Not sure why anyone would compare inoERP with SAP. SAP is big.100 times bigger than inoERP. Used by many large MNCs. On the other hand, inoERP is a small open source application used by mostly small startups.
It's not that inoERP is bad, but it should not be compared to SAP.
The only thing in inoERP that is better than SAP is the accounting processes. Accounting in SAP is a complete Joke. And, as inoERP is more like Oracle, the accounting process is way better, robust, and flexible compared to SAP. Everywhere else, SAP is 100 or even 1000 times better.
