Hi All,
Below I have briefly explained problem and its solution so that it might help someone out there. Please do update your comments/feedback, if someone find it helpful.
Problem:
We faced an un-desired behavior in AX 2012, it started throwing "Cannot create a record in Inventory transactions (InventTrans). The record already exists." with every transaction that was being created in InventTrans from any Dynamics AX module.
Solution:
We did following steps that resolved the issue:
1. Open AX client and
2. Switch to development workspace (Ctrl+D)
3. Cleared all cache/garbage object shown in screenshot below
4. Restart AOS service
5. Start the AX client again, create & verify InventTrans transaction
Regards,
Irum
