Unexpected tempdb growth

Hi Friends,

We have installed SAP IDM on MSSQL Server 2012 and for the last few days, we noticed that the TEMPDB data growth has gone high to around 30 GB whereas the IDM DB size is of just 5GB .

Surprisingly, the IDM DB log has also grown to 13GB.

Can someone explain to me the reason why the DB log and tempdb data file size is increasing rapidly?

Thanks and Regards,
