Have a derived dataset that has been published multiple times.

You can find changes in datasets and tables easily and securely to help you debug any issues encountered during dataset publishes. You can select 2 publish activities of a dataset to compare changes made to its pipeline between snapshots.

A pipeline is a collection of datasets and tables that are upstream from a dataset and comprise the upstream lineage until it reaches base datasets or tables.

Workday displays the

Pipeline Snapshot Comparison

report and highlights all changes made between pipeline snapshots using a color scheme defined in the legend.

Workday opens the

Pipeline Snapshot Comparison

report and displays information you have permission on. Workday displays different information depending on the component:

Component	Description
Dataset and Table List	Workday lists the upstream datasets and tables in the pipeline that impact this dataset. The report displays datasets and tables you have at least Dataset Viewer permission on.
Comparison Window	Workday: Displays a side-by-side comparison of the stages in the selected dataset or table. Highlights any differences between snapshots. Workday displays different information depending on your permissions. The window displays the stage information if you have either of these permissions on the dataset selected: Dataset Editor. Dataset Viewer permission, and your tenant is configured to enable the Enable Prism Dataset Transformations check box. The window displays View the output fields if: You have Dataset Viewer permission, and your tenant is not configured to enable the Enable Prism Dataset Transformations check box. The dataset imports a dataset or table you don't have Dataset Viewer permission on. You select a table. If you see the details for only 1 snapshot, then the dataset or table selected was either added or removed from the pipeline between snapshots.
Color Legend	The definition of what each highlighted color represents.

Click the stage in the comparison window to compare the details between activities. You can view the definition, calculated fields, and output fields of the selected stage.
