gray out Budget Date , Accounting Date , Conversion Date and allow only defaults from our configurat

Summary:

Our current configuration - Invoice Date defaults to Budget Date, Accounting Date, Conversion Date
If Invoice date is closed period, Budget Date, Accounting Date, Conversion Date defaults to latest open period.

Example: Invoice Date May 10 2024 , June 2024 closed.
Then Budget Date , Accounting Date, Conversion Date defaults to July 01 2024.

above configuration works fine for us as longa s users do not override the defaults.

Let me know if any one come across with this requirement if we can gray out Budget Date , Accounting Date , Conversion Date and allow only defaults from our configuration.
