ABAP submit程序获取ALV数据的方法

1、使用标准ALV类方法

数据定义
field-symbols  : <lt_pay_data>   type any table .
field-symbols : <lt_test> type any . "LIKE LINE OF  it_tab .
data lr_pay_data              type ref to data.


具体用法
cl_salv_bs_runtime_info=>set(    exporting display  = abap_false
    metadata = abap_false
  data     = abap_true ).

  submit zwm001 with selection-table  lt_sel_tab  exporting list to memory and return.

  try.
      cl_salv_bs_runtime_info=>get_data_ref( importing r_data = lr_pay_data ).
      assign lr_pay_data->* to <lt_pay_data>.
    catch cx_salv_bs_sc_runtime_info.

      message `Unable to retrieve ALV data` type 'E'.
  endtry.

  cl_salv_bs_runtime_info=>clear_all( ).
  cl_demo_output=>display_data( <lt_pay_data> ).

2、使用memory

  submit zwm001 with selection-table  lt_sel_tab  exporting list to memory and return.

  call function 'LIST_FROM_MEMORY'
