How to find if a sales order was released without any pick release rule

Hello We usually release our sales orders manually from the Release Sales Orders form by selecting the Release rule name and Sales order number Shipping --> Release Sales Orders --> Release Sales Orders (WSHFRREL.fmx) --> Concurrent We have plans to make the Based on Rule field (lov for Release rules) as mandatory, however sometimes the users are missing to select the release rule. Is there any sql or any other way to find out if sales orders released from the form were released without selecting the list of values. Thanks Joe
