We have a requirement to load full table data and get only last 7 days data from OLTP to OLAP.
My approach is as follows:
1. Connect to OLTP using SSIS and load as a dimension table to store full table records or except last 7 days
2. Have 2 connections (dsn) in SSAS so that we query the Full table from DWH db, and using OLTP DB (dsn) connection we could create a named query for last 7 days which would give me the latest.
Is there any better approach to handle this requirement?
