The loadrunner scenario is the combination of all of the running scripts, not the individual business processes. If you have 100 different business processes present then I would submit to you that you are commingling functional and performance testing, because even the most complex mutli module installation of SAP is unlikely to have 100 business process under load. Yes, there may be 1000's of actual business functions, but only a small minority are responsible for the majority of the load. Do not take my word for it, look at your HTTP access logs and search for frequency of unique page names blocked by hour. It will become apparent. The other possibility is that you simply do not know how to parameterize script effectively. We saw this with Healthcare,.gov where hundreds/thousands of scripts were being produced with single sets of data because the end users of LoadRunner were untrained in the tool. You can parameterize a business process script for hotel name and use the same script for 20 different hotels assuming a commonality of business process.
