Regression in Klarna Order Handling (v6.4.2)

[mariuszsienkiewicz]

I previously reported bug #1195.

In version 6.4.2 (or probably 6.4.0, but we use currently 6.4.2), order handling has become even more problematic. While the specific bug mentioned above has been resolved, a critical feature has disappeared: partial order line cancellation.

The Issue

Previously, if a customer ordered:

• 5 units of Product A
• 6 units of Product B

If the warehouse only had 3 units of Product A in stock, staff could go into the PrestaShop order, scroll to the Mollie order block, and cancel the 2 missing units.

While bug #1195 previously prevented shipping via the PrestaShop Back Office, the order state remained correct, and the Mollie account manager could still fulfill the shipment via the Mollie Dashboard.

Current Behavior

In the current version of the module, it is only possible to cancel an entire order line (e.g., all 5 units of Product A). There is no longer an option to cancel partial quantities. This makes Klarna order management impossible for our warehouse staff.

Summary

This is a significant regression. To put it simply, we have lost essential functionality that was working in previous iterations.

Hi,

Thank you for the detailed report. We've confirmed this is a regression introduced in v6.4.0 partial order line cancellation was unintentionally removed. A fix is planned.

As a workaround, partial cancellations can still be done directly via the Mollie Dashboard.

When can we expect the update?

The suggested workaround is unfortunately not viable, as warehouse staff typically do not have access to the Mollie Dashboard due to security restrictions.

Hi,@mariuszsienkiewicz

Thank you for reaching out.

We’ve forwarded this to our development team, and it will be included in the next release. We could also provide a patched module with a fix if you like, just let us know.

We appreciate your patience in the meantime.

Hi, @mariuszsienkiewicz

Quick question: is the Order API being used to handle payments within the module?

Yes, we are using the Orders API for Klarna payments :)

Hi,

Our development team has already prepared a fix, which is currently in testing. We typically bundle all upcoming fixes into a beta release first, and that should be out next week. Would that work for you?

Hi @TLabutis,

of course, that will be enough for us. Or maybe you already have a build that seems to fix this issue, #1353, and #1352? If so, that could speed things up for us and we could get back to you with feedback faster.
