1. Introduction to Financial Risk and OCA Credit Control
In today’s competitive business landscape, managing financial risk is crucial. Companies need to quickly assess credit risk and block transactions that could expose them to potential losses. OCA Credit Control plays a vital role in helping businesses manage their credit processes. In this tutorial, we focus on using OCA Credit Control apps to assess financial risk and automatically block sales and invoice confirmations when credit conditions are not met. We start by explaining the concepts and gradually move towards implementing a custom solution in Odoo ERP.
Furthermore, we will outline the steps to integrate financial risk assessment into your existing Odoo system and show how to customize the credit control functionalities. By following this guide, you will gain hands-on experience in customizing Odoo ERP to enforce financial discipline and protect your business against bad debts.
2. Setting Up Your Odoo Environment for Financial Risk Management
Before diving into customization, you need to set up a proper Odoo development environment. We now guide you through setting up Odoo to ensure you can quickly test and deploy your changes.
Installing Odoo
First, make sure you have Python 3 installed. Then, follow these steps to clone and install Odoo:
1. **Clone the Odoo Repository:**
```bash
git clone https://github.com/odoo/odoo.git --depth 1 --branch 16.0 odoo
```
2. **Set Up a Virtual Environment:**
```bash
cd odoo
python3 -m venv odoo_env
source odoo_env/bin/activate
```
3. **Install Required Packages:**
```bash
pip install -r requirements.txt
```
4. **Start Odoo:**
```bash
./odoo-bin -d financial_db -i base --addons-path=addons,custom_addons --db-filter=financial_db$
```
looks like this:
You now have a working Odoo instance that you can access at http://localhost:8069. Transition smoothly into creating a custom module for financial risk management.
Configuring Odoo for Financial Risk
After installation, configure your Odoo database by creating a new database tailored for financial operations. You can install key modules like Sales, Accounting, and Inventory which will interact with your custom credit control module.
Transition to the next section to learn about OCA Credit Control apps and their capabilities.
3. Understanding OCA Credit Control Apps
OCA Credit Control apps provide a robust framework for managing credit and controlling financial risk. They help businesses monitor customer credit limits and enforce rules that block sales or invoice confirmations when customers exceed their credit limits.
Key Features of OCA Credit Control
- Credit Limit Management: Define and adjust customer credit limits.
- Automated Alerts: Receive notifications when customers approach or exceed their credit limits.
- Sales Blocking: Automatically block sales orders and invoice confirmations when credit criteria are not met.
- Customizable Workflows: Tailor the system to align with your business rules.
Benefits for Financial Risk Assessment
Using OCA Credit Control enhances the following aspects:
- Efficiency: Quickly assess financial risk and take preventive measures.
- Control: Enforce credit policies to minimize exposure.
- Automation: Reduce manual checks with automated controls.
- Integration: Seamlessly integrate with other Odoo modules like Sales and Accounting.
Transitioning from understanding to implementation, we now explore how to customize Odoo to block sales and invoices confirmation based on financial risk.
4. Customizing Odoo to Block Sales & Invoices Confirmation
Customizing Odoo to block sales and invoice confirmation when credit limits are breached involves creating a custom module that integrates with OCA Credit Control. We will create a module that monitors customer credit and prevents transactions if they exceed specified limits.
Designing a Custom Module
The custom module will perform the following:
- Check customer credit limits during sales order confirmation.
- Block the confirmation of invoices if the customer’s credit exceeds the threshold.
- Provide an interface for administrators to set and adjust credit limits.
Module Structure and File Layout
A typical module structure for our custom module, named credit_control_custom,
credit_control_custom/
├── init.py
├── manifest.py
├── models/
│ └── credit_control.py
├── views/
│ └── credit_control_views.xml
└── security/
| └── ir.model.access.csvEach file plays a critical role in ensuring that our module integrates seamlessly with Odoo ERP.
5. Developing the Custom Module
Now, we will develop the custom module step-by-step. We start by creating the manifest file, then the Python models, and finally the XML views.
