Kevin,
Only enable_table value change is sufficient. yes you have to restart the Agentry app after changing in configpanel.
in this case Agentry client will call complex table class but as the enable table value is 0 so the return value from Java will be 0.
if you remove all the complex table from agentry editor, no doubt the complex table download request will not go to server. but the problem is in future, if you need these complex tables you have to rewrite in Agentry editor or you can restore it from Trash(if you haven't cleared your trash). which is risky sometimes. so its recommended to change the Enable_table value in SAP configpanel.
Hope this makes you clear
Thanks
Ajitesh
