FB02 Simulation mode

Hi folks,

I am trying to modify a set of documents from a file, but the requirement exacts a simulation or 'test run' mode for the process befor going into 'real' mode. The modification is made using a bdc 'call transaction' to the FB02. This transaction doesn't have the 'Simulate' or 'Check' options like the FB01. The question is:

Is there a way to perform a preliminary check in this transaction? or is there a FM to perform the same operation which includes this functionality?

Thanks a lot,

Sergio.
