Dear Team,

Thank you for explaining your current situation in detail.

Based on your description, the restriction you are encountering in 2026—where only an Administrator can modify the purchase order date—is expected behavior in Odoo when user access rights or system rules have been tightened. This can happen due to configuration changes, database upgrades, or security rules being enforced over time, even if no active administration has taken place.

The good news is that this issue is fully solvable without disrupting your current usage of Odoo Community, and you can safely continue using the same version until you decide on an upgrade or migration path.

Here are the practical options available:

1. Restore or Reassign Administrator Access

   If the original administrator account still exists, we can help regain access and adjust the required permissions. If not, a new administrator can be created directly at the database level to restore full control of the system.

2. Adjust User Permissions for Purchase Orders

   Once administrator access is available, we can specifically allow authorized users to modify document dates for purchase orders, without opening unnecessary access to other modules.

3. Stabilize the Current Community Setup

   Since you are only using Odoo for purchase orders, goods receipt, and reporting, we can streamline and secure the system so it continues to function reliably in the short and medium term.

4. Prepare for Future Upgrade or Migration

   In parallel, we can review and propose options for:

   • Upgrading to a newer Odoo Community version

   • Migrating to Odoo Enterprise

   • Planning a clean transition that preserves your historical purchase and reporting data

Our recommendation is to first restore administrator control and fix the immediate issue, so your daily operations are not impacted, and then evaluate long-term improvement options at your convenience.

We would be happy to assist you with this and discuss the most suitable approach based on your priorities.

We look forward to hearing from you and supporting you further.

Kind regards,
Zehntech Technologies
