General Troubleshooting Tips

Record Locked by Another User

If you have ended Microsoft Dynamics NAV in busy mode, and then restarted Microsoft Dynamics NAV, you may experience the following error message: “Record locked by another user”. This is caused by a lock on data in a job that is still running on the server.

To release this lock, you must either shut down the SQL server manually, or restart the Microsoft Dynamics NAV Server session using the Microsoft Dynamics NAV Server Administration tool.

Sorting Actions in System Groups

In the Microsoft Dynamics NAV Windows client, you cannot order actions in system groups in the Home tab.

Remove all actions from the group, apply changes, and then add the actions again. This will ensure that metadata is created for all actions and that they can be sorted as you want.

Removing Promoted Actions in Home Tab

In Microsoft Dynamics NAV removing a promoted action in the Home tab, and then re-adding it in the same session will cause duplication of the action.

Remove the action, apply changes, add the action again, and then apply changes. Or, remove the action, add it again in same session, and then apply changes. Remove duplicate instances and apply changes.

Compression Option in IIS

Users may experience slow mobile client responses especially noticeable when they are running with a slow network connection. The reason for the mobile client running slowly can be that the dynamic compression is not enabled on the IIS server.

Configure HTTP compression of dynamic content to use bandwidth more efficiently. Enabling dynamic compression always gives you more efficient use of bandwidth, but if your server's processor utilization is already very high, the CPU load imposed by dynamic compression might make your site perform more slowly.

You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.

1. 
   

   Open IIS Manager and navigate to the level you want to manage.

   
   


2. 
   

   In Features View, double-click Compression.

   
   


3. 
   

   On the Compression page, select the box next to Enable dynamic content compression.

   
   


4. 
   

   Click Apply in the Actions

   
   

The File that You Are Trying to Use Is Too Large

If you are trying to upload a large image file that is larger than 4 MB in size, such as a high-resolution photo, Microsoft Dynamics NAV will give you an error message saying that the file you are trying to upload is too large. This behavior can be changed by modifying the IIS configuration to support large file uploads.

The IIS administrator should make the following changes in the Internet Information Services (IIS) Manager.

1. Launch the IIS Manager.


2. In the left pane of the IIS Manager, select the Microsoft Dynamics NAV web site, and choose Request Filtering.


3. In the Actions pane of the Request Filtering window, choose Edit Feature Settings.


4. Set the field Maximum allowed content length (Bytes) to an appropriate value, such as 100000000 and choose the OK button.


5. In the left pane of the IIS Manager, select the Microsoft Dynamics NAV web site, and choose Configuration Editor.


6. In the Configuration Editor, make sure that the From field is set to Microsoft Dynamics NAV 2013 R2 Web Client Web.config


7. Set the Section field to system.web/httpRuntime and now a number of properties will appear.


8. Set maxRequestLength to an appropriate value, such as 100000 (kilobytes) and choose the Apply action on the right.


9. Close the IIS Manager.

The new settings should take effect immediately without refreshing the IIS or the site.
