GEM is based on Internet Explorer and works only in the PCC which is set on the agent’s computer the in TCP/IP in Control Panel as default, otherwise you can receive the error response mentioned above:
If you need to exchange/reissue a ticket in another PCC, you need to:
- change the settings of the default PCC on your computer, or
- you can prepare the whole exchange/reissue in the default PCC, store Filed Fare and Exchange mask in the PNR, then open this PNR in a different PCC and issue a new ticket using only the >TKP< entry.
