SAP Business ByDesign

1. Go to the Business Configuration work center.

2. Select the Overview view.

3. Open Fine Tuning Activity Document Numbering Formats for Customer Invoicing.

4. Click on Define document numbering formats for other countries/regions.

5. There are 2 rules created for the respective Company and Country:
   For Document Type Invoice the prefix AB is maintained and for Document Type Credit Memo the Prefix CD is maintained 

1. Go to the Customer Invoicing work center.
2. Select the Invoice Documents view.
3. Search for AB-XXX-2024. The Invoice Type is Credit Memo and the Total has a negative value.
4. Search for CD-XXX-2024. The Invoice Type is Credit Memo and the Total has a negative value.

You expect that both have the Prefix CD as per the rule defined. 

The scoping element Invoice and Credit Memo Items in Customer Invoice Request is In Scope in your system. This means that you can create Manual Invoice Requests or Manual Credit Memo Requests that include both Invoice Items (with a positive amount) and Credit Memo Items (with a negative amount).

If you create different document numbering rules with different Prefix in the Fine Tuning Activity Document Numbering Formats for Customer Invoicing for the Document Type Invoice and for Document Type Credit Memo, the system will use the corresponding prefix depending on the positive or negative overall Total of the Invoice when the Invoice is created.

When AB-XXX-2024 was created the total overall amount was positive and the amount was then changed to an overall negative amount.

This is the expected system behaviour.
