Supplier Invoices - "Duplicate entry '1' for key 2

Using my Dolibarr
1

Hello Dolibarr world.

I am having an issue trying to process supplier invoices in V3.9 which I cannot resolve. Can anyone please offer some suggestion how I can overcome this problem?

When I try to validate a supplier invoice I get a red error message saying “Duplicate Entry ‘1’ for key 2”.

I have changed nothing about my setup as far as I can remember. This situation is now desperate. If I can’t find a solution very soon I will have to find another ERP and change my whole system over. This is obviously going to take allot of effort which I would rather avoid.

I hope to hear back something soon. Any assistance will be greatly appreciated.

Thanks in advance for your help.
