- SAP constantly tells customers to get rid o their custom code and to use SAP standard functionality. This old point has been brought up again with S/4HANA.
- How much of customers’ custom code is actually used by customers?
SAP proposes that very few custom coded objects for SAP systems are actually used. SAP has proposed that for companies that plan to implement S/4HANA, that the custom code is evaluated for removal. This has been a long-term strategy by SAP to get customers to use standard functionality, the problem being, SAP is always sold with the amount of functionality that will meet the customers being overstated, which we covered in the article How to Understand the Overamapping of ERP to Functionality.This leads to the question of how much custom code in SAP systems is relied upon by customers.
SAP Nation 2.0 on the Percentage
The book from SAP Nation 2.0 provides an explanation of how much custom code is used.
“According to Panaya, a tool vendor, “Our data shows approximately 50 percent of customers use 60 percent or less of their custom code. Being able to easily identify which parts of that code can be safety cleaned from the system can help reduce the future cost of such upgrades.“”
That is no the level of code used by customers communicated by SAP, which attempts to make the percentage utilized seem far less.
The fact is, that SAP customers do not think the latest versions of ECC are worth the time and expense to upgrade. Furthermore, many customers that do upgrade, would not have if they had fully accounted for the costs. One cannot listen to either SAP or to SAP consulting companies for objective advice as to whether to upgrade, as both entities make money from the upgrade process.
