The report

What the run did: what was written, what was not and why.

When it appears

When a run ends. Closing it keeps the run.

The short report

All parameters set — when nothing needs attention: how many parameters were written, how many were already correct, and Details to see more.

The short report after a clean run

The full report

Run completed — N parameters need attention — or Details from the short report:

The full report with the outcome bar, Operations and Element details, one reason group opened

Part	What it shows
Outcome bar	One bar and a count per outcome: set, excluded or read-only, failed, could not apply, unchanged. Values that were already right, or already filled with Only if empty, are listed apart — they are not problems
Duration / Throughput	How long the run took and how many parameters per second
Operations	One row per operation with its own outcome
Element details	Every element that was touched, grouped by outcome and then by reason (`Value does not fit the type`, `Target parameter is read-only`, `Member of a model group`…). The chips above filter by outcome; Filters narrows by operation, category, document, element name or ID
Documents	With several models: each model's own result

What the outcomes mean

Outcome	Meaning	What to do
set	Written	—
excluded or read-only	Skipped on purpose (an Exclusions option, a busy element) or the parameter cannot be written	Check the exclusions, or the parameter
failed	Revit refused the value	Usually a value that does not fit the parameter's type — text into a number
could not apply	The operation cannot do its job on this element	E.g. Zero Padding on a number parameter, which cannot hold leading zeros
unchanged	Left as it was by the rules	Expected for Map Values' Leave unchanged and similar

Every reason the report can give, with what to do about it, is listed in Report reasons.

Buttons

Button	What it does
Undo this run	Takes back everything the run wrote, in one step. Not offered after Synchronize with Central after the run
Export report	Saves the elements that were not written to a CSV file — see below. Appears only when something was not written
Open folder	Opens the folder of the exported file
Done	Closes the report and keeps the run — it is then a single entry in Revit's Undo list

Export report writes SkippedElements_<date>_<time>.csv next to the .fdc (in the temp folder if that folder cannot be written), with the columns ElementId, FamilyName, FamilyTypeName, Reason, DocumentName, OperationName. Useful for sending a colleague the list of elements they hold.
