When you run the Relationship Linker or Reference Matcher, the output is displayed in the output entities you specify. In addition to the display of data rows and matching information, you can view the actual one-to-one relationship between linked rows by specifying a Link file.
You can specify a Link file in the Advanced option in the Relationship Linker or Reference Matcher process.
When specified, after the Relationship Linker or Reference Matcher process is run, a Link file is generated and displayed in the Navigation View and Project View like a regular output entity. You can double-click the Link file in either view to display the information in the List View.
A Link file contains the following fixed attributes: from_link, to_link, match_type, and pattern_id. The from_link and to_link attributes contain the values of the attribute specified in the Linking settings. The match_type attribute shows whether the rows are Passed or Suspect ('P' for passed link, 'S' for suspect link) and pattern_id shows the match pattern.
Guidelines
- The Link file must be created when multiple Relationship Linker processes will be run using different window keys for each match. The contents of the link file are then used to resolve the links across all matches. See Multi-Matching for details.
- If you only need a Link file and do not need a transaction output file, uncheck the Generate Output Entity option in the Output Settings tab.
Example
If you want to see the link by the Sequence Number for the matched rows, the Link file would look like this:
|
from_link |
to_link |
match_type |
pattern_id |
|---|---|---|---|
|
000000001 |
000000002 |
P |
100 |
|
000000003 |
000000004 |
P |
101 |
This Link file shows that the row with the Sequence Number 00000001 links to the row with the Sequence Number 000000002, with the pattern P100. Likewise, the row with the Sequence Number 000000003 links to the row with the Sequence Number 00000004, with the pattern P101.
