Create a custom formula column in Prod. Codes that shows the change in the final forecast, with the period "day". Then you can see right away where changes have happened today.
How to do it
Go to Prod. Codes.
Click Columns at the top right, select Custom columns and click + Add. Set Type to Formula.
Select the variable for final forecast (expected final cost) in the Formula field. Click Period, select Day and click Confirm, so that the column shows the change today.
Give the column a name you recognize, for example "Change in final forecast today", and click Save.
Sort on the column to get the production codes with changes at the top.
Good to know
The column is especially useful when many users work in the same project and the project manager wants to see what has changed.
You can use the same formula with a different period, for example week or month, if you want to see changes over a longer time.
Save the column in a shared table profile if several people are going to use it.
