Bulk update allows you to update multiple cells in a column to a new value.
Unlike Smart Edit which updates the cell based on its current contents, Bulk Updates replaces the existing cell value with a new value that you specify.
You can do a bulk update on text, numeric and date columns. The input will change depending on the datatype of the column.
If the proposed Bulk Update breaks an validation rules then it will be prevented. (See Smart Edit for how this works).
