Customer mentioned that his issue resides on having certain OUs that are not populating their AD structure reference under "Resource Manager>Summaries>Organization
AD Import is working just fine since the Inv_OU_Membership dataclass is populated with the proper references.
"Organizational Summary" is actually populated after a Delta Membership update and since he has it running every 2 hours, that is why he can't see rightaway those changes reflected after the AD Import.
There is not an issue here, just a misunderstanding on the process involved with the "Organizational Summary".
