Need your suggestion for below points on service process in DSN:
1)With multiple service sub item in DSN we are not able to create invoice. if we try to create invoice for both items it automatically moves to rejected status with error "The tax information at invoice line 1000100010 does not match the tax information in the PO". Please find attachment for reference
2) Feasibility to check if supplier can create partial invoice for service items, if so what needs to be done.
3) Multiple Service entry sheet creation cannot be created by supplier at once , is this standard behavior ?
For your first item ,If the taxes for an invoice are zero, then the supplier must enter "0" for the tax amount. Tax values that are left blank will be considered as different than zero. If you are already doing that then this might be a bug . Would recommend creating a service request on connect.ariba.com
Don't believe partial invoice for service items is currently supported . Might have to create an Improvement request.
