Outputlen: Changing the particular field output length.

Determines the column width of the field:? If the field has a reference to the Data Dictionary, you can leave the field set to

its initial value. In this case, the ALV adopts the output length of the relevant domain.

? For fields without reference to the DDIC, you must specify the desired fieldoutput length.LOOP AT i_fieldcat ASSIGNING .

CASE -fieldname.

when 'FULLTIMEEMPLOYEE'.-outputlen = '8'.

ENDCASE.

ENDLOOP.

Key: Making a field as key field if set or non-key field if not set.If this field is set, the ALV Grid Control color-codes the column as a key field and fixes this

column during horizontal scrolling. The order of the key columns in the ALV Grid Control can

be modified interactively. In contrast to the SAP List Viewer, the ALV Grid Control allows youto directly hide key columns with NO_OUT.

LOOP AT i_fieldcat ASSIGNING .

CASE -fieldname.

ENDCASE.

ENDLOOP.

No_out: If you set this field, you hide the relevant column in the list. Nevertheless, the column is

available in the field selection and can be interactively selected by the user as a display field. TheALV displays the contents of hidden fields on the detail screen for a row in the grid

control.LOOP AT i_fieldcat ASSIGNING .

CASE -fieldname.

when 'AGE'.-no_out = 'X'.

ENDCASE.

ENDLOOP.In change layout, the user can select the column and then make the field to appear in output.

Just: Relevant only to fields of data type CHARorNUMC. Justifications:

? 'R': right justified

? 'L': left justified? 'C': centered

How the column header is justified, depends on how the column contents are justified. You

cannot justify the column header separately.LOOP AT i_fieldcat ASSIGNING .
