A Line Item Extraction Field Zone allows you to extract multiple Keyword Values from a single zone when the values to be extracted are arranged in line item format using rows and columns. Values in each column of the table are assigned to the same Keyword Type.
Line Item Extraction Field Zones are intended to be used with Multi-Instance Keyword Type Groups in order to capture line item data while maintaining the Keyword Values' relationship to one another.
Keyword Values can also be extracted from line-item-formatted data into a Multiple Instance Keyword Type Group using multiple Text Data Field Zones (one for each column of data) set to use the Table style Data Application option.
Line Item Extraction Zones have two modes:
-
Automatic Table Decomposition. The OCR engine attempts to automatically detect the location of individual table columns within the Data Field Zone.
-
Manual Table Decomposition. Individual table columns are manually defined when configuring the Data Field Zone.
Both Line Item Extraction modes are configured using the options on the Line Item Extraction tab of the Data Field Zone dialog box. Once the table decomposition mode-specific options are set, you are able to set other, non-mode-specific configuration options.
