Our business utilizes a basic A,Q,R quality status logic. We have set our "Allocation and Issue Rules" to specify that only products in status A can be allocated. 

We continue to encounter products getting automatically allocated to sales orders in Q status. I am at a complete loss. If there's some back end parameter called "Ignore Allocation Rules" turned on, I wouldn't be surprised. 

Here is a screenshot of the offending Product Category with the relevant FEFO allocations rules applied.
