Dear SDN Members,

when using methods

CALL METHOD GRID->SET_TABLE_FOR_FIRST_DISPLAY

I am getting a error ' Internal table is not type compatible with formal parameter it_outtab'

How to solve this ?

Thanx in Advance.

Check this program it may help u.

data: l_dref type ref to cl_abap_typedescr.

data: l_clref type ref to cl_abap_classdescr.

data: x_methods type abap_methdescr.

data: x_parameters type abap_parmdescr.

constants: query_class type seoclsname

value 'CL_GUI_ALV_GRID'.

• check if query_class exists in the current system

call method cl_abap_classdescr=>describe_by_name

exporting

p_name = query_class

receiving

p_descr_ref = l_dref

exceptions

type_not_found = 1

others = 2.

if sy-subrc <> 0.

exit.

endif.

l_clref ?= l_dref.

loop at l_clref->methods into x_methods.

write:/ x_methods-name.

loop at x_methods-parameters into x_parameters.

write:/ x_parameters-length,

x_parameters-decimals,

x_parameters-type_kind,

x_parameters-name,

x_parameters-parm_kind .

endloop.

skip 3.

give the whole body , ie sqare brackets and try

CALL METHOD W_GRID->SET_TABLE_FOR_FIRST_DISPLAY
    EXPORTING
      IS_LAYOUT       = WA_LAYOUT
    CHANGING
      IT_FIELDCATALOG = IT_FIELDCAT_WRT_OFF
      IT_OUTTAB       = <b>IT_WRT_OFF_FLDS[].</b>

<b>data : gt_sbook TYPE TABLE OF sbook.</b>

CALL METHOD grid2->set_table_for_first_display

EXPORTING i_structure_name = 'SBOOK'

is_layout = gs_layout

CHANGING <b> it_outtab = gt_sbook.</b>

Hello Johnn

If you are using an itab with header line then Chandrasekhar provided the solution. However, if you want to enter the ABAP-OO world you should get rid of these nasty header lines immediately using table types or just itabs without header line. Header lines are a mess that should never (ever) enter our coding.
