Read-only Fields: Business Rule and Imports

Posted on by Alan Roberts

I have a business rule, set with entity level scope, that states that field X is locked once it contains data. I have noticed that during a data import (using "import from Excel" I can still modify this field. Is this the expected behaviour? If so, what are my options for making fields effectivelly write-once? Do I need to use Field Level Security and/or JavaScript?

Thanks

Alan

Hi,

You should write plugin on Update message and throw an error when field X contains data if you don't want to write data if it's already contains data.

You should register pre image to check if OLD value of field X is not null.
