Bug description

After migrating GLPI from 9.5 (bare metal) to 11, the Credit plugin partially works: credit quantities display correctly in entities and related views. However, it’s not possible to apply or consume credit when creating a new ticket (or task). The “maximum consumable quantity” remains at 0 regardless of the selected credit, including unlimited credits.

​

Steps to reproduce:

Complete migration from GLPI 9.5 (bare metal) to 11(docker with no apparent data loss).

​

Update or reinstall the Credit plugin from the Marketplace (version currently in use: 1.15).

​

Go to Administration > Entities > [Entity] > Credit and verify credit types and sold/remaining quantities are correct (including unlimited).

​

Create a new ticket via Assistance > Tickets > New (or from a task/project).

​

In the ticket form, select a credit type (including unlimited) in the Credit plugin section.

Submit the ticket: consumable quantity remains 0 and no debit is applied. The ticket is created without associated charging.

​

What was expected:

To be able to apply and consume credits on new tickets as before the migration, including for unlimited credits.

​

What actually happens:

Credit quantities are visible and correct at entity level, but charging on ticket creation is blocked; the consumable quantity is fixed at 0 even with valid/unlimited credits.

​

Additional checks performed:

Verified default options at entity level to associate credit types to actions such as “New ticket”, “Follow-up”, or “Solution”.

​

Enabled “Allow overconsumption” for unlimited credits and ensured non-zero sold quantity where applicable.

​

Confirmed profiles have the necessary permissions for the Credit plugin.

​

Reviewed GLPI logs (files/_log and php-error.log); no obvious SQL/PHP errors found related to Credit consumption step. Can provide log excerpts if helpful.

​

Issue reproduces consistently on fresh tickets, even with unlimited credits configured.

Hi @delta-whiplash,

Could you please add some screenshots highlighting the fields that should be filled in?

When creating the ticket, it isn’t possible to specify the number of credits to be consumed. You can only define the default credit for this ticket, in order to override the entity’s default value.
By default, the entity’s value is used.

We are in the same entity

We just upgraded the GLPI version no more changes have been done

@stonebuzz
Do you have any solution
We've found a workaround by editing the quantity of credit consumed after consumed 0 credit but it's still painfull and we don't know if we are over consuming credit because the max consumption limit is not checked when we do this operation

[stonebuzz]

Actually, I don’t think I fully understand your issue.

Could you clarify what values are present in the entity (as defined in the credit definition)?

Also, what should I be seeing in the tickets—specifically in the field or in the tooltip—where the problem occurs?

Hello,

I have the exactly same issue. Here is my version of GLPI

Here is the quantity of credit available of one entity

But, when i want to close a ticket with solution for example, i can't spend any credit

[delta-whiplash]

@stonebuzz
Me and @Agadou have the exact same issue
It's really blocking us this days and we need it to do the accounting
Do you have any ideas for a solution to this problem?

Hello !
I've the issue.

I also noticed that when I try to add the amount of credit used directly to a receipt (Credit tab), I can't specify a quantity.

• If I enter a value, I get the message "Quantity used must be 0".
• If I let the value to "0", I get this message: "Credit voucher quantity must be greater than 0."

So basicaly, it must be 0 AND >0

Hi everyone, could you please test this pull request? → #208

Hi,

Thank you for the update !

The changes made have not completely solved my problem.

• Add a credit amount to a solution: OK

• Add a credit amount to a follow-up: OK

• Add a credit amount to a task: OK

• Add a credit amount directly from the “credit” tab: NOT OK

Hi,

Sorry but i'm new to this. How i download the update please ? GLPI is on docker and i intalled plugin with marketplace

[stonebuzz]

@Agadou

You will need to wait for a release, or alternatively, connect via SSH to the Docker image to apply the changes manually.
