Just a FWIW. While inspecting a client's IM_PeriodPostingHistory file for a blank warehouse code issue, I noticed the Data Conversion from 4.3 to 4.4 had created an empty beginning balance record in fiscal period 01 for every fiscal year up to 2094 for every item in all warehouses including the blank one. GL and IM setup seem clean and I have no idea why it decided to stop at 2094.
