How to restrict the maximum number of characters for service sheet and invoice numbers?

You can set a maximum number of characters for service sheet and invoice numbers in SAP Business Network by updating the document number preferences.

1. Sign into your SAP Business Network account.

2. Click [User Initials] > Manage profile.

3. Click Document Number Preferences.

4. Under Invoice, click Create.

   • Enter the desired character limit in the box to the right of Maximum length.

   • Click OK.

5. Under Service Sheet, click Create.

   • Enter the desired character limit in the box to the right of Maximum length.

   • Click OK.

You can also specify which characters can be used:

• Tick Include numbers

• Tick Include uppercase letters

• Tick Include lowercase letters

For special characters, you can:

• Allow all characters

• Specify only the characters you want suppliers to use

• When creating character limits for invoices or service sheets, you must select at least one option (numbers, uppercase, lowercase, or special characters). If no option is selected, suppliers will receive the following error:
  “Error: Required format: Maximum length: XX, Includes special character”

• The Ship Notice Number Preferences feature is only available for Supply Chain Collaboration (SCC) buyers. If your account is not enabled for SCC, this option will not work.

• For non-SCC buyers, a customization is required to set number preferences for Advanced Ship Notices. To request this, please contact your Ariba Customer Engagement Executive (CEE) directly.
