Approve with missing data check box in the AP Unapproved Invoice Entry form header, Reviewers tab.

Select this check box if your review process requires this reviewer to approve all applicable lines for this invoice even though some required data is still missing. This allows the reviewer to approve invoices that lack data, which allows the invoice to progress in the review process. The missing data must still be entered before posting, but can be entered at some time after this reviewer's approval.

The default value comes from the setting for this reviewer in the HQ Reviewer Group form or the HQ Reviewers form.

Changes you make to this check box will update every line of this invoice that the reviewer is assigned to. If instead you want to make changes for specific lines only, make the change on each of those lines.
