CONNECTION_ATTEMPTS
Defines the maximum number of times to attempt establishing a connection to an adapter before returning an error. The default value is 1. This parameter is optional.
If multiple INSTANCE parameter values are specified, the value of CONNECTION_ATTEMPTS defines the maximum number of times to iterate through the list of adapter instances.
CONNECTION_ATTEMPT_INTERVAL
Defines the amount of time, in seconds, to delay between connection attempts. The default value is 60 seconds. This parameter is optional.
If multiple INSTANCE parameter values are specified, the value of CONNECTION_ATTEMPT_INTERVAL defines the number of seconds to wait between the attempts to iterate through the entire list of adapter instances.
DBUSER
Specifies the username to use when authenticating to the SAP system. If this parameter is specified in this webject, the webject value takes precedence over any value specified in the credentials mapping settings or in the adapter LDAP entry. If this parameter is not specified here, it must be specified in the credentials mapping settings or in the adapter LDAP entry. For more information about credentials mapping, see the section
Credentials Mapping. This parameter is optional.
GROUP_OUT
Specifies the name of the group returned by the webject. The webject stores the session ID in this group, which in turn would be accessed by the subsequently executed webjects that participate in the same transaction. This parameter is optional.
INSTANCE
Specifies the name of the adapter that executes the webject. Adapter names are defined when the adapter is configured for use in your Info*Engine environment. This parameter is required.
PASSWD
Specifies the password to use when authenticating to the SAP system. If this parameter is specified in this webject, the webject value takes precedence over any value specified in the credentials mapping settings or in the adapter LDAP entry. If this parameter is not specified here, it must be specified in the credentials mapping settings or in the adapter LDAP entry. For more information about credentials mapping, see the section
Credentials Mapping. This parameter is optional.
SESSION_ID
This parameter is optional. If the user does not provide this parameter, a session ID will be generated internally and stored in the output group. However, if the user does provide this parameter, the specified value will simply get stored in the output group.
