Todd,
Thanks for the reply. I don't know what was happening with my cost updating, but it seems to be workign properly now.
Cost Update Method = Weighted Average. Always has. This is true for all four stores.
I can show Item Movement Report and PO History examples of items where the cost did not update correctly. More than one or two examples. This has happened at multiple stores. Transfer orders always seemed to work as expected.
Recent (this week) test POs updated costs as expected.
Most of the problems I noticed were with serialized inventory.
At present, the problem seems to have resolved itself. I did get the hotfix to update my 1.3.1004 to 1.3.1011, but the issue mysteriously went away before I applied the hotfix. I may simply wait for 2.0.0002 (or ...3) and move to v2.0 at that time.
Again, thanks for the reply.
Tom
