background job using event trigger

Hi all,

i wants to update batch when i release and save the process order.i am using badi workorder_update ,in that i am not able to use the bapi_batch_change directly because it has commit work and it is giving me dump if i use the bapi so now i had written bdc in that ,but this is also not working as the batch tables are locked....

now i am planning to write report program and schedule it as background and will trigger based on event whihc i do it in the badi again.now my question is the user will be releasing the order so when i want to trigger the program in bg job i have to pass the materila and plant using parameter ids will this work as bg job will have wf-batch as user...please suggest..
