Before creating new transaction ID objects, you may want to download existing transaction ID objects for the current region, to get the most recent information from the mainframe host. Use these steps:
If you click OK, CICS BAC connects to the mainframe, downloads the objects, and adds the downloaded transaction ID objects to the TransIDs folder. If instead you click the Browse host button, CICS BAC connects to the mainframe and returns a list of transaction object names from the CICS region's control file that match the name provided. You may then select a transaction ID to be downloaded from the control file. If you haven't already specified a host user ID and password, you will be asked to enter your user ID and password to complete the connection.
