Hi, @Sunil Jung — Clari inherits permissions from Salesforce, so this looks like something may have happened with your permissions to update this field in Salesforce. I would reach out to your Clari/Salesforce Admin to make sure you have permission to update this field.

Thanks for your comments

To change the date, I`d like you to check to Clari/Salesforce admin

Hi, @Sunil Jung — I need to defer to you or your team leader to touch base with your admin regarding your Salesforce permissions. Your Clari/Salesforce Admin is likely the Rev Ops or Sales Ops team that supports your sales org.
