inventory levels for all required raw materials
3. Review Manufacturing settings under the Setup module to confirm planning dates and default warehouses

Checklist Before Creating Production Order:

Quote:

"Most failed production orders trace back to missing or outdated BOMs. Always keep BOMs clean and current."

3. Work Order Not Closing

Problem

You’ve finished all production activities, but the work order stays open. This can delay other jobs and create reporting issues.

Causes

1. Some operations are not marked as completed
2. Stock entries are still in draft or missing
3. Manual oversight by the production team

Fix

1. Make sure all operations in the work order are marked "Completed"
2. Submit all linked stock entries, especially the ones related to finished goods
3. Use the Work Order Completion tool to verify and manually close if everything checks out

Pro Tip: Use a dashboard or automated reminder to track pending work orders daily.

4. Error in Material Request

Problem

Users encounter errors while creating or submitting a material request in ERPNext. This slows down procurement and affects the entire manufacturing workflow.

Causes

1. Items are not properly configured or are out of stock
2. User permissions are too limited
3. Filters in the list view are blocking access to item data

Fix

1. Check that all items in the request are active and have enough stock
2. Use the Stock Ledger Report to verify real-time inventory
3. Update Role settings in Permission Manager to allow access
4. Remove or reset list view filters in the Material Request screen

Quick Tips to Avoid This Error:

1. Audit user roles monthly
2. Keep stock levels accurate through regular stock reconciliation
3. Train staff on using filters and request forms correctly

5. Inaccurate Costing

Problem

Final product costs don’t reflect true production expenses, leading to wrong pricing, budgeting errors, and profit miscalculations in your manufacturing ERP reports.

Causes

1. Wrong costing method selected (e.g., FIFO, LIFO, or Moving Average)
2. Missing entries for labor, machine time, or overhead in the Bill of Materials (BOM)
3. Outdated item prices used in production calculations

Fix

1. Choose the right costing method in the Item Master settings
2. Regularly update the BOM with accurate costs for materials, labor, and energy
3. Record all indirect costs like subcontracting, transportation, and machine wear-and-tear

Pro Tip: Use ERPNext’s production analytics to monitor differences between estimated and actual costs over time.

6. User Permission Issues

Problem

Some users can’t access parts of the ERPNext manufacturing module. They may be blocked from editing documents, submitting forms, or even viewing certain reports.

Causes

1. Incorrect or missing role settings in the user profile
2. Limited access to specific Doctypes or linked documents
3. Child tables or modules restricted due to custom user permissions

Fix

1. Go to Role Permission Manager and check access for affected users
2. Add or adjust the necessary roles like “Stock User,” “Production User,” or “Material Manager”
3. Verify that child tables (e.g., operations, material details) are accessible under the same role
4. Run regular audits on ERP user roles to ensure compliance and fix permission errors

Quick Tip: Use the “Show Permissions” button in ERPNext to troubleshoot access issues in real-time.

7. System Performance Issues

Problem

Sometimes, ERPNext becomes slow, especially when multiple users are active. Pages take too long to load, or tasks fail to complete. This affects manufacturing operations, causing frustration and delays.

Causes

1. Insufficient server resources (RAM, CPU)
2. Poor database performance due to large unoptimized queries
3. Old software version or too many background jobs
4. Cache overload, especially in cloud-based ERP setups

Fix

1. Upgrade your server to match your user load
2. Optimize MySQL queries and clean up logs
3. Use ERPNext’s System Monitor to kill stuck jobs
4. Regularly update to the latest stable ERPNext version
5. Clear cache and restart services during off-hours
