Length report double

sanju_joseph — Sun, 18 Oct 2009 17:08:33 GMT

Hi,

I have the code below and i am not sure why the length of the attribute are reported double

Code:

FIELD-SYMBOLS:

<fs_comp_wa> TYPE abap_compdescr.

DATA: lr_desc_table type ref to CL_ABAP_TYPEDESCR,

lr_desc_struc type ref to cl_abap_structdescr.

lr_desc_table ?= cl_abap_typedescr=>describe_by_data( ZTEST).

if lr_desc_table->type_kind = 'u'. " <- Structure

lr_desc_struc ?= lr_desc_table.

loop at lr_desc_struc->components ASSIGNING <fs_comp_wa>.

"check the length of the field at run time '<fs_comp_wa>-length'

ENDLOOP.

endif.

Regards,

Sanju

You used 'ZTEST' as a test object. How is this object defined in the data dictionary? It's hard to reproduce without us knowing what this 'ZTEST' is all about.

I did, I even tried several structures from DD, but they all seem to have a different TYPE_KIND (not equal to 'u').

Well in my example ZTEST is the standard table , it;s really strange that even after adding a stucture you are not getting u,well what you can do next is to ignore the if condition and execute the remaining statement

lr_desc_table ?= cl_abap_typedescr=>describe_by_name( 'BUT000' ).

Descibe by data does not work for me, so I used statement above.

And that works just fine for me. No double entries.
