Bulk Operations

What a mass update and a mass delete do, how every change is previewed before it commits, why the work runs as you through each application's own rules, and why a bulk change cannot be undone.

Change one or more fields on many records at once, from a list of query or search results or from the Mass Updates wizard, with a preview before anything changes.

Remove many records of one type in a single operation, from a results list or the Mass Deletes wizard, after previewing exactly which records will go.

How a mass update works out each field's new value — fixed values, expressions, file cells, multi-select list syntax, custom fields, blanks, numbers, and spreadsheet dates.

What the preview spreadsheet, the results spreadsheet, the completion screen, and the completion email of a mass update, mass delete, or custom data task contain, and how to read them.

The rules that refuse a bulk operation before it runs, the limits on how much one run can do, what Rhythm does not protect you from, and why a completed bulk change cannot be undone.

What to check when a mass update or mass delete reports errors, says it succeeded but nothing changed, refuses your file, gets stuck, or changes records you did not expect.
