Structure creation

[Former Member]

I guess I got a funny ques.. can someone answer this ?

I want to create a structure, with fields, a1,a2,a3...a10

is that possible I create some kind of counter, a(counter) and then keep on incrementing it without defining a1...a10

if it is possible, how do i acheive it ?

thanks.

You mean within a program? If so, then yes, you can create a dynamic internal table and then a dynamic work area. See this blog for an example.

So using what is in the blog, you code would be something like this. Run the program and check <dyn_wa> to see that it has your structure.

type-pools : abap.

field-symbols: <dyn_table> type standard table,
               <dyn_wa>,
               <dyn_field>.

data: dy_table type ref to data,
      dy_line  type ref to data,
      xfc type lvc_s_fcat,
      ifc type lvc_t_fcat.

data: index(2) type c.

start-of-selection.


  do 10 times.
    clear xfc.
    index = sy-index.
    concatenate 'A' index into xfc-fieldname.
    xfc-datatype = 'C'.
    xfc-inttype = 'C'.
    xfc-intlen = '10'.
    append xfc to ifc.
  enddo.



* Create dynamic internal table and assign to FS
  call method cl_alv_table_create=>create_dynamic_table
               exporting
                  it_fieldcatalog = ifc
               importing
                  ep_table        = dy_table.

  assign dy_table->* to <dyn_table>.

* Create dynamic work area and assign to FS
  create data dy_line like line of <dyn_table>.
  assign dy_line->* to <dyn_wa>.

  check sy-subrc  = 0.
