Just did a 4.3 to 4.4 upgrade (client has a rental vertical) and the purchase order folder on the launcher menu was blank. We have seen this before, copied the text for the PO module from the 4.4 install on my laptop to the MNUMOD.TXT file and that took care of it. Then I added crystal reports back to the custom reports folder in payroll, work order and time card (all legacy modules that were getting the ""Requested Program not Installed"" message and had the old file names prw100.rpt) and when the menu recompiled it blew the purchase order text away again. I went back, added it and now the custom reports folder for the Inventory module is empty. When I run the SY_MENU_UI utility the inventory folder is empty (as it is on the launcher), the custom reports I added back to the legacy modules are unchecked yet they show in the launcher (have tried checking them, accepting, resetting...).
Needless to say this is driving me nuts. The knowledgebase suggests going to a backup - but there never was a ""good"" file in 4.4 because of the upgrade process. Any suggestions besides drinking heavily?
