(Most of ERP is OLTP, i.e. most key performance indicator on write instead of read like BW and Scale-out support well on statement-routing, client distribution to balance workload on read dynamically while write may get impact or give big overhead if table write happened across all node, since one node write failed, it need to roll back the whole transaction across all node.
ERP is OLTP type, so a lot write happened at the same time, and transaction manager may control easily if it is not scale out.)
Hope this could help you in the future.
