I am integrating the datamart in mr for sl 2018 but I waited more than 6 hours and it never finished, then I canceled and tried it again and I realized that the database was bigger. Do you know how I can solve it or what is the problem?

Any luck with the initial integration? Are there entries in either the MR integration log (check from the configuration console) or the local server's Windows application event log?
