Why does Fishbowl say "Cannot configure custom configurations on a Historical Order."?

You're trying to set up custom configurations on an order that Fishbowl considers historical or completed. Fishbowl typically marks orders as historical once they've been fulfilled or processed, and doesn't allow modifications to those records to maintain audit integrity.

Fishbowl: Cannot configure historical orders

What it means

You attempted to configure custom settings on a Sales Order that Fishbowl has classified as historical—usually because the order is completed, shipped, or otherwise archived. Fishbowl protects historical orders from modification to maintain audit integrity and prevent accidental changes to past transactions.

What to check

Order status: Verify whether this order is marked complete, fulfilled, shipped, or archived. If it is, you may not be able to customize it.
Timing: Typically you configure custom settings on active or draft orders before they’re finalized.
New vs. past: Check whether you meant to configure a current order instead of a historical one, or whether this configuration should have been done earlier in the order’s lifecycle.
