The ability for planning users to add commentary is crucial, particularly when that commentary is stored in the database alongside the plan data – not just on the surface level of the planning system. Commentary adds verbose context to plan data and can be used for budget justification, the explanation or description of individual costs. For example, if your budget for in-person training is lower this year because many of the courses can be attended online, that information is considered commentary and should be entered into the planning system.
