AX Session disconnected while item tracing

Hi All,

I am doing Item tracing in ax 2012 R3 from

Inventory management > Inquires > Tracing > Item tracing.

After completion of trace when I click to any button live customer, vendor or Production order for more detail on same form.Then its showing error message like "Your Microsoft Dynamics AX Session is no longer valid.
Log off your computer and log on again. If the problem persists
contact your Microsoft Dynamics AX administrator" and AX session get disconnected.

This error message is showing for some batch number only not for all batches

Please suggest any solution for this.

what about event viewer? any detail there?
