In attempting to SetValue the StandardUnitCost in CI_ItemCode_Bus, I get a return code 1 on the SetValue and subsequent Write; however, the StandardUnitCost is not changed. After the retVal = 1, the LastErrorMsg is set to ""Module W/O is not on file"" WTF? This is the ABC company. Not sure the message is related to the StandardUnitCost not being changed. Does anyone know how to work around this peculiarity?
