Use this setting in the dialog in Optimize when INVOICES does not correctly capture the value in the decimal places in an amount field.
If the field always has the same number of decimal places, and it is different from the number of places that INVOICES found, you should change this setting.
Note: The use of this setting is only meant to help INVOICES find the field. It is not possible to affect the output in any way using it (such as specifying how many decimals the output should have).
Example
Assume the thousands separator is a blank ( ), and the decimal separator is a comma (,).
The value on the invoice is: 200 000
INVOICES incorrectly finds 3 decimal places.
INVOICES incorrectly captures this value as: 200,000 (200 with three decimal places 000)
To fix this, you can change the Decimal places setting to 0 if the field always has no decimal places, or to 2 if the field always has either no decimal places or 2 decimal places.
