The Enterprise Resource Planning (ERP) system is set to round invoice amounts to two decimal places, while my Ariba Procurement Solution rounds to four decimal places. This causes invoices to produce errors due to rounding discrepancies.

Contact Ariba Customer Support to request a change to the Application.Procure.ERPAmountPrecision parameter to the desired number of decimal places of precision.

The Application.Procure.ERPAmountPrecision parameter controls the precision of amount fields exported in the payment request export files. By default, the ERPAmountPrecision parameter contains:

• For SAP and Generic variants: 4 decimal places
• For PeopleSoft variants: 3 decimal places

The maximum supported precision is four (4) decimal places.

The amount in the exported, comma-separated values (CSV) files will continue to have four decimal places with trailing zeros. For example, with a precision setting of three, amount values export as 1.2340. With a the precision set to two, amount values export as 1.2300.

This parameter sets the precision of the amount fields in the payment request export files for customers whose ERP system cannot handle a decimal precision of four. Such systems may reject records when the rounding of the decimal places to the number that they support leads to a discrepancy of the sum of line-level amounts with their respective header-total amount.

Amounts round to the precision specified in the parameter. If rounding of the amount fields in the split accounting records or line-level records during payment request export results in a discrepancy with the line-level total or header-level total, respectively, the amount values of the last line level or split accounting level adjust so that the total equals the line-level or header-level total based on the specified precision.

Example: Split amounts are 3.33333, 3.33333, 3.33334, and the line-level amount is 10.00000. During export, with precision set to "3", the split amounts export as: 3.333, 3.333 and 3.334. If precision is set to "2", then, the split amount values are: 3.33, 3.33 and 3.34.

The ERPAmountPrecision parameter applies to the following columns only:

PeopleSoft:

• MERCHANDISE_AMT in PaymentDetailExport.csv
• GROSS_AMT in PaymentHeaderExport.csv
• AMOUNT in PaymentSplitAccountingExport.csv

Generic:

• Amount in PaymentDetailExport.csv
• GrossAmount in PaymentHeaderExport.csv
• Amount in PaymentSplitAccountingExport.csv

SAP:

• Precision adjustment is not required in SAP integrated sites. SAP provides its own rounding handling.
