That's a little too vague of a question, but yes, Postgres should be able to handle things just fine. The amount of SAP tools and SAP-supporting ETL tools that also support Postgres should be a strong encouragement. I'd recommend looking at the specific tools you would use and confirming they have Postgres support built in. Then try and find use cases / complaints for those specific items.
