Form Extractor Input File Size Mismatch

Post mapping the fields in the input Invoice PDF using Form Extractor of Document Understanding , why are fields not being captured directly?

Root Cause: Smaller tabular data was included in the Form Extractor template.

Resolution: The size mismatch happens when supplied with a specific sample of tabular data when creating the template, but when running the process, a sample is input with larger tabular data.
In this case, not all the fields of the input document will be captured.

To avoid this behavior, make sure to include in the Form Extractor template the document with the larger tabular data.
