Hi harikrishna indugu


data:
  lr_dynwa type ref to data.
field-symbols:
  <dynwa> like wa.
create data lr_dynwa like wa.
assign lr_dynwa->* to <dynwa>.

Now you can use <dynwa> like you use wa.

But I do not understand what it is good for.

If you do not have a structure wa but the name of the DDIC structure, then it goes like


data:
  lv_ddictype type tabname value 'BKPF', "just an example
  lr_dynwa type ref to data.
field-symbols:
  <dynwa> type any.
create data lr_dynwa type (lv_ddictype).
assign lr_dynwa->* to <dynwa>.

In this case, you can not access the fields of <dynwa> directly as i.e. <dynwa>-BELNR, this is a syntax error.

But you can ASSIGN COMPONENT 'BELNR' of structure <dynwa> to <ANY> if you declared a field-symbol <any> type any before.
