Two weeks ago I wrote about how the world's largest exporter of dairy products uses SAP to support their huge delivery chain of dairy products. We recounted how Fonterra used an Application Performance Monitoring (APM) tool to discover that additional training for employees was necessary to speed up certain critical SAP transactions: some employees weren't optimizing attributes passed to the reports based on custom T-Codes. Unfortunately, additional SAP training cannot solve all the problems.

Performance problems with SAP delivery can quickly propagate to seriously affect business operations and lead to tedious war room scenarios. End-user complaints will usually point towards the SAP team, the SAP team will blame the network, and IT operations team will fight back.

The inability to quickly determine the root cause of the performance problem often leads to war room scenarios, especially when the mo... (more)
