You Must Declare Identification

In ABAP Objects, the ID addition must be declared in IMPORT/EXPORT/FREE ... MEMORY statements.

In ABAP Objects, the following statements cause an error message:

EXPORT f TO MEMORY.
IMPORT f FROM MEMORY.
FREE MEMORY.

Correct syntax:

EXPORT f TO MEMORY ID key.
IMPORT f FROM MEMORY ID key.
FREE MEMORY ID key.

Cause:

Without identification, all programs in a call chain run in the same memory area. This leads to unpredictable results, particularly when complex transactions are being performed.
