I need to create a Service Request process which will automatically update given CI in a certain circumstances. Tb be more precise; SR for a software which will require a license. Now in CMDB there will be "license CI" which will feature a number of available licenses for this software. Upon acceptance of such SR, license will be granted, and automatically number of such licenses in the CI should decrease by 1 (or more).
Any suggestions how should I go about it?
