Has anyone used it? We are a Logistics company and wanted to use SAP for more than just the financial side of business.
The subject line for your message mentions All-in-One - I am assuming that you are inquiring about Business One.
SAP has four Products
SAP Business One
SAP Business By Design
SAP Business All-in-One
SAP Business Suite (MySAP/R3)
SAP Business One is for small to medium companies 1-200 million dollars in revenue is a very rough estimate for fit.
Business One and all of the SAP software offering are full ERP offerings and offer far more than just financials.
