Cancel Invoice
Explanation
This activity is used to cancel an invoice. You can perform this activity if 
something has been done incorrectly. For example, when invoice amounts are 
inaccurate, when an invoice has been linked to the wrong supplier or the 
supplier has sent the invoice to the wrong sub contractor.
When the offset or payment is rolled back, the supplier invoice will normally 
be cancelled by using the Copy and Cancel functionality in the 
Manual Supplier Invoice window.
Prerequisites
  - Standard prerequisites on the 
	Manual Supplier Invoice 
  window apply.
System Effects
	- The status of the valuation is set to Partially Invoiced or 
	Certified depending on whether the amount covers the whole valuation or 
	not.
- The status of the payment remains unchanged.
- The value in the Matched Amount field will not be included in any 
	calculation henceforth as the invoice is in the Cancelled status.
