  23. R3 Table List

  24. SQL server ABAP Dictionary R/3 work process Database Access Agent R/3 maintains definitions of the database objects it uses in its integrated ABAP Dictionary. The R/3 definitions are mapped to the SQL Server definitions. Application server ABAP Dictionary object <TABLE > 1 2 } Key Data Database server <SID> SQL Server object <TABLE > 1 2 } Key Data

  25. Transparent Tables ABAP Dictionary Table definition in ABAP Dictionary 1 2 TABA } Key Data SQL Server database <SID> 1 2 1 3 1 4 TABA~0 (Unique clustered index) Table and index in SQL Server TABA (Table)
