"Well-integrated system that functions well with our current infrastructure and processes"

4/5

What do you like best about OneStream - Unified EPM?

It is an integrated system that works well with our current infrastructure and processes, including SAP, and the retrieve function for review and analysis is very useful. I use this system on a weekly basis for various reviews and analyses, quarterly for forecasts, and annually for budgets. Review collected by and hosted on G2.com.

What do you dislike about OneStream - Unified EPM?

The budget and forecast process could be further improved by allowing the same GL setup in SAP to be brought into OneStream. This way, we will be able to analyze using the existing breakouts (UD2/UD4) and also via specific GLs for easier comparison of actual vs forecast. Review collected by and hosted on G2.com.
