Check a workbook with a dry run

A dry run reads every mapped row without writing records. Model validity and row acceptance are separate checks. Open a workbook draft with Model authoring and see Workbook onboarding and Issues and dry runs for the different results.

1. Expand Issues, history and dry run. Resolve blocking Issues in the model or profile first, then choose Dry run.
2. Check the draft version and comparison workspace. Wait for Checking… to finish. Checked is a completed check; Failed or Stopped is not. Read any failure and correct its cause before retrying or making the next mapping change.
3. Open each source tab. Read records created or updated, values, relationships, related records created and refused rows. These are different units, so do not add them as a row total.
4. Select a figure to inspect the rows behind it. Open the refused-row figure to read sheet, row number and reason. Correct an unresolved reference, wrong type or missing required value at its source or in the mapping. A valid draft can still refuse source rows.
5. After editing, wait for the new check. was compares with the previous result; it is not a count from an actual import. Use the result for the current draft version.
6. Account for every source and any remaining refusal before loading into a change set.

The eventual load can meet newer records or different workspace data. Review its actual result and change set too; a dry run is neither an import nor a publication.
