Normally when monitoring process chains I used to execute the transaction code RSPCM. The overview which this t-code generates does not always show the most accurate information regarding the state of the process chains.
Many organisations have therefore implemented the program /SSA/BWT. Sometimes this program is assigned transaction code ZMONITOR. This program, which can also be executed via SE38, has various options available.
The first option, process chain analysis, lets you analyse all the scheduled and nonscheduled process chains in BW. In order to do this, execute the program in SE38, fill in the variables (if applicable) and hit F8. You also have the possibility to filter out certain statuses immediately. Once executed it will display an overview as shown below.
One of the great features of using this program, is the ability to compare the runtimes . This can be done easily by requesting a larger timeframe for a given process chain and sorting the result based on the columns CHAIN, Day Date and Time.
