You can compare two versions of a source-controlled asset to find out what's changed between the versions. You might want to do a comparison to troubleshoot an issue or share coding changes for peer code reviews.
You can compare versions of the following types of assets:
•Mappings (including mappings in advanced mode and mappings in SQL ELT mode)
•Mapplets
•Mapping tasks
•Data transfer tasks
•Dynamic mapping tasks
•Replication tasks
•Synchronization tasks
•Linear taskflows
•Fixed-width formats
•Saved queries
•Shared sequences
•User-defined functions
You can compare the current version of the asset which hasn't been committed to the repository yet to a version in the repository, or compare two versions that were committed to the repository.
The Compare Asset Versions page displays the selected versions in text format with highlights that indicate the differences, as shown in the following image:
Note: If the result of the asset comparison includes 10,000 lines or more, an error message appears. To compare large assets, use the Git compare feature within the Git repository.
1On the Explore page, navigate to the asset that you want to compare.
2In the row that contains the asset, click Actions and then click Compare Asset Version.
3To compare the current version to a version that's been committed to the repository, select Compare the current asset version and a previous asset version, and then select the previous asset version that you want to use.
4To compare two previous versions, select Compare two previous asset versions, and then select the two versions that you want to compare.
5Click Next.
The two versions of the asset appear in text format. Differences between the two versions are highlighted.
