The numeric correlation uses the mathematical interdependency of values to assign the correct values to the corresponding columns. The engine checks the first three columns with the numbers 0, 1 and 2 in the column list on the Column tab for correlation. The correlation follows the scheme 0 * 1 = 2. The columns must be available in the corresponding sequence.
Example for an Invoices project
Quantity * Single Price = Total Price
Example
Column order
0: Quantity
1: Single Price
2: Total Price
Note: Use this feature only when you expect the columns to correlate in most documents.
