How to restrict 'Next Activity' selection to only the next in sequence and 'None Ordered'?

Summary:

Need to update the ‘Next Activity’ selection logic to restrict options to the next assigned activity and any ‘None Ordered’ activities only.

We need to refine the behaviour of the ‘Next Activity’ pop-up that appears upon completing an activity. The updated logic will need to limit the selectable options to:

• The next assigned job activity (based on current activity order).
• Any activities marked as ‘None Ordered’.

This change we hope will ensure a streamlined workflow by guiding users toward the most relevant next step while still allowing flexibility for un-sequenced tasks. No other activities will be displayed in the selection list to avoid confusion or deviation from the intended process flow.
