In a transaction i am filling a table in Table Control in Daiolgue programming in Module Pool.Which has first Coulmn as load types.The Load type has 11 entries like .(100,110,120...) . If i am changing an existing Load type say 100 to 120.Instead on deleting the Load type 100 and Inserting 120 in that Place. The Load type 120 is getting appened in the Table.and 100 is remaining same in the Table.