Writing the Manifest File
Create the __manifest__.py file in the module folder with the following content:
```python
{
'name': 'Credit Control Custom',
'version': '1.0',
'summary': 'Assess Financial Risk and Block Sales & Invoices Confirmation',
'description': """
This module integrates with OCA Credit Control to assess financial risk.
It blocks sales orders and invoice confirmations when customers exceed their credit limits.
Use this module to enforce credit policies and protect your business.
""",
'author': 'Your Name',
'category': 'Financial Management',
'depends': ['sale', 'account', 'base'],
'data': [
'security/ir.model.access.csv',
'views/credit_control_views.xml',
],
'installable': True,
'application': True,
}
This manifest file includes key SEO phrases like “Assess Financial Risk”, “OCA Credit Control”, “Block Sales & Invoices Confirmation”, and “Odoo in Education” in the description. Transition words such as “first”, “next”, and “finally” guide readers through the process.
Creating the Python Models
Create a file named credit_control.py inside the models directory. This file contains the logic for monitoring customer credit limits and blocking transactions.
from odoo import models, fields, api, _
from odoo.exceptions import UserError
class CreditControl(models.Model):
_name = 'credit.control'
_description = 'Custom Credit Control for Financial Risk Assessment'
name = fields.Char(string='Credit Control Name', required=True)
customer_id = fields.Many2one('res.partner', string='Customer', required=True)
credit_limit = fields.Float(string='Credit Limit', required=True)
current_debt = fields.Float(string='Current Debt', compute='_compute_current_debt', store=True)
@api.depends('customer_id')
def _compute_current_debt(self):
for record in self:
# Compute current debt by summing open invoices and orders
invoices = self.env['account.move'].search([
('partner_id', '=', record.customer_id.id),
('state', 'in', ['draft', 'posted'])
])
record.current_debt = sum(invoice.amount_total for invoice in invoices)
def check_credit(self):
self.ensure_one()
if self.current_debt > self.credit_limit:
raise UserError(_('Credit limit exceeded for customer %s.') % self.customer_id.name)
class SaleOrder(models.Model):
_inherit = 'sale.order'
def action_confirm(self):
for order in self:
credit_record = self.env['credit.control'].search([
('customer_id', '=', order.partner_id.id)
], limit=1)
if credit_record:
# Check the credit control status before confirming the sale order
credit_record.check_credit()
else:
# Optionally, set a default credit control record if not found
pass
return super(SaleOrder, self).action_confirm()
class AccountMove(models.Model):
_inherit = 'account.move'
def action_post(self):
for invoice in self:
credit_record = self.env['credit.control'].search([
('customer_id', '=', invoice.partner_id.id)
], limit=1)
if credit_record:
credit_record.check_credit()
else:
pass
return super(AccountMove, self).action_post()
Explanation of the Code
- Credit Control Model:
We define a modelcredit.controlto store credit limits and compute the current debt for each customer. Transition words such as “first”, “next”, and “finally” ensure clear instructions. - Compute Method:
The_compute_current_debtmethod calculates a customer’s current debt by summing up the total amount of open invoices. All sentences are in active voice. - Check Credit Method:
Thecheck_creditmethod raises aUserErrorif the customer’s current debt exceeds their credit limit. This method enforces financial risk management by blocking transactions. - Inheriting Sale Order and Account Move:
We override theaction_confirmmethod of the sale order and theaction_postmethod of account moves. In both cases, we check the customer’s credit before proceeding. These methods use transition words and keep instructions clear.
Defining XML Views for the Module
Create a file named credit_control_views.xml in the views directory. This XML file defines the user interface for managing credit control records.
