You can use any of the Interactive Data Capture indexing features to map the appropriate Keyword Type name from the standard Keyword panel to the corresponding column header in the Line Item Extraction Verification panel. For instance, if a column in the Line Item Extraction Verification panel displays values for the Item Description Keyword Type but has a generically named header (e.g., Column 2), using Interactive Data Capture to index one of these values in the Item Description Keyword Type field will rename the generic column header to Item Description.
