Aras losing data

Question

Hi Team, 
 I am experiencing a serious problem with my one Aras instance. We are losing data in the system, it is just disappearing without a trace. The user would add data, and then checking the next day, it is gone, without a trace, not even in the history file. 
 My gut feeling is that transactions in SQL was being rolled back, without being committed. I pulled a report from SQL and there seems to be rollbacks aligned with the data loss. 
 As part of this Aras instance I am creating a CAD interface in C# .NET. I am exclusively using applyAML() to talk to Aras, I am not using applySQL. Could I be doing something wrong in .NET? 
 
 Kind Regards 
 Riaan

Hi Team, 
 
 I have finally discovered the reason for the data loss of one of users of my CAD integration tool. 
 For future reference, here is the scenario, that led to it: 
 1) A part exists in Aras without CAD. 
 2) The user opens the Part in Aras, sees that there is no CAD attached. 
 3) He opens the CAD integration tool, which is a C# application. 
 4) Loads the file from CAD to Aras, also adding some extra fields, like design notes. 
 5) Closes the integration tool. 
 6) Goes back to Aras and adds some more stuff to the Part, for example linking a document. 
 7) Tomorrow morning opens the Part, and the CAD is missing! 
 ...........The issue came that in Step6, he did not refresh the Part in the browser and edited the previous generation of the part, the one before the CAD was added. Aras did not commit the CAD work and he was left with only the Step6 generation of the Part. 
 The only solution which I can think of at the moment is user training. 
 
 Such a simple issue that led to a lot of sleepless nights!

Many thanks for sharing your insights! That&acute;s a very interesting scenario that can happen to all of us! 
 Out of interest &ndash; which Innovator version do you use? Based on the mentioned Method, you seem to use Innovator 14+ , but is it higher or lower than Innovator 23? 
 If you are below I23, your described behavior somehow fits to this issue: www.aras.com/.../warning-versioning-and-tab-pane-very-buggy-in-new-innovator-versions-are-you-affected&#160; 
 You don&acute;t have to read the full thread. But the main issue I tried to point out was, that old revisions of an item can overwrite the latest one without the user&acute;s knowledge. This behavior in worst case could lead to severe data loss. 
 The issue was caused by a corrupted lock behavior and repaired in I23. In your context it sounds somewhat familiar, so I wonder if these two are connected?
