Find a transaction by transaction parameter (TSTCP)

Would you like to find a transaction which has some specific parameters defined?
Let’s assume you know standard SAP RW report code (e.g. 9SIP-00, see trnx GRR3 for displaying th report), thus know report group it belongs to (9SIP). Now you might want to find S_ALR_* transaction which starts this report.
In this situation we know that such s_alr_* transaction must have RW group name in parameter D_SREPOVARI-REPORT and has to use START_REPORT transaction to start the report.
Good news! You could use table TSTCP table with search criteria for PARAM field like: *start_report*9SIP*.
