Retrieve list structure from LIST_FROM_MEMORY function

Former Member — Wed, 22 Sep 2010 14:15:21 GMT

Hi,

Is there a way that I can retrieve the structure of a list that was imported from memory.

I have a program that uses SUBMIT "program" EXPORTING LIST TO MEMORY and RETURN, then I use the function module LIST_FROM_MEMORY in order to retrieve the list, but is there a way I can determine what the structure of the list is? (field type, field length, etc).

Thanks,

Does it always require a structure to create/export a list?

Hello,

Maybe you can have a look at the function module : LIST_RESTORE_INFO

The function group SLST (via SE80) also contains a lot of other function modules concerning list processing.

I hope this can help you.

Success.

Wim

 DATA  BEGIN OF rlist OCCURS 0.
          INCLUDE STRUCTURE abaplist.
  DATA  END OF rlist.

CALL FUNCTION 'LIST_FROM_MEMORY'
    TABLES
      listobject = rlist.

 IF sy-subrc = 0.
    CALL FUNCTION 'LIST_TO_ASCI'
      EXPORTING
        list_index         = -1
      TABLES
        listasci           = itab
        listobject         = rlist
      EXCEPTIONS
        empty_list         = 1
        list_index_invalid = 2
        OTHERS             = 3.
