This activity is used to certify a valuation. Once the items have certified values entered, the valuation can be certified. After certification, the amounts are recognized when the voucher is created.
Postings are created for the certified amounts using the Voucher Date, User Group and Voucher Type entered in the Certify Valuation dialog box. Note that an error message will be displayed if a default user group or voucher type does not exist.
If for some reason a valuation line item has a valuation value but no certified value, it will get the certified values copied from previous certified valuations. If there is no previous valuation in the Certified status, a zero amount will be copied.
If you override the retention for a contract item(s), and a maximum retention has been defined for the contract, an error message will be displayed at certification when the total retention for the item(s) exceeds the maximum retention.
When you are certifying the valuation and a contract item is withholding tax, the tax withholding tax code(s) and the corresponding tax rates on each item (retrieved when creating the valuation) are validated against the current tax withholding configuration for the supplier. If differences exist, a warning message is displayed giving you the opportunity to cancel the certification and refresh the tax withholding before certifying.
Note: When a valuation supersedes another valuation, and this valuation is completed though not certified, then certifying the latest valuation will automatically set the status of the older valuation to Archived.
If a project activity is connected to a contract item, used cost will be reported to the project when the application for payment related the item is received and when the item valuation is certified. When multiple currencies are involved, all calculations to reduce the committed cost when the used cost is reported are done in the transaction currency. The remaining committed cost is then converted to base currency, using the currency conversion rate valid to the system date, and updated to the project activity.
It is not possible to update a valuation that has been certified.
