If you change the sender of a document in Verify, and there is a document definition associated with that sender, you can choose to have Verify reinterpret those documents. To do this, select in the Verify job description Control settings or (if you are using an inbox) in the dialog.
Reinterpretation is also performed if the sender is changed in the document definition (most commonly during optimization) after one or more documents were interpreted. This can happen if you interpret several documents of the same type without verifying them. The document definition does not have to be complete for a document to be reinterpreted.
Note: There is a related setting in Eiglobal.ini, namely CopyOldValuesWhenReInterpret.
The option to reinterpret a document is provided automatically when the Verify operator changes what is considered to be the last page of a document.
It is also possible to reinterpret a document directly in Verify at any time by selecting Document > Reinterpret. Note that this does not apply to XML documents.
