SAP Data Services is a data integration and transformation software application. It allows users to develop and execute workflows that take data from predefined sources called data stores (applications, Web services, flat-files, databases, etc.)
As other SAP products, there is excellent support by SAP on this tool. You can access the SAP Help portal in order to give support either from the huge community or directly from SAP.
SAP Data Services is better at integration with other SAP products and data sources with native HANA connectors. There are also accelerators to consider when looking at it as a data migration tool for SAP implementations.
