Runtime Error with common_ds.executeQuery()

I have an Axapta Crash while i’m doing some salescopying from salestable. The message is : " SmartHeap Library , Runtime Error, Abnormal Program Termination". I succeed to find the line that is running bad, it’s in the method refreshCaller of the form SalesCopying, at the line 15: common_ds.executeQuery() Plus, the TTS level is at 5. Does anybody know why the ExecuteQuery cannot run ? It’s very important because this is a standard process of Axapta 3.0 SP2. Thanks, Bertrand Caillet, DEROCHE S.A.
