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

You can limit the maximum number of characters for service sheet and invoice numbers by following the below steps:

1. Sign in to the SAP Business Network
2. Click Administration > Configuration
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

The Ship Notice Number Preferences feature was designed only for Supply Chain Collaboration buyers, therefore if your account is not Supply Chain Collaboration(SCC), it won't work.

For regular buyers (non SCC buyers), a customization is required to set Number Preferences for Advanced Ship Notices. Please reach out to your Ariba Customer Engagement Executive (CEE) directly for such request.
