i have taken target table as my lookup table using static cache.in source i have duplicate values.

in mapping i ahve used update strategy transformation but not i m not able update data in target table

Example:Initially(i mean after session Load)

source table Lookup table Target table

ID    Name           ID    Name            ID    Name    
1     A              1     A               1     A 
2     B                                    2     B

Now im inserting two more records

3      C
1      E

but its not updating below record

1    E

i am getting below error

One or more values in the INSERT statement, UPDATE statement, or foreign key update caused by a DELETE statement are not valid because the primary key, unique constraint or unique index identified by "1" constrains table "TABLE_NAME" from having duplicate values for the index key.

I know if i use dynamic lookup it will work correctly but in static. please give the reason ASAP.
