CL_ABAP_TABLEDESCR

[Former Member]

How can I use this class to retrieve the number of

records an internal table contains?

Hello,

I don't know if it's possible to recover the number of records of an internal table using this class, but I suggest you to use the function LINES( itab ) to do this.

hi,

You can do this way ..

data : v_lines type i.

 describe itab lines v_lines.
 write v_lines.

I think finding number of records in a itab using this class is not possible.

If you want find the number of fields in an itab then

g_tabledescr type ref to cl_abap_tabledescr,
g_tabledescr ?= cl_abap_tabledescr=>describe_by_data( itab ).

But you can try this way

v_lines = lines( ltab ).

A small correction to this..

If itab is a table with header line,

g_tabledescr type ref to cl_abap_tabledescr,
g_tabledescr ?= cl_abap_tabledescr=>describe_by_data( itab ).

will raise cx_sy_move_cast_error because it returns cl_abap_structdescr instance.

It should be

g_tabledescr type ref to cl_abap_tabledescr,
g_tabledescr ?= cl_abap_tabledescr=>describe_by_data( itab[] ).
