Void an Invoice from a Previous Year

Good morning -

Client has about 200 F4211 - SO Detail records from previous years that are at Next Status 620.  The invoices have been run for all lines, they all have the Invoice Number,

Invoice Doc Type, invoice Company, and Invoice Date assigned.  The client did not fix the errors as they occurred, that's why the F4211 lines are still at
Next Status 620, ready for Sales Update.

The client is now working on fixing the errors in Sales Update that prevented them from being fully updated the first time around. However, they are running into

an error, as Sales Update will not process lines with an Invoice Date from a previous year.
