The SAP accelerator for the order to cash process is now available. It provides sample pipelines that you can use to build your end-to-end order to cash process and analytics with Cloud Data Fusion, BigQuery, and Looker. The accelerator is a sample implementation of the SAP Table Batch Source plugin, which enables bulk data integration from SAP applications with Cloud Data Fusion. The accelerator is available in Cloud Data Fusion environments running in version 6.3.0 and above.

In Cloud Data Fusion version 6.4.1, Replication supports the Datetime data type in BigQuery targets. You can now read and write to tables that contain Datetime fields.
Fixed in 6.4.1 (for more information, see the CDAP release note):
Fixed an issue that caused pipelines with aggregations and Decimal fields to fail with an exception.
Fixed the Join Condition Type so that it is displayed in the Joiner plugin for pipelines that were upgraded from versions before 6.4.0.
Fixed Wrangler so that pipelines fail when there is an error. In Wrangler 6.2 and above, there was a backwards-incompatible change where pipelines did not fail if there was an error and were instead marked as complete.
Fixed an issue that prevented new previews from being scheduled after the preview manager had been stopped ten times.
Fixed an issue while writing non-null values to a nullable field in BigQuery.
Fixed an issue in the BigQuery plugins to correctly delete temporary storage buckets.
Fixed an issue in the BigQuery sink that caused pipelines to fail when the input schema was not provided.
Fixed an issue in the BigQuery sink that caused pipelines to fail or give incorrect results.
Fixed an issue that caused pipelines to fail when a Pub/Sub source Subscription field was a macro.
May 05, 2021
There is an issue in the BigQuery sink plugin version 0.17.0, which causes data pipelines to fail or give incorrect results. This issue is resolved in BigQuery sink plugin version 0.17.1. For more information, see the Cloud Data Fusion Troubleshooting page.
March 31, 2021
Features in 6.4.0:
GA: You can now ingest data from SAP tables with the SAP Table Batch Source plugin.
- BigQuery batch source
- BigQuery sink
- BigQuery multi table sink

You can configure machine type, cluster properties, and idle TTL for the Dataproc provisioner. For the available settings, see the CDAP documentation.
Adding, editing, and deleting comments on draft data pipelines is now supported. For more information, see Adding comments to a data pipeline.
Advanced join conditions are now available in the Joiner plugin. You can specify an arbitrary SQL condition to join on. For more information, see Join Condition Type.
A new post-action plugin is now available: GCS Done File Marker. To help you orchestrate downstream/dependent processes, this post-action plugin marks the end of a pipeline run by creating and storing an empty
SUCCESSfile in the given GCS bucket upon a pipeline completion, success, or failure.
Changed in version 6.4.0:
- Behavior change: When you validate a plugin, macros get resolved with preferences. In previous releases, to validate a plugin's configuration, you had to change the pipeline to remove the macros.
Behavior change: Cloud Data Fusion now determines the schema dynamically at runtime instead of requiring arguments to be set. Multi sink runtime argument requirements have been removed, which lets you add simple transformations in multi-source/multi-sink pipelines. In previous releases, multi-sink plugins require the pipeline to set a runtime argument for each table, with the schema for each table.
You can now filter tables in the Multiple Database Tables Batch Source.
Multiple Database Batch Source and BigQuery multi-table sink have better error handling and let pipelines continue if one or more tables fail.
Cloud Data Fusion Replication changes:
- Renamed Replication pipelines to Replication jobs.
- The Customer-managed encryption key (CMEK) configuration property is now available for BigQuery targets in your Replication jobs.
- On the BigQuery Target properties page, renamed the Staging Bucket Location property to Location.
- Improved reliability by restarting Replication from the last known checkpoint.
You can now use files with ISO-8859, Windows and EBCDIC encoding types with Amazon S3, File and GCS File Reader batch source plugins.
Cloud Data Fusion now supports running pipelines on a Hadoop cluster with Kerberos enabled.
Fixed in 6.4.0 (for more information, see the CDAP release note):

- FTP batch source now works with empty File System Properties.
- Strings are now supported in Min/Max aggregate functions (used in both Group By and Pivot plugins).
