Thanks for the reply, Colin. I'm able to move CALs between documents no problem.
I currently have 8 CALs assigned to the second document. I'm running into a problem when I click Manage Users and attempt to add the first user. It appears to work and the Document CALs assigned to users goes to 1. Upon hitting apply the number then goes back to 0.
There are no free cals to allocate.
The issue is that the available server cals figure is zero - See the "Document Cals Not Allocated on this Server" value.
Reduce the 142 allocated on the other document first and click save. This will change the Available Server Cals from zero to a value. then your can add these unallocated cals to the second document.
I think you lost few cals.
Did you some how delete an application or rename something like this?
Not sure but check if this can help.
