During each MRP refresh two Output log files are created.
The Log File includes full details of the demands and replenishments that were included, and the calculations which lead to each recommendation.
The Errors file lists any errors that were encountered during the refresh, with details of the causes.
The output log is useful for explaining why a recommendation was made and for its quantity, date, etc.
Output logs are created for each MRP refresh; they can be accessed from the MRP List View at any time.
