Computing Center Managing System (CCMS) T-Codes and descriptions

Spread the love

CCMS (Computing center Management System) is a systematic monitoring and alerting system in an SAP system. An online business application software needs continuous monitoring to fix the bugs. You have to periodically perform different health checks in an sap system to make it work ever without breakdown. I am listing some of the T-codes for your reference, which are most important to do performance tuning of an SAP system. I have also provided descriptions of all the transaction codes in the following list. Please go through the list and try to execute in your SAP Netweaver or ECC system once to gain instant knowledge on each and every t-code.
