Export Manage Receivable Activities

Is there a way to export the results in Manage Receivable Activities setup & maintenance screen? Or is there a back end table I can create a data model and report off of?

Would it be the AR_RECEIVABLES_TRX_ALL table? Would this capture all that exist or only all that have been used since it sounds like it's transaction based rather than config/setup based. This table doesn't seem to provide the GL. It only seems to provide GL_ACCOUNT_SOURCE which simply references ACTIVITY_GL_ACCOUNT. I don't see an ID that I can take to join another table to get the full GL string.
