A row already exists with this key Please see abap error for more details about the possible cause of this runtime error and how it could be avoided.

An attempt was made to insert an entry into table <runtime parameter>-NAME. Updating unique table key <runtime parameter> resulted in a duplicate entry however. The key in question could be either the primary key or a secondary key.

The key components of the duplicate entry have the values <runtime parameter> <runtime parameter> <runtime parameter> <runtime parameter>.

With primary keys, termination can occur during block insert operations. The can affect numerious statements, for example

(1) MOVE

(2) INSERT/APPEND ... LINES OF ... INTO/TO

(3) SELECT ... INTO/APPENDING ...

With secondary keys, termination can also occur due to a single record insert operation. In particular, the following modifying statements can cause the system to terminate due to duplicate key values as soon as the key is used again (delayed update):

(1) " = ..." or "-comp = ...", if the assignment to a field symbol or to a component of a field symbol modifies a component of a unique secondary key.

(2) "ref->* = ..." or "ref->comp = ...", if the assignment to a field symbol or to a component of a field symbol modifies a component of a unique secondary key.

(3) "MODIFY ... [TRANSPORTING comp_1 ... comp_n] ...", if transporting the components to be changed modifies a component of a unique secondary key.

(4) "COLLECT ... INTO ...", if adding up the columns of a numeric type modifies a component of a unique secondary key.

(5) "READ TABLE ... INTO ...[TRANSPORTING comp_1 ... comp_n] ...", if the field symbol points to a row of a table with unique secondary keys and transporting the values read modifies a component of a unique secondary key.
