使用如下report 测试ABAP memory:

REPORT ztest_export.
DATA: lv_memory TYPE char10 VALUE 'memory_id',lv_v1     TYPE string VALUE 'test1',lv_v2     TYPE string VALUE 'test2',ls_v3     TYPE comm_product,lv_task   TYPE char8 VALUE '001'.ls_v3 = VALUE #( product_id = 'MCF-0001' product_type = '02' ).
EXPORT value1 = lv_v1 value2 = lv_v2 value3 = ls_v3 TO MEMORY ID lv_memory.WRITE: / 'test by normal function call...' COLOR COL_NEGATIVE.CALL FUNCTION 'ZIMPORT_TEST'.WRITE: / 'test by starting new task...' COLOR COL_GROUP.CALL FUNCTION 'ZIMPORT_TEST' STARTING NEW TASK lv_task PERFORMING import ON END OF TASK.WRITE: / 'Call via DESTINATION NONE...' COLOR COL_KEY.CALL FUNCTION 'ZIMPORT_TEST' DESTINATION 'NONE'.FORM import USING id TYPE clike.WRITE: / 'Executed in PERFORM on end of task...' COLOR COL_KEY.IMPORT value1 = lv_v1 value2 = lv_v2 value3 = ls_v3FROM MEMORY ID lv_memory.WRITE: / 'Value1: ' , lv_v1 COLOR COL_NEGATIVE,/ 'Value2: ' , lv_v2 COLOR COL_TOTAL,/ 'Product ID: ', ls_v3-product_id COLOR COL_GROUP,'Product Type: ', ls_v3-product_type COLOR COL_POSITIVE.
ENDFORM.

根据SAP help里的定义，ABAP memory只能用于在同一个external session下的不同internal session之间共享数据。因此上述report的三种测试scenario，只有第一种normal call的方式能够成功import到memory里的数据:
