If/where does Dynamics FS store the exact timestamp of Booking Status changes (offline scenario)?

(0) ShareShare

Hi all,

We are working on an integration between Dynamics 365 Field Service and a third-party scheduling tool.

 

When technicians update the Booking Status on the Bookable Resource Booking (BRB) via the Field Service Mobile App, the record in Dynamics only shows the modifiedon timestamp — i.e., the time when the change is processed in Dataverse.

Our concern is the offline scenario:


  • If the technician is offline and changes the status (e.g., “Traveling”), the record syncs later.

  • In that case, is there anywhere in Dynamics where the actual action timestamp (the moment when the user pressed the status change while being offline) is stored?

  • Or is the only available value the Dataverse processing time (modifiedon)?


  •  

We’ve checked the BRB entity itself and can't see such a field. Does this information exist somewhere (audit logs, related entities, mobile metadata), or would this require a customization on the mobile client to push the action timestamp into a custom field?

 

Any guidance from the community would be much appreciated!

    Can anyone confirm if this is correct?
     
    Apparently: 
    • If the technician uses the official Field Service Mobile app, Dynamics will capture the real offline action time in Booking Timestamps entity.
    • If a custom or third-party app is used, it will capture the real action time only if the app is specifically designed to create Booking Timestamp records. Otherwise, only the Dataverse processing time will be available.

    No, Dynamics 365 does not natively store the “actual offline action timestamp.”
    You will need a customization on the mobile client to capture and persist that value.
    If your integration with the third-party scheduling tool relies on the real action time (e.g., travel start, work start, completion), then you’ll need to:
    • Create a custom field (e.g., ActionTimestamp).
    • Configure the mobile app so that when a technician changes the Booking Status, the client sets this field to the device’s local timestamp.
    • Use that field in your downstream integration logic instead of relying on modifiedon.
