upgrade from 4.3 to 2014, with DSD APMU multi-company. When we try to go into invoice data entry just for one company, the rest work, we get: ""The file AP ExpenseDistTableHeader is being used by another task and cannot be opened."" Full error message attached. ExpDist tables has not been turned on for this company, rebooted server, made sure DSD conversion has taken place, when I go into AP options and try to enable exp dist tables it tells me I need to: Enable wire transfers, The Next Vendor Remittance Advice Number is required (what???) and The Print Aged Invoice Report for Multiple companies is required. Also reinitialized ap invoice entry files. My next step will be to copy the 4.3 data back in and reconvert unless anyone has any suggestions.
