Hi,
I created a custom entity to display under Settings tab by selecting Settings checkbox under "Areas that display this entity" on form information. I added only this custom entity on a solution on Dev environment. It appears under Settings tab in Dev environment. I exported the same solution and imported to other QA environment and published. But it is not appeared under Settings tab in QA. I open the entity on QA and verified Settings checkbox. It is not checked (ticked). It is strange. Am I missing something or CRM 2011 import solution won't consider "Areas that display this entity".
