I was asked a question this morning that I don't think I have discussed in a previous blog article.

A partner was concerned whether web services interactions could cause a potential conflict with other users accessing Sage CRM through the main interface.

Basically, does a web service request consume a concurrent license?  The answer is no.  The SOAP Web Service logon is an additional login.

See below.   You can see that I have opened several connections to Sage CRM and I am looking at the screen created by looking at the information screen

http://localhost/crm/eware.dll/sysadmin

My system allows for 3 concurrent users.  In the fourth tab from the left, I had tried to log in as 'Matthew Ebden' but received the classic message 'Maximum number of users already logged on. Please contact your System Administrator'  but you can see that I have been subsequently able to log in using my Web Services test app.
