The driver has various features to help you manipulate data:
Publisher Channel event status processing
The Publisher channel treats each object in an IDoc as a unique event. The status of each event determines the appropriate IDoc filename extension. For example, all events with a Warning status are placed in a file with the .warn extension.
Publisher Channel Only configuration options
The Publisher Channel Only option in the driver’s parameters enables connectivity to a SAP host for read and query operations. The driver vetoes any subscription modifications sent to the SAP system if this option is selected.
Publisher Connection option
This option informs the driver whether or not Publisher channel connectivity to the SAP system is desired.
Publish History Items
This option specifies whether the driver returns data values that no longer have a current validity period.
Future-dated IDoc processing
Future-dated IDoc processing implements a stale event data check. When future-dated events are processed, the driver attempts to confirm the validity period of the event. If no matching validity period is found for the event data, the IDoc data is considered stale and is not applied. Validity checking can only be accomplished if SAP system connectivity is established through configuring the driver’s authentication parameters. Publisher Channel Only drivers without connectivity process all future-dated events at the indicated date.
Character set encoding is used to parse data from IDocs.
The driver allows you to specify which character set encoding is used to parse data from IDocs. If nothing is specified, the driver uses the platform default encoding. If you incorrectly specify a character set, the driver initialization fails. You specify this encoding option in the driver configuration parameters.
Subscriber channel events are applied only to the current instance of SAP Infotype data. Future-dated instances are not affected.
The Subscriber channel offers several modes for synchronizing Communication and Internal Data infotypes. All other updates are made as changes to the current valid data.
The JCOTEST utility validates that all JCO connectivity and authentication parameters are configured correctly.
