Every time DMM does an execution, it records an execution log for further reference. Also, the current progress is displayed on the reporting page during an execution.
Access "Reporting" on the top menu to view this feature.
Below the Running area, you'll find an overall status with the statistics of all data execution you've made with Infosistema DMM. Further down, there is the history of all executions you've made with Infosistema DMM.
For each line of the log table, you have the option to download the log file or to delete it.
Please note that if you need support from Infosistema regarding an error appearing in your system, this log file will be one of the first things support personnel will request from you.
