EDF and remote transactions

You cannot use EDF in dual-screen mode if the transaction that is being tested, or the terminal that invokes it, is owned by another CICS® region.

If a remote transaction ends abnormally while under EDF using a CRTE routing session, EDF displays the abnormal task termination screen, followed by message DFHAC2206 for the user transaction. The CRTE session is not affected by the user task abend. Also, if you opted to continue with EDF after the abend, your terminal remains in EDF mode within the CRTE routing session.

There is a difference in execution as well. For remote transactions, EDF purges its memory of your session at the termination of each transaction, whether EDF is to be continued or not. This means that any options you have set, and any saved screens, are lost between the individual tasks in a pseudoconversational sequence.
