We are initial a new project, the data source is ECC system, from my knowledge there are three ways to populate SAP ERP data to target using DS
1. Use ABAP data flow in SAP Application data store
2. Use SAP table in SAP Application data store
3. Directly access ECC database as a general rdbms
Can anyone advice what's the characters of each option, from my understanding opention 2 cannot use SAP table as lookup table, any other dissadvantages ?
