Microsoft Project

Hi Mark

Thank you for your question and welcome to the Forum.

By default MS Project has a setting switched on that tries to auto link inserted tasks. Generally this is not very helpful as the links created are not based on the task logic but always default to Finish to Start. The setting can be turned off by going to Tools > Options > Schedule and removing the tick from Auto link inserted or moved tasks.

Generally it's more reliable to manually link inserted tasks to make sure they follow the logic you require rather than a default Finish to Start.

I hope this helps - do let us know if you have any further questions.

Kind regards,
Andrew
