I did configuration to activate 'End-to-End' Monitoring in RWB. After 'Save Configuration' and troubleshoot thru tcode SPIP (As said in SAP Note 885405) , the following error comes.
07.02.2008 21:26:25,341000: Transport of local PMI data to PMI system
Preparing destination: PMIPID00120080207
RFC error: Password logon no longer possible - too many fail
PMI data from destination PMIPID00120080207 not available
One point I found that is If we press 'Save Configuration' button in RWB, the user 'PIRWBUSER' is automitically locked.
So, How to solve this issue ?
