Thanks for the fast answers.
My situation is as follow, I need to Create Journal Entry automatically so I am using MDR (Mass Data Run) but the MDR only can execute BO-Action and the Journal Entry is only created in Before-Save, so how can i do in this situation? I thought with the MDR execute a BO-Action and then call the Before-Save for create the Journal Entry.
Note: My BO don't have screens.

Adriano.
