Item List and CUOBJ_LIST

Appending items to an item list:

REFRESH CUOBJ_LIST.
CUOBJ_SINGLE-NO = 1.
CUOBJ_SINGLE-OBJ = CU_ITEM.
APPEND CUOBJ_SINGLE TO CUOBJ_LIST.
         

Assigning the item list to the parameter CUOBJ_LIST in the method ADD_CU_BUNDLE:

CALL METHOD GP -> IF_GRAPHIC_PROXY~ADD_CU_BUNDLE
EXPORTING       PORT = CO_PORT_CHART
KEY = <variant key>
BUNDLE = <customizing bundle for point>
CUOBJ_LIST = CUOBJ_LIST
IMPORTING       RETVAL = RETVAL.
         

There can be several item lists so the application can assign a different one each time it calls the method ADD_CU_BUNDLE. The application calls ADD_CU_BUNDLE once for each variant key.
