Explanation
The consultant should leverage the Open Date and Due Date fields to meet the requirement of making sure applications are unable to be edited after the submission deadline for the Admissions office that is using Admissions Connect to manage its student application review process. The Open Date and Due Date fields are fields on the Application object in Admissions Connect that allow users to specify when an application is open or closed for submission. The Open Date field indicates the date and time when an application can be submitted by an applicant. The Due Date field indicates the date and time when an application can no longer be submitted by an applicant. The consultant can leverage the Open Date and Due Date fields to meet the requirement of making sure applications are unable to be edited after the submission deadline for the Admissions office that is using Admissions Connect to manage its student application review process by configuring and customizing these fields to match their application deadlines and policies. Creating custom Open Date and Due Date fields, developing a custom trigger that checks the submission deadline against the current date, or activating the ApplicantCommunityHomePageController Apex class are not functionalities that the consultant should use to meet the requirement of making sure applications are unable to be edited after the submission deadline for the Admissions office that is using Admissions Connect to manage its student application review process.
