Hello,
We are experiencing an issue related to PSO manual changes (drag & drop rescheduling in the PSO gantt).
We are on 6.14.0.27 as of Saturday Feb 01 2025.
What we are seeing is as follows:
- A user will drag the activity to a new location (either same resource, different time or a different resource & different time)
- Then when the activity is “dropped” (manual change initiated), the manual changes side bar / pop out box will be opened
- However, the “Validate and Apply Changes” & “Apply Changes” & “Validate” buttons will be greyed out., The option is Cancel
- This is the case with Preview Changes applied or not applied
- The target (updated) date & time field will be reflected in the manual changes box, but PSO is not detecting that changes have been made
- If the user then makes a subsequent change to any field in any of the fields in the manual changes side bar / pop out window or drags the activity icon a second time, only then are the change buttons available to select.

Could the issue be related to any of the following updates in the release notes?
- CS0328702 - Fixed issue with resource selection not being populated correctly for manual changes of activities that are fixed to a resource.
- CS0313356 - Fix activity labels not displayed in gantt issue
