Order Release Not Found Error in FWB

Hello there!

When we do order allocations in FWB, we occasionally get the following error:

**Business Layer Exception**

Order Release not found.

Exception caught in: Epicor.ServiceModel

**Error Detail**

============

**Description:** Order Release not found.

**Program:** Erp.Services.BO.OrderAlloc.dll

**Method:** unallocateOrder

**Line Number:** 12616

**Column Number:** 25

**Table:** OrderAlloc

**Client Stack Trace**

==================

at Epicor.ServiceModel.Channels.ImplBase`1.ShouldRethrowNonRetryableException(Exception ex, DataSet[] dataSets)

at Erp.Proxy.BO.OrderAllocImpl.AutoAllocation(OrderAllocDataSet ds, String cIPWhseList, String cWhseType, String& cMessageText, Boolean& lReleased)

at Erp.Adapters.OrderAllocAdapter.AutoAllocation(String cIPWhseList, String cWhseType, String& cMessageText, Boolean& lReleased)

Unfortunatly this message appears in a bulk of other orders and does not specifically indicate which order release has the issue. Does anyone have any ideas on why this may happen?
