Problem integrating with JDE

We are integrating with JDE 8.11 (8.97 toolset) and are using wM 6.5 and DB2 database.We use automatic notifications on the jdbc adapters.This means,on enabling we create three objects on a particular database table (F4211 Sales Order in our case)-a trigger,a buffer table and a sequence.When creating a sales order in JDE, in the last step we are facing an ASYNCHRONOUS BUSINESS FUNCTION error.The problem disappears when we disable our notifications and thereby delete the objects we created.We are befuddled by what is causing the error.
Has anyone faced this…please help!

ps : We have RTEs enabled on our instance for the same table.Could this be the problem?
