The deploy and export history is logged. Over time, the number of logged records grows. To limit the number of logged records in the database, you can refresh the history. If you refresh the history, the retention settings of these Data modeling studio parameters are applied:

• Log record retention (days): On refresh, only the log records are kept that are within the number of defined retention days.
• Processing record retention (days): On refresh, only the processing records are kept that are within the number of defined retention days.

Example: Number of retention days is 7. Today you Refresh. As a result, all logged records are deleted that are older than a week.

Standard procedure

1.	Go to Data modeling studio > Data modeling studio > Data exchange monitoring.
2.	Click Refresh.
