defer panel updates for a subpanel VI being called by a parent

[id]

There is a good writeup on this topic

The ability to defer the panel from updating must be done in both the parent VI and subVI.  If the property node to defer the panel updates is embedded in the subVI due to specific code groups, does this mean that the parent VI Ref must be passed down into that code and deferred by its own defer panel updates property node in addition to the subVI's itself?

Anybody with experience on how to do this would be beneficial.

If you only want to defer the updates in the subpanel, then you do NOT need to defer the updates in the caller. The article you linked to talks about LV <8.2. I can say from experience that in later versions it works fine if you only defer the subVI.
