We will use the example of a Contract in this case.

1. Go to the Customer Invoicing Work Center.
2. Go to the Invoice Requests View.
3. Search for Scheduled Invoice Request ABC  and select it.
4. Click Invoice, then the error messages for each item are raised: 'Invoice request ABC item XX not possible; reference document inconsistent' on the Invoice screen.
5. Go back to the Invoice request worklist.
6. Show all.
7. Search for Customer Contract Invoice request DEF.
8. Customer Contract Invoice request is inconsistent.
9. Select it, click Check, then another error is displayed:  'Payment method not allowed for payer ZZZ' (ZZZ represents the Customer Account)

You use SEPA Mandates for the Direct Debit Payment Method and the validity of the Mandate has expired and/or is not valid at the Pricing Date and the Invoice Date of the Contract or Sales Order. 
The system cannot identify a valid Payment Method for this account and raises error messages.

1. Go to the Account Management Work Center.
2. Go to the Account View.
3. Search for  ZZZ' and select it.
4. Click on Edit.
5. Navigate to the Financial data- Payment Data tab, you will see the Direct Debit payment method is maintained for this account.

Please verify that your SEPA Mandate is still valid and that Invoice ABC is within the valid timeframe. To ensure the validity of the SEPA Mandate, check the Pricing Date in the Pricing and Invoicing tab and the Pricing sub tab of the corresponding Contract or Sales Order.

Additionally, make sure that the SEPA Mandate is still valid at the Invoice Date of the relevant Customer Contract Invoice Request or Sales Order Invoice Request, which is determined from the Creation Date of the Contract or Sales Order.

After completing these steps, ensure the consistency of the respective Customer Contract Invoice Request or Sales Order Invoice Request using the following steps:

1. Go back to the Invoice request View.
2. Show all.
3. Search for Customer Contract Invoice request DEF.
4. Customer Contract Invoice request is inconsistent.
5. Select it, click Check
6. Click on Redetermine All
