Hi Prakhar, thank you so much for the links...they were VERY USEFUL!
I have completed all the steps in your links and have now setup ZSOLMANPRO Business Role. I have changed the logo text and can see this is now showing in CRM Web Client 
Only thing is, when I click on "Request Change Request" it doesn't give any transaction types (i.e. doesn't show SMCR or ZMCR).
If I switch back to SOLMANPRO, it shows both SMCR and ZMCR when I click on this link.
How do I assign transaction types to my custom Business Role???
Thanks
Shaun
