Posting link line definition file

The link line definition file defines a single field as the reference field for the posting routine and lists the names of other fields linked for the posting process. When posting is invoked, the system compares the value for the reference field in the source file with the value for the linked field in the target file. If the values are the same, the system compares the listed fields for changes and posts the new data to the target file.

The fields used for the link line definition have the same definition or use for posting as they do for find and fill with the following exceptions:

  • The source field array lists fields in the source record and the target field array lists fields in the target record.
  • You can define parameters in the Expressions field to control the posting process flow.

Note: Reference or manipulate input fields with the $File file variable. Any modifications made to this record variable are passed back to the calling application.

Important: Processing statements may modify the contents of the original record.
