To do this, the key fields of all To make the data from an ABAP CDS view available in SAP Data Intelligence Cloud (Replication engine), you need to specify annotations for the view in the ABAP To implement target-based changed data capture, you must use the Table_Comparison transform. Azure Data Factory is an ETL and ELT data integration platform as a service (PaaS). Note. The CDC option is applicable for specific data types and only when you create new datastores. Change Data Capture (CDC) is a software technique to keep track of data changes due to either data modification language (DML) such as insert, update and delete SQL statements or data definition language (DDL) such as create table, Change data capture (CDC) SAP Data Services locates and extracts only data that changed since the last refresh.
