We are facing issue wherein users of certain region are facing problem using the SAP system. For example when trying to load certain cProjects on the system it takes lot of time to display the output. Its a ERM system basically SAP ECC6.0, please suggest how should I find out the RCA as I have already tried and check the following which are in good status.
1. Data buffer quality
2. CPU and Swap Utilisation
3. No jobs in Waiting status
4. Maximum Dialog wp are in waiting status
5. No Sap and DB lock found
6. No Update request hanging
Note:- Only one WP is in Waiting status but in Error 01 I dont think so it should affect the whole system performance. This happened on 23rd Oct can we check some data from SAP for this date which lead the system performance to degrade on this day?
