I am very sure we are not using dynamics to it full potential. currently, on SL
Though, if we accidently charge Tax on a Sales Order that was invoiced. (mind you we have to have 4 people involved in the process)
1 we have to ask a Admin person to issue a credit against the original Sales Order. then I have to re-write a new Sales Order. Leave it open.
They issue the credit memo, send it to AR to do the Invoice. then release the new Sales Order to be invoiced with out tax.
After all that no one knows(I mean this) are the parts put back into inventory on the CM then removed with the new Sales Order??
