These columns cannot be updated manually or through scripts, including via GlideRecord operations such as update(), or updateMultiple(). Steps to Reproduce: 1. Create a table that contains a column with a calculated value.Example: A column named "status" on a custom table like "u_custom_table". 2.Insert some records into the table for test puropses. 3.Run the following script in the Background Scripts module: var gr = new GlideRecord('u_custom_table'); gr.query(); gr.setValue('status', 'new'); gr.updateMultiple(); 4.Observe the result that all records appear unchanged. 5.No error can be found in the system logs. Root Cause: A column with a calculated value is defined in the system dictionary with the following configuration:- The Calculated property is set to true.- A Calculated Value script determines how the column value is generated.- The value is not stored directly in the database, but dynamically computed at runtime. Therefore, any attempt to change the value using GlideRecord or manual UI updates will be overridden by the logic in the Calculated Value script. Workaround: - Disable the Calculated property if business logic permits.- Or create a separate, non-calculated column to store editable values.
