Issue with editing the ETC from the Assignments module, no matter if its zero or greater. It’s possible entering in each task assignments, but you cannot edit it in the Assignment flyout. Are there options to be able to edit ETC in the Assignment module?
Expected result: ETC field is editable
Actual result: ETC field is not editable and you have to edit it in the assignments of task instead of the assignments module
Not being able to edit the ETC on the Assignment Module flyout is by design. However, there are available options to edit ETCs in the Assignment module.
There are a couple of options to edit ETCs on the Assignment module. This can be done by adding the ETC Totals field to the column list or the ETC for Per Period Metrics.
As long as Totals columns in View Options is set to Sum of Periods (not Grand Totals), the ETC Totals field is editable.
Below a screen shot from the column list that shows which ETC column is editable (the one under Totals)
Additionally, if you have ETC added in Per-Period Metrics (available in View Options), you can edit ETC directly in specific periods as well (this can be done whether using Sum of Periods or Grand Totals).
