Create deep structure to disable some cells in Dynamic ALV GRID

Question

Hi,
I want to disable some cells in a Dynamic ALV Grid before calling "SET_tABLE_Display" Method.
I check the BCALV_EDIT_02, where some cells are grayed out by assign the  CL_GUI_ALV_GRID-MC_STYLE_DISABLED  to the field name.
But I want the same using Field symbol.
I'm creating Dynamic table and dynamic structure based on the Dynamic field catalog.
Example: <FT_TAB> TYPE STANDARD TABLE,
                <FS_TAB> TYPE ANY,            
DATA: INT_TAB  is my dynamic table values.
For the INT_TAB internal table, I created dynamic Structure and dynamic field symbol table.
LOOP AT INT_TAB.
ASSIGN COMPONENT 'MATNR'  OF STRUCTURE <FS_TAB> TO <F_VALUE>
<F_VALUE> = INT_TAB-MATNR.
APPEND <FS_TAB> TO <FT_TAB>
"Here is the problem occurs, I want to grayed out the MATNR value based on some condition.
ENDLOOP.
I would like to set the 'MATNR' value to be grayed out by passing the CL_GUI_ALV_GRID-MC_STYLE_DISABLED.
and update into <FT_TAB>(       <FT_TAB> structure will have 2 structures)
Finally the fieldsymbol should have two structure ( <F_TAB> = DYNAMIC STRUCTURE + LVC_S_STYLE )
Display alv grid by passing <FT_TAB> to set_table_display method.
Thanks in advance,
Kumar.

Hi,
I am  not sure whether I really understand your request. Let me try to help.

Here <FT_TAB> must already be assigned to some internal table with a given (dynamic) structure. Did this happen before this piece of code?
What I would do is to create a dynamic table (see documentation to CREATE DATA) with MATNR and the STYLE field (LVC_T_STYL). See the documentation for CREATE DATA - creation of internal tables. When collection the field descriptions for that internal table I would also build the field catalogue for the ALV.
Then assign <FT_TAB> to that newly created internal table, <FS_TAB> to a newly created structure (same as a table line).
Move the MATNR to component 1 (or component 'MATNR') of the table and fill the style table according to your needs. Then insert the <FS_TAB> into <FT_TAB>.
Finally call the ALV SET_TABLE... method with your dynamic table and your field catalogue.
