In SOAMANAGER one can see the logs\traces of any WS call that was made to the ABAP system.
The Logs and Traces tab is very user friendly and useful if someone wants to see the payload trace (the XML) of every call.
However - there is no option of configuring for how long the data is maintained in the system.
I've looked all over help.sap.com and found lots of information regarding how to use the Logs and Traces options - but there was no information whatsoever regarding logs retention period.
There are plenty of reasons to care about the retention period - from just looking up old logs for analysis to maintain table spaces.
After some more digging i came across the following note:
https://service.sap.com/sap/support/notes/1311277
This note is very useful and gives a good insight on the logs retention mechanism,
To make a long story short - the default retention period is 72 hours, and it is maintained in a table called SRT_MONILOG_CUST
It affects the following tables (data growth wise):
SRT_MONI_PAYLTRC
SRT_MONILOG_DATA
SRT_MONILOG_DATA2
