Hi everyone, how can I edit the "Percent Complete" (percenttimecomplete) field of a project task manually or by user event script?, I understand that it is calculated automatically but for company reasons I must edit it

How is it calculated?

it makes (actual work / planned work) * 100 (native function)

Then you'll want to programmatically create more Actual Work and/or reduce Planned Work, presumably via Time Entry records.
