1. Go to the Customer Invoicing work center.
2. Go to the Invoice Requests view.
3. Select the invoice request XYZ.
4. Click the Invoice button.

The following error message occurs:"Invoice request XYZ item XX not possible; reference document inconsistent".

Inconsistencies can be caused by many reasons for example:

• Tax calculation is not applied correctly.
• Inconsistent Master Data for a Business Partner used in the reference document for example the Customer Account.
• Payment Terms are not set up correctly in Business Configuration.

The redetermination should be done on the sales order invoice request or any related preceding invoice request documents, such as customer contract invoice request:

1. Go to the Customer Invoicing work center.
2. Go to the Invoice Requests view.
3. In the Search field, enter the ID of the preceding sales document DEF (DEF represents the ID of the sales document for invoice request XYZ such as sales order, service order or customer contract).
4. Select the sales order invoice request which is inconsistent (if the preceding document is not a sales order select the respective invoice request).
5. Click the Check button which opens a new window showing further issue descriptions.
6. Solve the issues shown in that screen.
