I checked the RH 2015 online Help but didn't see the confirmation that I was looking for about User Defined Variables (UDV).
What I wanted to confirm is that the SystemName_Cardiac_Monitoring_System UDV and its value displaying in bold below means that it is a different value than in the default UDVS. I think that's what it means because I created a second User Defined Variable set and set the UDV named "SystemName_Cardiac_Monitoring_System" to "Xcelera" in the "Demo" UDVS (User Defined Variable Set) whereas the value in the "default" UDVS is "Phillips." Can anyone confirm that's why the value is bold?
Indeed, that's my own understanding of it. And you are right, I don't believe that specific behavior is mentioned anywhere.
Something else I just noticed that might be helpful when working with UDVs is that if you want to change the Description field, it can only be done when you are working with the Default Variable Set value selected in the Variable Set drop-down. I created a variable set called "Demo" and that field is disabled when I have the Demo value selected in the Variable Set drop-down. I think the programming logic under this is that it's treating the Variable Name and Description as "key" fields in the database.
I'm not saying anyone would want to change the Description value - it is just something I noticed.
