Make use of the SUBMIT ...AND RETURN keyword in your first program so that the transfer is controlled to the 2nd program. After execution, control is returned back to 1st program.

Thanks

You have to use SUBMIT with additions EXPORTING LIST TO MEMORY and AND RETURN statements. Below example can help you understand. Report1:

DATA: i_list TYPE TABLE OF  abaplist.

WRITE:/ 'A'.

SUBMIT report2 EXPORTING LIST TO MEMORY AND RETURN.

CALL FUNCTION 'LIST_FROM_MEMORY'
  TABLES
    listobject = i_list
  EXCEPTIONS
    not_found  = 1
    OTHERS     = 2.

CALL FUNCTION 'WRITE_LIST'
  EXPORTING
    write_only = 'X'
  TABLES
    listobject = i_list
  EXCEPTIONS
    empty_list = 1
    OTHERS     = 2.

Report2:

WRITE:/'B'.
