Answers 1:- Within a main session, when ever you start an application program, it opens up an internal sessions with in the main session. The internal session has a memory area that contains the ABAP program and its associated data.  So when ever you want to  pass data between two internal sessions, then you can use ABAP Memory (i.e import, export). When comes to SAP memory (also known as global memory), if the data has to be passed b/w two main sessions, we can use SAP Memory(SPA/GPA Parameters).  SAP Memory can also be used to pass data b/w internal sessions. Neelima Answers 2:- SAP MemorySAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another.  Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens ABAP/4 MemoryABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass datato a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse. SAP memory The SAP memory, otherwise known as the global memory, is available to a user during the entire duration of a terminal session. Its contents are retained across transaction boundaries as well as external and internal sessions. The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory.  ABAP/4 memory The contents of the ABAP/4 memory are retained only during the lifetime of an external session (see also Organization of Modularization Units). You can retain or pass data across internal sessions. The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.  (二)         Passing data from one ABAP program to another 1. You have to define an internal table ITAB in program AAA.  2. In the program AAA you export your ITAB to the memory.    EXPORT ITAB TO MEMORY ID TD(ID is the name of memory, you dont need to create it ).  3. In program BBB you have to declare The same table (same tables name and same fields).  4. In BBB you can import ITAB :    IMPORT ITAB FROM MEMORY ID TD  5. Now you can export it to AAA after modifications.    EXPORT ITAB TO MEMORY ID TD 6. In AAA :    IMPORT ITAB FROM MEMORY ID TD This solution is independant to SUBMIT.  (三)         Example:     两个程序010和011,选择屏幕是一样的. 010是ALV行显示的,011是WRITE显示的.需要达到的效果是: 点击:MATNR字段则将010的选择屏幕传到011的选择屏幕中去;点击VBELN,则将当前行的VBELN传到011的选择屏幕中去. Program:010 1.定义010的选择屏幕: selection-screen begin of block b1 with frame title bt1.  parameters  PL_BUKRS like VBRK-BUKRS memory id P_BUKRS default 1000.  select-options PI_KUNRG for VBRK-KUNRG.  select-options PI_FKDAT for VBRK-FKDAT.  select-options PI_VBELN for VBRK-VBELN.  select-options PI_VGBEL for VBRP-VGBEL.selection-screen end of block b1. 2.在010中定义USERCOMMAND事件: form. user_command using i_ucomm like sy-ucomm is_selfield type slis_selfield. case i_ucomm. when IC1. CASE is_selfield-fieldname. WHEN VBELN. read table itab index is_selfield-tabindex.      change EXPORT ITAB-VBELN TO MEMORY ID PT_VBELN. EXPORT is_selfield-fieldname TO MEMORY ID PP_FIELD. CALL TRANSACTION ZF011 AND SKIP FIRST SCREEN. WHEN MATNR. EXPORT is_selfield-fieldname TO MEMORY ID PP_FIELD. EXPORT PI_KUNRG to memory id PP_KUNRG.   add EXPORT PI_VGBEL TO MEMORY ID PP_VGBEL.   add EXPORT PI_VBELN to memory id PP_VBELN.   add EXPORT PI_FKDAT TO MEMORY ID PP_PKDAT.   add CALL TRANSACTION ZF011 AND SKIP FIRST SCREEN. ENDCASE. endcase. endform. user_command 3.在011中定义选择屏幕(这里就不需要定义MEMORY ID拉): selection-screen begin of block b1 with frame. title bt1. parameters PL_BUKRS like VBRK-BUKRS memory id PP_BUKRS default 1000. select-options PI_KUNRG for VBRK-KUNRG . select-options PI_FKDAT for VBRK-FKDAT. select-options PI_VBELN for VBRK-VBELN . select-options PI_VGBEL for VBRP-VGBEL . selection-screen end of block b1.   4.在011中接收010中传过来的值 DATA : ME_VBELN LIKE VBRK-VBELN . DATA : ME_FIELD(30) TYPE C . “定义ME_FIELD是为了接收is_selfield-fieldname的MEMORY ID PP_FIELD,因为MEMORY不是一个字段,也不是一个内表,只能用这种方式来传输 CLEAR :ME_VBELN ,ME_FIELD. IMPORT is_selfield-fieldname ME_FIELD FROM MEMORY ID PP_FIELD. IF ME_FIELD VBELN. IMPORT ITAB-VBELN ME_VBELN FROM MEMORY ID PT_VBELN. ELSE . IMPORT PI_VBELN PI_VBELN from MEMORY ID PP_VBELN. ENDIF . IMPORT PI_FKDAT PI_FKDAT FROM MEMORY ID PP_PKDAT. IF NOT ME_VBELN IS INITIAL .  “表示选择了VBELN PI_VBELN-SIGN I. PI_VBELN-OPTION EQ. PI_VBELN-LOW ME_VBELN .  “只选择单值,所以传LOW就可以拉 APPEND PI_VBELN .
