How to Process Weekly Time Entries with SuiteScript afterSubmit

When a weekly time tracking form is saved, NetSuite automatically converts the aggregated weekly entries into individual daily time entries, processing them column by column and row by row. For solutions involving custom fields where values need to be managed or updated post-submission, an afterSubmit user event script can be utilized. It is crucial to note that within the afterSubmit context, the newRecord object is read-only. To perform additional updates to the newly created record, the script must explicitly load the record, apply the necessary modifications, and then submit it. To prevent the script from executing redundantly or causing infinite loops, a condition should be implemented, often based on a custom field. This custom field's value will differ when set on a weekly time entry form (column-level) versus a daily time entry form (header-level), allowing the script to differentiate the context of execution.