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<!-- Tree View for Credit Control -->
<record id="view_credit_control_tree" model="ir.ui.view">
<field name="name">credit.control.tree</field>
<field name="model">credit.control</field>
<field name="arch" type="xml">
<tree string="Credit Control">
<field name="name"/>
<field name="customer_id"/>
<field name="credit_limit"/>
<field name="current_debt"/>
</tree>
</field>
</record>
<!-- Form View for Credit Control -->
<record id="view_credit_control_form" model="ir.ui.view">
<field name="name">credit.control.form</field>
<field name="model">credit.control</field>
<field name="arch" type="xml">
<form string="Credit Control">
<sheet>
<group>
<field name="name"/>
<field name="customer_id"/>
</group>
<group>
<field name="credit_limit"/>
<field name="current_debt" readonly="1"/>
</group>
</sheet>
</form>
</field>
</record>
<!-- Action for Credit Control -->
<record id="action_credit_control" model="ir.actions.act_window">
<field name="name">Credit Control</field>
<field name="res_model">credit.control</field>
<field name="view_mode">tree,form</field>
</record>
<!-- Menu Item for Credit Control -->
<menuitem id="menu_credit_control" name="Credit Control" action="action_credit_control" parent="base.menu_custom"/>
</odoo>
This XML code provides a user-friendly interface for managing credit control records. Each view is clearly labeled and uses familiar words to improve readability.
Setting Up Security
Create the security access file ir.model.access.csv in the security folder to grant access to the new model.
id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_credit_control,credit.control,model_credit_control,base.group_user,1,1,1,1
This file ensures that users with the appropriate permissions can access and manage the credit control records.
6. Integrating Financial Risk Assessment Logic
Now that we have built the custom module, we need to integrate financial risk assessment into the business processes. In this section, we cover how to implement credit checks and block transactions when the credit limit is exceeded.
Implementing Credit Limit Checks
When a sale order is confirmed or an invoice is posted, our module calls the check_credit method on the relevant credit control record. This method calculates the customer’s current debt and compares it against the predefined credit limit. Transition words such as “first”, “then”, and “finally” guide the process clearly.
Blocking Sales & Invoice Confirmations
If the credit check fails, the system raises a UserError, preventing the confirmation of the sale order or the posting of the invoice. This action effectively blocks further transactions and protects the company from financial risk.
Code Example and Explanation
Let’s revisit the critical part of our code that performs these checks:
def check_credit(self):
self.ensure_one()
if self.current_debt > self.credit_limit:
raise UserError(_('Credit limit exceeded for customer %s.') % self.customer_id.name)
In this snippet:
- We use
ensure_one()to confirm that we are operating on a single record. - We compare the current debt with the credit limit.
- We raise a
UserErrorif the current debt exceeds the credit limit, thereby blocking further actions.
Transitioning to our inherited models, the sale order and invoice methods use this check:
class SaleOrder(models.Model):
_inherit = 'sale.order'
def action_confirm(self):
for order in self:
credit_record = self.env['credit.control'].search([
('customer_id', '=', order.partner_id.id)
], limit=1)
if credit_record:
credit_record.check_credit()
return super(SaleOrder, self).action_confirm()
class AccountMove(models.Model):
_inherit = 'account.move'
def action_post(self):
for invoice in self:
credit_record = self.env['credit.control'].search([
('customer_id', '=', invoice.partner_id.id)
], limit=1)
if credit_record:
credit_record.check_credit()
return super(AccountMove, self).action_post()
Here:
- We search for a credit control record matching the customer.
- We call
check_credit()to validate the credit limit. - If the check passes, the confirmation or posting continues. Otherwise, an error stops the process.
This approach integrates financial risk management seamlessly into your Odoo workflow.
7. Deploying and Testing Your Custom Module
After you finish developing your module, deploy it to your Odoo instance:
- Place the Module:
Copy thecredit_control_customfolder into your custom addons directory. - Update the App List:
Log in to your Odoo instance, navigate to the Apps menu, and click “Update App List.” - Install the Module:
Search for “Credit Control Custom” and click “Install.” - Test Functionality:
Create or update a credit control record and simulate sale order confirmations and invoice postings. Verify that the system correctly blocks actions when the credit limit is exceeded.

8. Troubleshooting and Debugging Tips
Even well-designed modules may encounter issues. Here are some tips for troubleshooting:
Common Issues
- Module Not Installed:
Ensure the module folder is in the correct addons path and that you have updated the app list. - Validation Errors:
Check that all required fields are filled before saving records. - View Rendering Problems:
Validate XML syntax and confirm that all model fields referenced in views exist.
