Hi ​@DivyaSubramanian,

You can add Project in Manual Supplier Invoice pre posting (Go to Manual Supplier Invoice → RMB Header and select “Pre Posting” → Add Project Activity Sequence No.) Or esle you can add Project as a Code Part in invoice line as well.

Further if the Invoice is matched with a Project connected Purchase Order, project details will be fetched in the invoice as well.

Best Regards,

Rasangi
