Hi,
Actually there is no table which shows process chain start and end times at once.
above table will shows process time which take to to finish one step(info pack load or DTP or etc) only.
While seeing data you need to see for which step(process type) your checking.
Assuming this is your chain design.
Start variant-->info pack-->dtp to DSO-->dso data activation--->delete index--->dtp to cube--->create index--->rollup.
If you want see how much time taken by your chain then do like this.
Go to your chaiin at RSPCM or RSPC
Click on your chain, select start variant--> display ,message--> see here start time.
later go to same chain, last step, example as roll up --> rigth click-->display message, see the end time.
Thanks
