On sites using ERS and approvable determination rules or account determination rules, the determination rules were not applied to ERS invoices. As a result, fields that were supposed to get their default values based on the determination rules had incorrect default values.

Now, you can set a parameter to have determination rules applied to ERS invoices.

Action required

To apply account or approvable determination rules to ERS invoices, set the site parameter Application.Invoicing.ApplyApprovableDeterminationRulesToERS to Yes. Members of the Customer Administration group can perform this task.

1. From the dashboard, choose Manage > Core Administration.
2. Choose Customization Manager > Parameters.
3. Find the parameter Application.Invoicing.ApplyApprovableDeterminationRulesToERS.
4. Click Yes.
5. Click Save, then click OK to confirm the changes.

The determination rules are applied to all ERS invoices created after the parameter was set to Yes.

Important: On sites using expression-based defaulting for invoice-related documents, invoices and invoice reconciliation documents must both have the same defaulting based on the determination rules in order for this fix to work. This means the expression must be defined for both InvoiceLineItem and InvoiceReconciliationLineItem. SAP Ariba sets  determination rules for you, so if you're still experiencing this issue after setting the parameter, have your designated support contact log a Case. An SAP Ariba representative will check the configuration of the determination rules.
