Have you got the MIB definitions for the main table?
If you can let us have a copy of that, together with the structure of one of the
child tables,  we should be able to show you how to achieve this.

Thanks for your kindly offert to show me how to do the task.

Belowe I add the schema and the MIB descriptor of the what I want to build.
My problem is how to get a table crTablePanels and inside each of its row, named 
crEntryPanel I have to add and entry to crTableDevices, which is another table

In my previous version of this program I haven't the crTablePanels and the table crTableDevices where fitted just at top of schema ( cmv ).
At that time I have build the simple table using a pseudo-code like this 

    strcpy( table_name, "crTableDevices" );
    aesys_table_set_devices_devices = netsnmp_create_table_data_set( table_name );

    netsnmp_table_dataset_add_index(aesys_table_set_devices_devices, ASN_INTEGER );

    netsnmp_table_set_multi_add_default_row(aesys_table_set_devices_devices,
                                            COLUMN_INDEX,      ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_TYPE,       ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_STATUS,     ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_DESCR,      ASN_OCTET_STR, 0, NULL, 0,
                                            COLUMN_STATO_VIS,  ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_STATO_FLAG, ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_MSG_VIS,    ASN_OCTET_STR, 0, NULL, 0,
                                            COLUMN_REV_FW,     ASN_OCTET_STR, 0, NULL, 0,
                                            0);

    and for each row
    ==================
    netsnmp_register_table_data_set( reginfo, aesys_table_set_devices_devices, NULL);
    
    aesys_UpdateRowTableDevice( DEVICE_ALFA1,        0, CODICE_ALFA,  ilvl, stato_vis, stato_flag, msgvis, rev_fw, descr );
    aesys_UpdateRowTableDevice( DEVICE_PITTO1,       0, CODICE_PITTO, ilvl, stato_vis, stato_flag, msgvis, rev_fw, descr );
    ........
    netsnmp_table_dataset_add_row( aesys_table_set_devices_devices, rows[idx] );



    Now to add all this under inside crTablePanels I tough that should use somethink similar, 
    with a column type which refere to an instance to crTableDevices , but this is not supported

    strcpy( table_name, "crTablePanels" );
    aesys_table_set_devices_panels = netsnmp_create_table_data_set( table_name );

    netsnmp_table_dataset_add_index(aesys_table_set_devices_panels, ASN_INTEGER );

    netsnmp_table_set_multi_add_default_row(aesys_table_set_devices_devices,
                                            COLUMN_INDEXPANEL,    ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_TYPE,          ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_STATUS,        ASN_INTEGER,   0, NULL, 0,
                                            COLUMN_REF_TO_DEVICE, ASN_THIS_SHOULD_BE_A_REF_TO_TABLE, 0, NULL, 0,
                                            0);

    How can do to emulate it in someway ?


The code has comment in Italian language. 
I don't think this comment should be helpfull to understand the MIB schema, so I didn't translation for it, 
but if some translation is required let me known ans I will provide for that.
