From time to time it may become necessary to rebuild your data file. Doing so can allow your computer to take advantage of new features that OnTime will implement from time to time and sometimes help resolve synchronization issues.

Before getting started, here are a few things to keep in mind:

• NOTE: If you have added, modified, or removed any information from OnTime since the last time OnTime was synchronized with the OnTime service, be sure to perform a synchronization. If a synchronization is not preformed, those changes may be lost since a rebuild of your data file discards the existing OnTime data on your computer and downloads a fresh copy from the server. You can always check for pending changes by following these steps:

  If the computer shows zero as the number of pending items, then you are ready to rebuild you data file.
   
• NOTE: If you have both OnTime Management Suite AND OnTime Dispatch installed on the same computer, you do not need to rebuild the data file in both programs. Since both programs share the same data file, you only need to rebuild from one of the programs. It doesn’t matter which one.
   
• NOTE: Before performing the steps below, please close ALL OnTime applications running on the computer and then reopen only one OnTime program to perform the rebuild. Open OnTime programs can cause the data file to be locked and prevent the rebuild from succeeding.

How to rebuild your data file in OnTime Management Suite:

1. From the File menu, choose Data File Management.
2. Click the link labeled Rebuild Data File…
   
   
    
3. Once started, the process can take several minutes to complete. During that time, you should avoid using OnTime. You will know when the rebuild is complete by watching the progress displayed in the lower right corner of the OnTime application window.

How to rebuild your data file in OnTime Dispatch:

1. Ensure that you have no open order entry forms in the shipments view.
