Error message returning an inventory item applied against a project

Verify the Warehouse Configuration:

Go to Inventory → Warehouses and check if warehouse 236 exists.
If it does not exist, verify which warehouse is assigned to the stock item in PO Receipt Return.
Check the Project-Specific Inventory Location:

When items are received in a project, they are often allocated to a specific location tied to the project.
Try reviewing INTran or Project Transactions to check where the stock item was initially received.
Review PO Receipt and Issue Transactions:

If the item was issued to a project, reversing it via a PO Receipt Return may not be the right approach.
Instead, you might need to manually adjust the inventory using an Inventory Adjustment (IN Adjustment).
Use Inventory Adjustment (Alternative Solution):

Navigate to Inventory → Inventory Transactions → Adjustments.
Create an Adjustment Entry to:
Remove the item from the project location.
Add it back to the correct inventory warehouse.
Ensure Inventory Availability:

If Acumatica believes the item is not available for return, try running Inventory Recalculation under System Processes.
Check PO Receipt Return Settings:

Make sure the PO Receipt Return is correctly referencing the original receipt document.
Ensure that the Return Type is properly selected to avoid conflicts with the project allocation.
Check the Inventory Allocation Setup:

Go to Inventory Preferences and check the Allocation Settings.
If the item is allocated to the project, you may need to unallocate it before performing the return.
