How do I allow Business Network suppliers to create contract invoices by punching in?

First, enable the relevant transaction rule:

1. Sign in to your Buyer SAP Business Network account as the administrator.
2. Click [user initials] > Manage Profile > Default Transaction Rules.
3. Check the box next to Allow suppliers to access your SAP Ariba procurement applications for collaborative invoicing, requisitioning, managing time and expense sheets, and creating service sheets.
4. Click Save.

Second, the Buyer SAP Business Network account must also correctly configure the Business Application IDs and End Points (cXML and OData Setup) settings.

1. Configure the URL for the specific End Point for the selected SystemID.
2. Click Configure Document Routing > Document Type: Provider Setup Request set to above End Point.

Then, add the associated supplier user(s) to the group Supplier Invoice Entry User.

You can approve their User Profile (UP) request to add them in automatically:

1. Have the supplier punch in after enabling the transaction rule.
   This will generate a UP request in the procurement solution.
2. Sign in to your SAP Ariba procurement solution.
3. Approve the associated UP request.

Alternatively, if the UP request is missing or was auto-withdrawn prior to approval, add the supplier(s) to the group manually:

1. Sign in to your SAP Ariba procurement solution.
2. Click Manage > Core Administration > User Manager > Users.
3. If there are any filters besides email address, remove them via Add/Remove Search Filters.
4. Search for any supplier by email address.
5. Click Edit > Groups.
6. If the supplier does not have the group Supplier Invoice Entry User, add it by clicking Add/Remove > Supplier Invoice Entry User > Done > Save.

Finally, ensure that the supplier user has an associated, active partitioned user.
Approving the UP request will automatically generate a partitioned user, but if there is no UP request submitted, you may need to create the partitioned user yourself.
