If your workflow involves setting some constraints in the OR through an agent of different data query type using data type association before it is sent for a BulkPlan,this scenario is very much possible.We have also had such an instance where our Bulkplan required more than an iteration to plan our ORs..
The workaround we did was,we moved all the related updates into an OrderRelease agent which was previuosly done by an agent of a different data query type using data type association and we were able to overcome the cache issue to enable our BulkPlan plan the ORs in the first go itself..
Please let me know it this relates to you..
