This activity is used to uncertify a valuation. It is not always recommended to uncertify a valuation, and the consequences of uncertifying must first be identified, since the certificate may have already been sent to the supplier. However, if necessary, you (the sub contractor) have the possibility to update the valuation. This gives you more flexibility instead of having the valuation in the Certified status, at which stage it is only possible to continue with payments.
Once the valuation is uncertified, all the certified values entered will remain, including previous valuations that were archived or cancelled. Note: The status of the valuation is changed back to Certification In Progress and certified postings will be reversed. Therefore application posting must be recreated.
