Update query

Hi All,

When i write update query for system table for UDO table i get mesage as

"Another user modified the table" when i ciick on update button.

Update is not recommended for system and UDO table when i went through the SDK coding standards.

Is there any another option other than wrting the Update query to update the system and UDO table.

Like we have for insert through DI API .

Plz suggets
