Procedimiento para Administradoras de Sistemas

Communication with the external reservation system takes place across an
external gateway. Use Transaction SM59 to test the RFC destination
<ZH>&v1&</><ZH></> (under TCP/IP Connections). This call was not
successful in the application program and resulted in the error
<ZH><ZH>&V2&</></><ZH><ZH> &V3& </></>
The connection will only work in the application program once the test
using SM59 has been completed successfully without errors. In
particular, the program must be registered with the gateway.
In certain situations (particularly in a test environment), it may be
necessary to communicate with the current or another reservation system
using a different RFC destination. To do this, you must make settings in
Customizing under Financial Accounting -> Travel Management -> Travel
Planning -> Master Data -> Technical Control Parameters for Travel
Planning. For further information, see the documentation for that
activity and the documentation for Technical and Organizational
Prerequisites.
