The following record failed while converting PRI: 05.00.02.00:DATA:SO_InvoiceTierDistribution:000000:000 Error #88: Invalid/unknown property name. View the Activity Log to locate a specific conversion log."" Have I mentioned that the 2013 Sage Exchange conversion is the devil incarnate? This table has no credit card data in it but I still think it's related to Sage Exchange. Last time I saw this error message and said OK it was followed by a credit card error message. After that we deleted the credit card encryption key in company maintenance,which purged all CC history (also have used the utilities to do this as well), cleared out files in the destination location (Sy_CreditCardrestart), have rebuilt key and sort files twice for AR and SO, remigrated, converted, waited 4 hrs for this error to come up. Connecting back to server today at 2pm and looking for a miracle.
