Hi,

Try the following

data: gs_t001 type t001.

data: go_struct type ref to cl_abap_structdescr,
      gt_comp   type abap_component_tab,
      gs_comp   type abap_componentdescr.

start-of-selection.

  go_struct ?= cl_abap_typedescr=>describe_by_data( gs_t001 ).
  gt_comp = go_struct->get_components( ).
describe table gt_comp lines sy-tfill.

write: / sy-tfill.

And if you don't have the class cl_abap_typedescr, try something like this:

data: lv_count type i.

field-symbols: <field> type any.

do.
  assign component sy-index of structure YOUR_ITAB_STRUCTURE to <field>.
  if sy-subrc eq 0.
    lv_count = sy-index - 1.
  else.
    exit.
  endif.

enddo.

You haven't tried it the right way.

Does your internal table use a workarea? If so, look at my example and try that one. In no way that will return the number of entries in your internal table.

Some code perhaps?

How is your structure defined? Etc.

What i was afraid of.. your structure only has 1 column. Hence, your result equals 1.

edit:

Apparently, you have a '|' separated string in there.

Read a line from your internal table into a workarea.

Use SPLIT workarea TABLE lt_temp AT '|'

And then count the number of lines in lt_temp.

I assume all lines in your intenal table have the same structure, e.g. the same number of separated values.
