Deleting all Rows of a Table 
You can use SQL Studio to delete all rows of a table.
You have the required user authorizations.*
1. In the Catalog Manager, select the table for which you want to delete the rows.
2. Choose Catalog Manager ® Delete All Rows

If you delete the rows of a synonym, you thereby delete the rows of the original database table.
*For an explanation
of user authorizations, see the
User Concept
section of the documentation The SAP DB Database System.
