If you are unable to progress a Sales Order to invoicing using the Invoice Despatched Orders process then likely it is not meeting part of the requirement to be invoiced by the process itself.
To ensure your Order meets all of the requirements please use the following checklist:
The Despatch Note Progression Stage must state: Invoicing, this should also match the Sales Order Item Line, Waiting Invoicing.
If it's a Daily Run then customers must have Individual Invoice For Despatch = "Yes"
If it's a Weekly Run then customers that have Individual Invoice for Despatch = "No" and the Customer must be ready for invoicing based on their weekly invoicing settings and the Despatch Note Despatched Date must be <= The customer invoicing cut off date.
The Sales Order must have a total value greater than 0.00 and cannot be made up entirely of FOC items. If you use the Bespoke Function set WHIT, then the Despatch Note's Despatched Date must <= Today
If you are still unable to invoice the order using the Invoice Despatched Orders process after ensuring all these statuses match, then you will need to raise a ticket with support for this to be investigated.
