If you are running with the Program Cryptographic Facility (PCF) you must define the BDT transaction prefix of “BDT” in the PCF command table before you can send any transactions to BDT through TSO or ISPF.

If BDT is going to be run from an ISPF application ID other than ISR, you must add the parameter NEWAPPL(ISR) to the command that executes the BDT command list in the other application ID.
