The Model Data Reuse (MDR) command generates a log file for each MDR operation. This log file contains information about each design object that was part of the operation. For the objects that were successfully copied, the original object ID (OID) and the copy OID are shown in the log. For the objects that failed to copy, only the original OID displays.
Use Windows Explorer or another browser to locate the MDR log file, which is stored at %temp%. The name of the log file is MDR[file_number].log where file_number is replaced by a number to make it unique. The text file appears similarly to the one shown in the following illustration.
