How to check if an operation is waiting due to conditions

An operation is in W (Wait) status due to condition when its condition is in U (Undefined) status.

You can list these operations by filtering on Status=W and Undefined Cond=Y in the SELECTING OPERATIONS filter panel as displayed in EQQSOPFP - Selecting operations.
